Method Detail

setName

public void setName(String name)

getName

public String getName()

Description copied from interface: GigaSpace

Returns the name of the giga space. If it is configured with Spring for example, will return the bean name, if not, will default to the space name.

Specified by:

getName in interface GigaSpace

setDefaultReadTimeout

public void setDefaultReadTimeout(long defaultReadTimeout)

Sets the default read timeout when executing read(Object) or readIfExists(Object) operations.

setDefaultTakeTimeout

public void setDefaultTakeTimeout(long defaultTakeTimeout)

Sets the default take timeout when executing take(Object) or takeIfExists(Object) operations.

setDefaultWriteLease

public void setDefaultWriteLease(long defaultWriteLease)

Sets the default write lease when executing write(Object).

getSpace

public IJSpace getSpace()

Description copied from interface: GigaSpace

Returns the IJSpace used by this GigaSpace implementation to delegate different space operations.

Allows to execute space operations that are not exposed by this interface, as well as using it as a parameter to other low level GigaSpace components.

If a transaction object is required for low level operations (as low level operations do not have declarative transaction ex) the GigaSpace.getTxProvider() should be used to acquire the current running transaction.

Specified by:

getSpace in interface GigaSpace

getClustered

public GigaSpace getClustered()

Description copied from interface: GigaSpace

Returns a clustered view of the GigaSpace is this is a GigaSpace that worked directly against a cluster member. If this is an already clustered view, will return the same instance.

Specified by:

getClustered in interface GigaSpace

getTxProvider

public TransactionProvider getTxProvider()

Description copied from interface: GigaSpace

Returns the transaction provider allowing to access the current running transaction. Allows to execute low level IJSpace operations that requires explicit transaction object.

Specified by:

getTxProvider in interface GigaSpace

getExceptionTranslator

public ExceptionTranslator getExceptionTranslator()

Description copied from interface: GigaSpace

Returns the exception translator associated with this GigaSpace instance.

Specified by:

getExceptionTranslator in interface GigaSpace

clean

public void clean()
           throws DataAccessException

Description copied from interface: GigaSpace

Cleans this space. The side-effects of cleaning the space are:

• all entries and templates are deleted.
• all storage adapter contexts are closed.
• all engine threads are terminated.
• the engine re-initializes itself.

Specified by:

clean in interface GigaSpace

Throws:

DataAccessException

See Also:

IServerAdmin.clean()

clear

public void clear(Object template)
           throws DataAccessException

Description copied from interface: GigaSpace

Removes the entries that match the specified template and the specified transaction from this space.

If the clear operation conducted without transaction (null as value) it will clear all entries that are not under transaction. Therefore entries under transaction would not be removed from the space.

The clear operation supports inheritance, therefore template class matching objects and its sub classes matching objects are part of the candidates population to be removed from the space. You can in fact clean all space objects (that are not under transaction) by calling: gigaSpace.clear(null).

Notice: The clear operation does not remove notify templates i.e. registration for notifications.

Specified by:

clear in interface GigaSpace

Parameters:

template - the template to use for matching

Throws:

DataAccessException

See Also:

IPojoSpace.clear(Object,net.jini.core.transaction.Transaction)

count

public int count(Object template)
          throws DataAccessException

Description copied from interface: GigaSpace

Count any matching entry from the space. If a running within a transaction will count all the entries visible under the transaction.

Specified by:

count in interface GigaSpace

Parameters:

template - The template used for matching. Matching is done against the template with null fields being wildcards ("match anything") other fields being values ("match exactly on the serialized form").

Returns:

The number of matching entries

Throws:

DataAccessException

See Also:

IPojoSpace.count(Object,net.jini.core.transaction.Transaction)

count

public int count(Object template,
                 int modifiers)
          throws DataAccessException

Description copied from interface: GigaSpace

Count any matching entry from the space. If a running within a transaction will count all the entries visible under the transaction.

Allows to specify modifiers using ReadModifiers which allows to programmatically control the isolation level this count operation will be performed under.

Specified by:

count in interface GigaSpace

Parameters:

template - The template used for matching. Matching is done against the template with null fields being wildcards ("match anything") other fields being values ("match exactly on the serialized form").

modifiers - one or a union of ReadModifiers.

Returns:

The number of matching entries

Throws:

DataAccessException

snapshot

public Object snapshot(Object entry)
                throws DataAccessException

Description copied from interface: GigaSpace

The process of serializing an entry for transmission to a JavaSpaces service will be identical if the same entry is used twice. This is most likely to be an issue with templates that are used repeatedly to search for entries with read or take. The client-side implementations of read and take cannot reasonably avoid this duplicated effort, since they have no efficient way of checking whether the same template is being used without intervening modification. The snapshot method gives the JavaSpaces service implementor a way to reduce the impact of repeated use of the same entry. Invoking snapshot with an Entry will return another Entry object that contains a snapshot of the original entry. Using the returned snapshot entry is equivalent to using the unmodified original entry in all operations on the same JavaSpaces service. Modifications to the original entry will not affect the snapshot. You can snapshot a null template; snapshot may or may not return null given a null template. The entry returned from snapshot will be guaranteed equivalent to the original unmodified object only when used with the space. Using the snapshot with any other JavaSpaces service will generate an IllegalArgumentException unless the other space can use it because of knowledge about the JavaSpaces service that generated the snapshot. The snapshot will be a different object from the original, may or may not have the same hash code, and equals may or may not return true when invoked with the original object, even if the original object is unmodified. A snapshot is guaranteed to work only within the virtual machine in which it was generated. If a snapshot is passed to another virtual machine (for example, in a parameter of an RMI call), using it--even with the same JavaSpaces service--may generate an IllegalArgumentException.

Specified by:

snapshot in interface GigaSpace

Parameters:

entry - The entry to snapshot

Returns:

The snapshot

Throws:

DataAccessException

See Also:

IPojoSpace.snapshot(Object)

readById

public <T> T readById(Class<T> clazz,
                      Object id)

Reads any matching entry from the space in an asynchronous manner. Returns immediately with a future. The future can then be used to check if there is a match or not. Once a match is found or the timeout expires, the future will return a result (null in case there was no match).

Note, the timeout is the default timeout this interface is configured with (using its factory) and defaults to JavaSpace.NO_WAIT.

Specified by:

asyncRead in interface GigaSpace

Parameters:

template - The template used for matching. Matching is done against template with null fields being wildcards ("match anything") other fields being values ("match exactly on the serialized form").

Returns:

A copy of the object read from the space.

Throws:

Another possible modifier is ReadModifiers.THROW_PARTIAL_FAILURE which The modifier will cause QueryMultiplePartialFailureException to be thrown when not all of the requested number of entries are returned and one or more cluster members are not available.

Specified by:

readMultiple in interface GigaSpace

Parameters:

template - The template used for matching. Matching is done against the template with null fields being. wildcards ("match anything") other fields being values ("match exactly on the serialized form"). The template can also be one of the different Query classes

maxEntries - A limit on the number of entries to be returned. Use Integer.MAX_VALUE for the uppermost limit.

modifiers - One or a union of ReadModifiers.

Returns:

A copy of the entries read from the space.

Throws:

DataAccessException

write

public <T> LeaseContext<T> write(T entry)
                      throws DataAccessException

Description copied from interface: GigaSpace

Writes a new object to the space, returning its LeaseContext.

By default uses the UpdateModifiers.UPDATE_OR_WRITE modifier (see GigaSpace.write(Object,long,long,int). In order to force the operation to perform "write" only (a bit more performant), the UpdateModifiers.WRITE_ONLY modifier can be used resulting in an EntryAlreadyInSpaceException if the entry already exists in the space (it must have an id for this exception to be raised).

If the object has a primary key that isn't auto - generated, and the modifiers value is one of UpdateModifiers.UPDATE_OR_WRITE, UpdateModifiers.UPDATE_ONLY or UpdateModifiers.PARTIAL_UPDATE, it will call to the update method, returning a LeaseContext holder. This lease is unknown to the grantor, unless an actual 'write' was performed.

The entry will be written using the default lease this interface is configured with (using the its factory). In order to explicitly define the lease, please use GigaSpace.write(Object,long).

Specified by:

write in interface GigaSpace

Parameters:

entry - The entry to write to the space

Returns:

A usable Lease on a successful write, or null if performed with the proxy configured with NoWriteLease flag.

execute

public <T extends Serializable> AsyncFuture<T> execute(Task<T> task)

Description copied from interface: GigaSpace

Executes a task on a specific space node. The space node it will execute on should be controlled by having a method that return the routing value annotated with SpaceRouting.

In order to control the routing externally, use GigaSpace.execute(org.openspaces.core.executor.Task, Object).

The space that the task is executed within can be accessible by marking a field with type GigaSpace using the TaskGigaSpace annotation. Another option is by implementing the TaskGigaSpaceAware interface.

Resource injection can be enabled by marking the task with AutowireTask or with AutowireTaskMarker. Resources defined within processing unit (space node) the task is executed on are accessible by using either the Autowired or javax.annotation.Resource annotations (assuming they are enabled using context:annotation-config). Bean life cycle methods, such as ClusterInfoAware and ApplicationContextAware are also available.

Specified by:

execute in interface GigaSpace

Parameters:

task - The task to execute

Returns:

a Future representing pending completion of the task, and whose get() method will return the task value upon completion.

Description copied from interface: GigaSpace

Executes a task on all the nodes that correspond to the list of routing values. The task is executed on each space node with all the results reduced by the AsyncResultsReducer.reduce(java.util.List) operation.

The routing object itself does not have to be the actual routing value, but can be a POJO that defined a method annotated with @SpaceRouting annotation (this works well when wanting to use entries as the routing parameters).

The task can optionally implement AsyncResultFilter that can control if tasks should continue to accumulate or it should break and execute the reduce operation on the results received so far.

The future actual result will be the reduced result of the execution, or the exception thrown during during the reduce operation. The moderator can be used as a mechanism to listen for results as they arrive.

The last parameter can be of type AsyncFutureListener which, this case, it will be used to register a listener to be notified of the result.
