Method Details

getAsSQLQuery

public DataSourceSQLQuery getAsSQLQuery()

Description copied from interface: DataSourceQuery

Gets the prepared SQL representation of this query.
DataSourceQuery.supportsAsSQLQuery() return value should be checked before calling this method otherwise an UnsupportedOperationException will be thrown if the operation is not supported.

Specified by:

getAsSQLQuery in interface DataSourceQuery

Returns:

Prepared SQL representation this query.

getTemplateAsObject

public Object getTemplateAsObject()

Description copied from interface: DataSourceQuery

Gets an object representation of this query.
DataSourceQuery.supportsTemplateAsObject() return value should be checked before calling this method otherwise an UnsupportedOperationException will be thrown if the operation is not supported.

Specified by:

getTemplateAsObject in interface DataSourceQuery

Returns:

Object representation of this query.

getTemplateAsDocument

public SpaceDocument getTemplateAsDocument()

Description copied from interface: DataSourceQuery

Gets a SpaceDocument representation of this query.
DataSourceQuery.supportsTemplateAsDocument() return value should be checked before calling this method otherwise an UnsupportedOperationException will be thrown if the operation is not supported.

Specified by:

getTemplateAsDocument in interface DataSourceQuery

Returns:

SpaceDocument representation of this query.

supportsAsSQLQuery

public boolean supportsAsSQLQuery()

Specified by:

supportsAsSQLQuery in interface DataSourceQuery

Returns:

Whether this query has an SQL query representation.

supportsTemplateAsObject

public boolean supportsTemplateAsObject()

Specified by:

supportsTemplateAsObject in interface DataSourceQuery

Returns:

Whether this query has an Object representation.

supportsTemplateAsDocument

public boolean supportsTemplateAsDocument()

Specified by:

supportsTemplateAsDocument in interface DataSourceQuery

Returns:

Whether this query has a SpaceDocument representation.

getBatchSize

public int getBatchSize()

Description copied from interface: DataSourceQuery

The value returned from this method can serve as a hint for the data source implementation which indicates the batch size to be used in SpaceDataSource.getDataIterator(DataSourceQuery) method implementation (if such data source supports batching). One should use this value with care since it might return Integer.MAX_VALUE if the batch operation executed had a request for unlimited results.

Specified by:

getBatchSize in interface DataSourceQuery

Returns:

Batch size hint.

getTypeDescriptor

public SpaceTypeDescriptor getTypeDescriptor()

Specified by:

getTypeDescriptor in interface DataSourceQuery

Returns:

The SpaceTypeDescriptor representing the type this query is for.

toString

public String toString()

Overrides:

toString in class Object
