Class BasicMethodConstraints.MethodDesc

java.lang.Object
  extended by net.jini.constraint.BasicMethodConstraints.MethodDesc
All Implemented Interfaces:
Serializable
Enclosing class:
BasicMethodConstraints

public static final class BasicMethodConstraints.MethodDesc
extends Object
implements Serializable

Descriptor for specifying the constraints associated with one or more methods allowing limited wildcard matching on method names and parameter types. Methods can be specified by exact name and parameter types (matching a single method), by exact name (matching all methods with that name), by name prefix (matching all methods with names that start with that prefix), by name suffix (matching all methods with names that end with that suffix), and by a default that matches all methods.

Since:
2.0

Constructor Summary
BasicMethodConstraints.MethodDesc(InvocationConstraints constraints)
          Creates a default descriptor that matches all methods.
BasicMethodConstraints.MethodDesc(String name, Class[] types, InvocationConstraints constraints)
          Creates a descriptor that only matches methods with exactly the specified name and parameter types.
BasicMethodConstraints.MethodDesc(String name, InvocationConstraints constraints)
          Creates a descriptor that matches all methods with names that equal the specified name or that match the specified pattern, regardless of their parameter types.
 
Method Summary
 boolean equals(Object obj)
          Two instances of this class are equal if they have the same name, the same parameter types, and the same constraints.
 InvocationConstraints getConstraints()
          Returns the constraints as a non-null value.
 String getName()
          Returns the name of the method, with a prefix or suffix '*' if the name is a pattern, or null if this descriptor matches all methods.
 Class[] getParameterTypes()
          Returns the parameter types, or null if this descriptor matches all parameter types or all methods.
 int hashCode()
          Returns a hash code value for this object.
 String toString()
          Returns a string representation of this object.

Constructor Detail

BasicMethodConstraints.MethodDesc

public BasicMethodConstraints.MethodDesc(String name,
                                         Class[] types,
                                         InvocationConstraints constraints)
Creates a descriptor that only matches methods with exactly the specified name and parameter types. The constraints can be null, which is treated the same as an empty instance. The array passed to the constructor is neither modified nor retained; subsequent changes to that array have no effect on the instance created.

Parameters:
name - the name of the method
types - the formal parameter types of the method, in declared order
constraints - the constraints, or null
Throws:
NullPointerException - if name or types is null or any element of types is null
IllegalArgumentException - if name is not a syntactically valid method name

BasicMethodConstraints.MethodDesc

public BasicMethodConstraints.MethodDesc(String name,
                                         InvocationConstraints constraints)
Creates a descriptor that matches all methods with names that equal the specified name or that match the specified pattern, regardless of their parameter types. If the specified name starts with the character '*', then this descriptor matches all methods with names that end with the rest of the specified name. If the specified name ends with the character '*', then this descriptor matches all methods with names that start with the rest of the specified name. Otherwise, this descriptor matches all methods with names that equal the specified name. The constraints can be null, which is treated the same as an empty instance.

Parameters:
name - the name of the method, with a prefix or suffix '*' permitted for pattern matching
constraints - the constraints, or null
Throws:
NullPointerException - if name is null
IllegalArgumentException - if name does not match any syntactically valid method name

BasicMethodConstraints.MethodDesc

public BasicMethodConstraints.MethodDesc(InvocationConstraints constraints)
Creates a default descriptor that matches all methods. The constraints can be null, which is treated the same as an empty instance.

Parameters:
constraints - the constraints, or null
Method Detail

getName

public String getName()
Returns the name of the method, with a prefix or suffix '*' if the name is a pattern, or null if this descriptor matches all methods.

Returns:
the name of the method, with a prefix or suffix '*' if the name is a pattern, or null if this descriptor matches all methods

getParameterTypes

public Class[] getParameterTypes()
Returns the parameter types, or null if this descriptor matches all parameter types or all methods. Returns a new non-null array every time it is called.

Returns:
the parameter types, or null if this descriptor matches all parameter types or all methods

getConstraints

public InvocationConstraints getConstraints()
Returns the constraints as a non-null value.

Returns:
the constraints as a non-null value

hashCode

public int hashCode()
Returns a hash code value for this object.

Overrides:
hashCode in class Object

equals

public boolean equals(Object obj)
Two instances of this class are equal if they have the same name, the same parameter types, and the same constraints.

Overrides:
equals in class Object

toString

public String toString()
Returns a string representation of this object.

Overrides:
toString in class Object
