Constructor Detail

ProxyCacheLogicalTargets

public ProxyCacheLogicalTargets()

Constructor of ProxyCacheLogicalTargets.

Method Detail

add

public void add(ProxyCacheManagement logicalTarget)

Appends the specific logical target to the list of logical targets.

Parameters:

logicalTarget - logical target to be appended to the list.

getByTID

public ProxyCacheManagement getByTID(java.lang.String tid)

Gets a logical target from the list. The logical target is idenfied by the target identifier (tid).

NOTICE: elmentents are not copied. Their reference is passed.

Parameters:

tid - definition in TargetField.target.

Returns:

an object which contains the logical target information. If the tid is not in the list, it returns null

getByTarget

public ProxyCacheManagement getByTarget(java.lang.String target)

Gets a logical target from the list. The logical target is idenfied by the target.

NOTICE: elmentents are not copied. Its reference is returned.

Parameters:

target - definition in TargetField.target.

Returns:

an object which contains the logical target information. If the target is not in the list, it returns null

getTarget

public ProxyCacheManagement getTarget(java.lang.String target,
                                      java.lang.String tid)

Gets a logical target from the list. The logical target is idenfied by the target and/or tid. If the target and tid parameters do not identify the same target an exception is thrown.

Parameters:

target - definition in TargetField.target.

tid - definition in TargetField.target.

Returns:

an object which contains the logical target information. If the target is not in the list, it returns null

equals

public boolean equals(java.lang.String target,
                      java.lang.String tid)

Check if the logical target identified

Parameters:

target - definition in TargetField.target.

tid - definition in TargetField.tid.

Returns:

true if the target belongs to the target identifier tid.

isEmpty

public boolean isEmpty()

Returns true if the list contains no elements. Otherwise, returns false.

Returns:

true if the list contains no elements.

size

public int size()

Returns the number of elements in the list.

Returns:

the number of elements in the list.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

list

public void list(java.io.PrintStream out)

Prints this Logical Target List fields out to the specified output stream. This method is useful for debugging.

Parameters:

out - an output stream.
