All Implemented Interfaces:

Serializable, Cloneable, Node, ProcessingInstruction

Direct Known Subclasses:

DefaultProcessingInstruction

public class FlyweightProcessingInstruction
extends AbstractProcessingInstruction

FlyweightProcessingInstruction is a Flyweight pattern implementation of a singly linked, read-only XML Processing Instruction.

This node could be shared across documents and elements though it does not support the parent relationship.

Constructor Details

FlyweightProcessingInstruction

public FlyweightProcessingInstruction()

A default constructor for implementors to use.

FlyweightProcessingInstruction

public FlyweightProcessingInstruction(String target,
 Map<String,String> values)

This will create a new PI with the given target and values

Parameters:

target - is the name of the PI

values - is the Map of the values for the PI

FlyweightProcessingInstruction

public FlyweightProcessingInstruction(String target,
 String text)

This will create a new PI with the given target and values

Parameters:

target - is the name of the PI

text - is the values for the PI as text

Method Details

Returns:

the target of this PI

setTarget

public void setTarget(String target)

Description copied from interface: ProcessingInstruction

This method is the equivalent to the Node.setName(String)method. It is added for clarity.

Parameters:

target - DOCUMENT ME!

getText

public String getText()

Description copied from interface: Node

Returns the text of this node.

Specified by:

getText in interface Node

Specified by:

getText in interface ProcessingInstruction

Overrides:
