DefaultProcessingInstruction

public DefaultProcessingInstruction(String target,
                                    Map 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 values for the PI

DefaultProcessingInstruction

public DefaultProcessingInstruction(String target,
                                    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 values for the PI

DefaultProcessingInstruction

public DefaultProcessingInstruction(Element parent,
                                    String target,
                                    String values)

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

Parameters:

parent - is the parent element

target - is the name of the PI

values - is the values for the PI

setTarget

public void setTarget(String target)

Description copied from interface: ProcessingInstruction

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

Specified by:

setTarget in interface ProcessingInstruction

Overrides:

setTarget in class FlyweightProcessingInstruction

setText

public void setText(String text)

Description copied from interface: Node

Sets the text data of this node or this method will throw an UnsupportedOperationException if it is read-only.

Specified by:

setText in interface Node

Overrides:

setText in class AbstractNode

setValues

public void setValues(Map values)

Specified by:

setValues in interface ProcessingInstruction

Overrides:

setValues in class AbstractProcessingInstruction

setValue

public void setValue(String name,
                     String value)

Specified by:

setValue in interface ProcessingInstruction

Overrides:

setValue in class AbstractProcessingInstruction

getParent

public Element getParent()

Description copied from interface: Node

getParent returns the parent Element if this node supports the parent relationship or null if it is the root element or does not support the parent relationship.

This method is an optional feature and may not be supported for all Node implementations.

Specified by:

getParent in interface Node

Overrides:

getParent in class AbstractNode

setParent

public void setParent(Element parent)

Description copied from interface: Node

setParent sets the parent relationship of this node if the parent relationship is supported or does nothing if the parent relationship is not supported.

This method should only be called from inside an Element implementation method and is not intended for general use.

Specified by:

setParent in interface Node

Overrides:

setParent in class AbstractNode

supportsParent

public boolean supportsParent()

Description copied from interface: Node

supportsParent returns true if this node supports the parent relationship.

Some XML tree implementations are singly linked and only support downward navigation through children relationships. The default case is that both parent and children relationships are supported though for memory and performance reasons the parent relationship may not be supported.

Specified by:

supportsParent in interface Node

Overrides:

supportsParent in class AbstractNode

isReadOnly

public boolean isReadOnly()

Description copied from interface: Node

isReadOnly returns true if this node is read only and cannot be modified. Any attempt to modify a read-only Node will result in an UnsupportedOperationException being thrown.

Specified by:

isReadOnly in interface Node

Overrides:

isReadOnly in class AbstractNode
