Constructor Detail

DefaultText

public DefaultText(java.lang.String text)

DOCUMENT ME!

Parameters:

text - is the Text text

DefaultText

public DefaultText(Element parent,
                   java.lang.String text)

DOCUMENT ME!

Parameters:

parent - is the parent element

text - is the Text text

Method Detail

setText

public void setText(java.lang.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

Parameters:

text - is the new textual value of this node

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

Returns:

the parent of this node or null if it is the root of the tree or the parent relationship is not supported.

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

Parameters:

parent - is the new parent of this node.

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

Returns:

true if this node supports the parent relationship or false it is not supported

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

Returns:

true if this Node is read only and cannot be modified otherwise false.
