Constructor Detail

JDOMFacadeHelper

public JDOMFacadeHelper()

Method Detail

getIDOMNode

public static IDOMNode getIDOMNode(JNode node)

reset

public void reset()

Overrides:

reset in class FacadeHelper

getJDOMFactory

protected DOMFactory getJDOMFactory()

setForcedSourceCompatibility

public void setForcedSourceCompatibility(boolean forcedSourceCompatibility)

isForcedSourceCompatibility

public boolean isForcedSourceCompatibility()

adjustSourceCompatibility

protected void adjustSourceCompatibility(java.lang.String value)

createCompilationUnit

public JCompilationUnit createCompilationUnit(java.lang.String name,
                                              java.lang.String contents)

Specified by:

createCompilationUnit in class FacadeHelper

getOriginalContents

public java.lang.String getOriginalContents(JCompilationUnit compilationUnit)

Description copied from class: FacadeHelper

Returns the original, unmodified, content of the compilation unit. Not all facade implementation may be able to provide this information.

Overrides:

getOriginalContents in class FacadeHelper

Returns:

the original contents or null

doConvertToNode

protected JNode doConvertToNode(java.lang.Object object)

Specified by:

doConvertToNode in class FacadeHelper

getContext

public java.lang.Object getContext(JNode node)

Description copied from class: FacadeHelper

Returns the context of a node. The context is usually an object that would be used to create a child or sibling of the node.

Specified by:

getContext in class FacadeHelper

Returns:

the context of a node.

cloneNode

public JNode cloneNode(java.lang.Object context,
                       JNode node)

Description copied from class: FacadeHelper

Clones the specified node, returning an object that is related to the given context. On some implementations the context may be null.

Specified by:

cloneNode in class FacadeHelper

Returns:

a cloned version of the specified node

addChild

public boolean addChild(JNode node,
                        JNode child)

Description copied from class: FacadeHelper

Adds the given orphan node (document fragment) as the last child of the specified node.

Overrides:

addChild in class FacadeHelper

Parameters:

node - the parent of the child to be added

child - the new child node

Returns:

whether the operation was successful.

See Also:

FacadeHelper.insertSibling(JNode, JNode, boolean), FacadeHelper.remove(JNode)

insertSibling

public boolean insertSibling(JNode node,
                             JNode sibiling,
                             boolean before)

Description copied from class: FacadeHelper

Inserts the given orphan node as a sibling of the specified node, immediately before or after it.

Overrides:

insertSibling in class FacadeHelper

Parameters:

node - the node that will be after the new sibling

sibiling - the new sibling node

before - whether the sibling should be added before the node

See Also:

FacadeHelper.addChild(JNode, JNode), FacadeHelper.remove(JNode)

remove

public boolean remove(JNode node)

Description copied from class: FacadeHelper

Separates the specified node from its parent and siblings, maintaining any ties that this node has to the underlying document fragment. A document fragment that is removed from its host document may still be dependent on that host document until it is inserted into a different document. Removing a root node has no effect.

Overrides:

remove in class FacadeHelper

Parameters:

node - the node to be removed

Returns:

whether the operation was successful.

See Also:

FacadeHelper.addChild(JNode, JNode), FacadeHelper.insertSibling(JNode, JNode, boolean)

getFirstChild

public JNode getFirstChild(JNode node)

Description copied from class: FacadeHelper

Returns the first child of the specified node. Children appear in the order in which they exist in the source code.

Overrides:

getFirstChild in class FacadeHelper

Returns:

the first child, or null if this node has no children

See Also:

FacadeHelper.getChildren(JNode, Class)

getPrevious

public JNode getPrevious(JNode node)

Description copied from class: FacadeHelper

Returns the sibling node immediately preceding the specified node.

Overrides:

getPrevious in class FacadeHelper

Returns:

the previous node, or null if there is no preceding node

getNext

public JNode getNext(JNode node)

Description copied from class: FacadeHelper

Returns the sibling node immediately following the specified node.

Overrides:

getNext in class FacadeHelper

Returns:

the next node, or null if there is no following node

Returns:

boolean

isSibilingTraversalExpensive

public boolean isSibilingTraversalExpensive()

Description copied from class: FacadeHelper

Returns whether using the FacadeHelper.getPrevious(JNode) and FacadeHelper.getNext(JNode) methods is slower than using JNode.getChildren() directly.
