Method Detail

prepareAttributes

public void prepareAttributes()
                       throws TransformerConfigurationException

Description copied from class: StyleElement

Set the attribute list for the element. This is called to process the attributes (note the distinction from processAttributes in the superclass). Must be supplied in a subclass

Specified by:

prepareAttributes in class StyleElement

Throws:

TransformerConfigurationException

validate

public void validate()
              throws TransformerConfigurationException

Description copied from class: StyleElement

Check that the element is valid. This is called once for each element, after the entire tree has been built. As well as validation, it can perform first-time initialisation. The default implementation does nothing; it is normally overriden in subclasses.

Overrides:

validate in class StyleElement

Throws:

TransformerConfigurationException

preprocess

public void preprocess()
                throws TransformerConfigurationException

Description copied from class: StyleElement

Default preprocessing method does nothing. It is implemented for those top-level elements that can be evaluated before the source document is available, for example xsl:key, xsl:attribute-set, xsl:template, xsl:locale

Overrides:

preprocess in class StyleElement

Throws:

TransformerConfigurationException

process

public void process(Context c)

Description copied from class: StyleElement

Process: called to do the real work of this stylesheet element. This method must be implemented in each subclass.

Specified by:

process in class StyleElement

Parameters:

c - The context in the source XML document, giving access to the current node, the current variables, etc.

getJavaClass

public Class getJavaClass(String uri)
                   throws TransformerException

Get the Java class, if this XSLScript element matches the specified URI. Otherwise return null

Throws:

TransformerException

getSequenceNumber

protected final long getSequenceNumber()

Get the node sequence number (in document order). Sequence numbers are monotonic but not consecutive. In the current implementation, parent nodes (elements and roots) have a zero least-significant word, while namespaces, attributes, text nodes, comments, and PIs have the top word the same as their owner and the bottom half reflecting their relative position.

Overrides:

getSequenceNumber in class NodeImpl

hasChildNodes

public final boolean hasChildNodes()

Determine if the node has any children.

Specified by:

hasChildNodes in interface NodeInfo

Specified by:

hasChildNodes in interface Node

Overrides:

hasChildNodes in class NodeImpl

Returns:

true if the node has any children, false if the node has no children.

enumerateChildren

public final AxisEnumeration enumerateChildren(NodeTest test)

Get an enumeration of the children of this node

getFirstChild

public final Node getFirstChild()

Get the first child node of the element

Specified by:

getFirstChild in interface Node

Overrides:

getFirstChild in class NodeImpl

Returns:

the first child node of the required type, or null if there are no children

getLastChild

public final Node getLastChild()

Get the last child node of the element

Specified by:

getLastChild in interface Node

Overrides:

getLastChild in class NodeImpl

Returns:

the last child of the element, or null if there are no children

getChildNodes

public final NodeList getChildNodes()

Return a NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes.

Specified by:

getChildNodes in interface Node

Overrides:

getChildNodes in class NodeImpl

getNthChild

protected final NodeImpl getNthChild(int n)

Get the nth child node of the element (numbering from 0)

Returns:

the last child of the element, or null if there is no n'th child

getStringValue

public String getStringValue()

Return the string-value of the node, that is, the concatenation of the character content of all descendent elements and text nodes.

Returns:

the accumulated character content of the element, including descendant elements.

copyStringValue

public void copyStringValue(Outputter out)
                     throws TransformerException

Copy the string-value of this node to a given outputter

Specified by:

copyStringValue in interface NodeInfo

Overrides:

copyStringValue in class AbstractNode

Throws:

TransformerException

useChildrenArray

public void useChildrenArray(NodeImpl[] array)

Supply an array to be used for the array of children. For system use only.

addChild

public void addChild(NodeImpl node,
            int index)

Add a child node to this node. For system use only. Note: normalizing adjacent text nodes is the responsibility of the caller.

removeChild

public void removeChild(int index)

Remove node at given index. Will always be followed by a renumberChildren().

renumberChildren

public void renumberChildren()

Renumber the children of a given parent node. For system use only

dropChildren

public void dropChildren()

Drop a branch of the tree. The target element remains in the tree, but its children are disconnected from the parent. Unless there are other references to the children (e.g. in a variable) they will be deleted from memory next time the garbage collector comes round.

compact

public void compact(int size)

Compact the space used by this node

getNodeValue

public String getNodeValue()

Get the node value as defined in the DOM. This is not the same as the XPath string-value.

Specified by:

getNodeValue in interface Node

Overrides:

getNodeValue in class AbstractNode
