Direct Known Subclasses:

ElemCallTemplate

public class ElemForEach

extends ElemTemplateElement

Implement xsl:for-each.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.

Field Detail

m_doc_cache_off

public boolean m_doc_cache_off

This is set by an "xalan:doc-cache-off" pi. It tells the engine that documents created in the location paths executed by this element will not be reparsed. It's set by StylesheetHandler during construction. Note that this feature applies _only_ to xsl:for-each elements in its current incarnation; a more general cache management solution is desperately needed.

m_selectExpression

protected Expression m_selectExpression

The "select" expression.

m_sortElems

protected java.util.Vector m_sortElems

Vector containing the xsl:sort elements associated with this element.

Constructor Detail

ElemForEach

public ElemForEach()

Construct a element representing xsl:for-each.

Method Detail

setSelect

public void setSelect(XPath xpath)

Set the "select" attribute.

Parameters:

xpath - The XPath expression for the "select" attribute.

getSelect

public Expression getSelect()

Get the "select" attribute.

Returns:

The XPath expression for the "select" attribute.

compose

public void compose(StylesheetRoot sroot)
             throws javax.xml.transform.TransformerException

This function is called after everything else has been recomposed, and allows the template to set remaining values that may be based on some other property that depends on recomposition. NEEDSDOC @param sroot
