Field Detail

DEBUG

static final boolean DEBUG

Constant Field Values

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 Vector m_sortElems

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

Constructor Detail

ElemForEach

public ElemForEach()
