public boolean hasLastCall()

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.hasLastCall.

Returns true if this expressions contains a call to last()

hasPositionCallback to summary
public boolean hasPositionCall()

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.hasPositionCall.

Returns true if this expressions contains a call to position(). This is needed for context changes in node steps containing multiple predicates.

public boolean hasReferenceArgs()
setParserback to summary
public void setParser(Parser parser)

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.setParser.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.setParser.

Set this node's parser. The parser (the XSLT parser) gives this syntax tree node access to the symbol table and XPath parser.

toStringback to summary
public String toString()

Implements abstract com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.
