public void setDescendantAxis()
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.

translateback to summary
public void translate(ClassGenerator classGen, MethodGenerator methodGen)

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

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Expression.translate.

Translate this node into JVM bytecodes.

typeCheckback to summary
public Type typeCheck(SymbolTable stable) throws TypeCheckError

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

Type check a FilterParentPath. If the filter is not a node-set add a cast to node-set only if it is of reference type. This type coercion is needed for expressions like $x/LINE where $x is a parameter reference.
