| public java.lang.String | getEscapedName()Returns the escaped qname of the parameter
return _escapedName;
|
| public com.sun.org.apache.xalan.internal.xsltc.compiler.QName | getName()Return the name of this WithParam.

'select' attribute (this has precedence) or in the element body.

| public void | setDoParameterOptimization(boolean flag)Set the do parameter optimization flag

|
| public void | setName(com.sun.org.apache.xalan.internal.xsltc.compiler.QName name)Set the name of the variable or paremeter. Escape all special chars.

| public void | translate(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen)This code generates a sequence of bytecodes that call the
addParameter() method in AbstractTranslet. The method call will add
(or update) the parameter frame with the new parameter value.
final ConstantPoolGen cpg = classGen.getConstantPool();

|
| public void | translateValue(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen)Compile the value of the parameter, which is either in an expression in
a 'select' attribute, or in the with-param element's body
// Compile expression is 'select' attribute if present
if (_select != null) {
_select.translate(classGen, methodGen);

| public com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type | typeCheck(com.sun.org.apache.xalan.internal.xsltc.compiler.SymbolTable stable)Type-check either the select attribute or the element body, depending
on which is in use.
