Method Detail

setParser

public void setParser(Parser parser)

Description copied from class: SyntaxTreeNode

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

Overrides:

setParser in class SyntaxTreeNode

Parameters:

parser - The XSLT parser.

typeCheck

public Type typeCheck(SymbolTable stable)
               throws TypeCheckError

Description copied from class: Pattern

Returns the type of a pattern, which is always a NodeType. A NodeType has a number of subtypes defined by NodeType._type corresponding to each type of node.

Overrides:

typeCheck in class LocationPathPattern

Parameters:

stable - The compiler/parser's symbol table

Throws:

TypeCheckError

isWildcard

public boolean isWildcard()

Specified by:

isWildcard in class LocationPathPattern

getKernelPattern

public StepPattern getKernelPattern()

Specified by:

getKernelPattern in class LocationPathPattern

reduceKernelPattern

public void reduceKernelPattern()

Specified by:

reduceKernelPattern in class LocationPathPattern

translate

public void translate(ClassGenerator classGen,
                      MethodGenerator methodGen)

Description copied from class: Pattern

Translate this node into JVM bytecodes. Patterns are translated as boolean expressions with true/false lists. Before calling translate on a pattern, make sure that the node being matched is on top of the stack. After calling translate, make sure to backpatch both true and false lists. True lists are the default, in the sense that they always "fall through". If this is not the intended semantics (e.g., see AlternativePattern.translate(org.apache.xalan.xsltc.compiler.util.ClassGenerator, org.apache.xalan.xsltc.compiler.util.MethodGenerator)) then a GOTO must be appended to the instruction list after calling translate.

Overrides:

translate in class LocationPathPattern

Parameters:

classGen - BCEL Java class generator

methodGen - BCEL Java method generator

toString

public java.lang.String toString()

Overrides:

toString in class LocationPathPattern
