Methods Summary
public abstract double	getPriority() Returns the priority of this pattern (section 5.5 in the XSLT spec).
public abstract void	translate(com.sun.org.apache.xalan.internal.xsltc.compiler.util.ClassGenerator classGen, com.sun.org.apache.xalan.internal.xsltc.compiler.util.MethodGenerator methodGen) 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 {@link com.sun.org.apache.xalan.internal.xsltc.compiler.AlternativePattern#translate()}) then a GOTO must be appended to the instruction list after calling translate.
public abstract com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type	typeCheck(com.sun.org.apache.xalan.internal.xsltc.compiler.SymbolTable stable) 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.
