toStringback to summary
public String toString()

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

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

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 com.sun.org.apache.xalan.internal.xsltc.compiler.AlternativePattern#translate) then a GOTO must be appended to the instruction list after calling translate.

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

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

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.Pattern.typeCheck.

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.
