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

Returns the priority of this pattern (section 5.5 in the XSLT spec).

public Template getTemplate()

Overrides com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.getTemplate.

Doc from com.sun.org.apache.xalan.internal.xsltc.compiler.SyntaxTreeNode.getTemplate.

Get the Template node that represents the <xsl:template/> element that this node occured under. Note that this method will return 'null' for nodes that represent top-level elements.

Returns:Template

The Template ancestor node of this node or 'null'.

isWildcardback to summary
public abstract boolean isWildcard()
noSmallerThanback to summary
public boolean noSmallerThan(LocationPathPattern other)

This method is used by the Mode class to prioritise patterns and template. This method is called for templates that are in the same mode and that match on the same core pattern. The rules used are: o) first check precedence - highest precedence wins o) then check priority - highest priority wins o) then check the position - the template that occured last wins

reduceKernelPatternback to summary
public abstract void reduceKernelPattern()
setTemplateback to summary
public void setTemplate(final Template template)
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.

Returns:String

a string representation of the object

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

Implements abstract com.sun.org.apache.xalan.internal.xsltc.compiler.Pattern.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.

Parameters
classGen:ClassGenerator

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

BCEL Java class generator

methodGen:MethodGenerator

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

BCEL Java method generator

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

Implements abstract com.sun.org.apache.xalan.internal.xsltc.compiler.Pattern.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.

Parameters
stable:SymbolTable

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

The compiler/parser's symbol table
