Constructor Detail

ExprWalker

public ExprWalker(Map pNamespaceMap,
                  Map pFunctionMap,
                  String pRicebridgePrefix,
                  boolean pNamespaceAware)

Create an ExprWalker with specified settings originally from XmlSpec.

Method Detail

makePaths

public List makePaths(com.ricebridge.xmlman.tp.expr.Expr pExpr,
                      boolean pSplitOnDescend)

Create the TargetPath list.

Splitting the TargetPaths on descend parts allows the preceding parts to continue matching.

Parameters:

pExpr - Jaxen expression

pSplitOnDescend - split TargetPaths that contain descend parts

walkExpr

public void walkExpr(com.ricebridge.xmlman.tp.expr.Expr pExpr,
                     boolean pTopLevel)

Start walking at the top.

walkExpr

public void walkExpr(com.ricebridge.xmlman.tp.expr.Expr pExpr,
                     Condition pCondition)

walkExpr

public void walkExpr(com.ricebridge.xmlman.tp.expr.Expr pExpr,
                     boolean pTopLevel,
                     boolean pTargetIsXml,
                     Condition pCondition)

Generic expression handler.

walkLocationPath

public void walkLocationPath(com.ricebridge.xmlman.tp.expr.LocationPath pLocationPath,
                             boolean pTopLevel,
                             boolean pTargetIsXml,
                             Condition pCondition)

Walk a location path - this creates a TargetPath.

walkNameStep

public void walkNameStep(com.ricebridge.xmlman.tp.expr.NameStep pNameStep,
                         int pAxis)

Handle a generic name step.

walkPredicates

public void walkPredicates(com.ricebridge.xmlman.tp.expr.Predicated pPredicated,
                           PathPart pPathPart)

Dive into the predicate expressions.
