Example 6 with Variable

use of org.apache.xpath.operations.Variable in project j2objc by google.

the class RedundentExprEliminator method changeToVarRef.

/**
   * Change the expression owned by the owner argument to a variable reference 
   * of the given name.
   * 
   * Warning: For global vars, this function relies on the variable declaration 
   * to which it refers having been added just prior to this function being called,
   * so that the reference index can be determined from the size of the global variables 
   * list minus one.
   * 
   * @param varName The name of the variable which will be referenced.
   * @param owner The owner of the expression which will be replaced by a variable ref.
   * @param paths The paths list that the iterator came from, mainly to determine
   *              if this is a local or global reduction.
   * @param psuedoVarRecipient The element within whose scope the variable is 
   *                           being inserted, possibly a StylesheetRoot.
