  • Method Details

    • getPointerKeyForLocal

      PointerKey getPointerKeyForLocal(CGNode node, int valueNumber)
      Returns:
      the PointerKey that acts as a representative for the class of pointers that includes the local variable identified by the value number parameter.

    • getFilteredPointerKeyForLocal

      FilteredPointerKey getFilteredPointerKeyForLocal(CGNode node, int valueNumber, FilteredPointerKey.TypeFilter filter)
      Returns:
      the PointerKey that acts as a representative for the class of pointers that includes the local variable identified by the value number parameter.

    • getPointerKeyForReturnValue

      PointerKey getPointerKeyForReturnValue(CGNode node)
      Returns:
      the PointerKey that acts as a representative for the class of pointers that includes the return value for a node

    • getPointerKeyForExceptionalReturnValue

      PointerKey getPointerKeyForExceptionalReturnValue(CGNode node)
      Returns:
      the PointerKey that acts as a representative for the class of pointers that includes the exceptional return value

    • getPointerKeyForStaticField

      PointerKey getPointerKeyForStaticField(IField f)
      Returns:
      the PointerKey that acts as a representative for the class of pointers that includes the contents of the static field

    • getPointerKeyForInstanceField

      PointerKey getPointerKeyForInstanceField(InstanceKey I, IField field)
      Returns:
      the PointerKey that acts as a representation for the class of pointers that includes the given instance field.

    • getPointerKeyForArrayContents

      PointerKey getPointerKeyForArrayContents(InstanceKey I)
      TODO: expand this API to differentiate between different array indices
      Parameters:
      I - an InstanceKey representing an abstract array
      Returns:
      the PointerKey that acts as a representation for the class of pointers that includes the given array contents.
