Method Detail

• useObjectCatalog

  protected abstract boolean useObjectCatalog()

  should we maintain an object catalog for each instance key, storing the names of all known properties of the instance key? required to handle EachElementGetInstructions.

  AstSSAPropagationCallGraphBuilder.AstConstraintVisitor.visitPut(SSAPutInstruction), AstSSAPropagationCallGraphBuilder.AstConstraintVisitor.visitEachElementGet(EachElementGetInstruction)

• isUncataloguedField

  protected boolean isUncataloguedField(IClass type,
                                        String fieldName)

  each language can specify whether a particular field name should be stored in object catalogs or not. By default, always return false.

• makeVisitor

  public SSAPropagationCallGraphBuilder.ConstraintVisitor makeVisitor(CGNode node)

  Overrides:

  a visitor to examine instructions in the ir

• fieldKeyForUnknownWrites

  protected abstract AbstractFieldPointerKey fieldKeyForUnknownWrites(AbstractFieldPointerKey fieldKey)

  If the given fieldKey represents a concrete field, return the corresponding field key that represents all writes to unknown fields that could potentially alias fieldKey

• sameMethod

  protected abstract boolean sameMethod(CGNode opNode,
                                        String definingMethod)

  Is definingMethod the same as the method represented by opNode? We need this since the names for methods in some languages don't map in the straightforward way to the CGNode
