      Returns this Value as a DoubleValue.

    • referenceValue

      public ReferenceValue referenceValue()
      Returns this Value as a ReferenceValue.

    • instructionOffsetValue

      public InstructionOffsetValue instructionOffsetValue()
      Returns this Value as an InstructionOffsetValue.

    • isSpecific

      public boolean isSpecific()
      Returns whether this Value represents a single specific (but possibly unknown) value.

    • isParticular

      public boolean isParticular()
      Returns whether this Value represents a single particular (known) value.

    • generalize

      public abstract Value generalize(Value other)
      Returns the generalization of this Value and the given other Value.

    • isCategory2

      public abstract boolean isCategory2()
      Returns whether the computational type of this Value is a category 2 type. This means that it takes up the space of two category 1 types on the stack, for instance.

    • computationalType

      public abstract int computationalType()
      Returns the computational type of this Value.
      返回:
      TYPE_INTEGER, TYPE_LONG, TYPE_FLOAT, TYPE_DOUBLE, TYPE_REFERENCE, or TYPE_INSTRUCTION_OFFSET.

    • internalType

      public abstract String internalType()
      Returns the internal type of this Value.
      返回:
      TypeConstants.BOOLEAN, TypeConstants.BYTE, TypeConstants.CHAR, TypeConstants.SHORT, TypeConstants.INT , TypeConstants.LONG, TypeConstants.FLOAT, TypeConstants.DOUBLE, TypeConstants.CLASS_START ... TypeConstants.CLASS_END , or an array type containing any of these types (always as String).

    • copyIfMutable

      public Value copyIfMutable()
      Returns a deep copy of the value if it mutable, returns the value itself otherwise.
