public final class MultiCstInsn extends FixedSizeInsn
An instruction with multiple constant arguments in addition to all the normal instruction information.

  • Constructor Details

    • MultiCstInsn

      public MultiCstInsn(Dop opcode, SourcePosition position, RegisterSpecList registers, Constant[] constants)
      Constructs an instance. The output address of this instance is initially unknown (-1) as is the constant pool index.
      Parameters:
      opcode - the opcode; one of the constants from Dops
      position - non-null; source position
      registers - non-null; register list, including a result register if appropriate (that is, registers may be either ins or outs)
      constants - non-null; constants argument

  • Method Details

    • withOpcode

      public DalvInsn withOpcode(Dop opcode)
      Returns an instance that is just like this one, except that its opcode is replaced by the one given, and its address is reset.
      Specified by:
      withOpcode in class DalvInsn
      Parameters:
      opcode - non-null; the new opcode
      Returns:
      non-null; an appropriately-constructed instance

    • withRegisters

      public DalvInsn withRegisters(RegisterSpecList registers)
      Returns an instance that is just like this one, except that the register list is replaced by the given one, and its address is reset.
      Specified by:
      withRegisters in class DalvInsn
      Parameters:
      registers - non-null; new register list
      Returns:
      non-null; an appropriately-constructed instance

    • getNumberOfConstants

      public int getNumberOfConstants()
      Gets the number of constants associated with instruction.
      Returns:
      the number of constants.

    • getConstant

      public Constant getConstant(int position)
      Gets a constant associated with the instruction.
      Parameters:
      position - the position of the constant to get.
      Returns:
      non-null; the constant argument

    • getIndex

      public int getIndex(int position)
      Gets the DEX index of a constant. It is only valid to call this after setIndex(int, int) has been called.
      Parameters:
      position - the position of the constant to get the index for.
      Returns:
      >= 0; the constant pool index

    • hasIndex

      public boolean hasIndex(int position)
      Returns whether the DEX index of a constant has been set.
      Parameters:
      position - the position of the constant to test.
      Returns:
      true if the index has been set
      See Also:

    • setIndex

      public void setIndex(int position, int index)
      Sets the DEX index of a constant. It is only valid to call this method once per instance.
      Parameters:
      position - the position of the constant to set.
      index - index >= 0; the constant pool index

    • getClassIndex

      public int getClassIndex()
      Gets the class index associated with this instance. The class index may be set only once and for one of the constants associated with this instance (e.g. a CstMethodRef). It is only valid to call this after setClassIndex(int) has been called.
      Returns:
      >= 0; the constant pool index of the class.

    • hasClassIndex

      public boolean hasClassIndex()
      Returns whether the class index associated with this instruction has been set.
      Returns:
      true if the index has been set, false otherwise
      See Also:

    • setClassIndex

      public void setClassIndex(int index)
      Sets the class index associated with this instruction. This is the constant pool index for the class referred to by this instruction. Only reference constants have a class, so it is only on instances with reference constants that this method should ever be called. It is only valid to call this method once per instance.
      Parameters:
      index - index >= 0; the constant pool index of the class

    • argString

      protected String argString()
      Gets the string form for any arguments to this instance. Subclasses must override this.
      Specified by:
      argString in class DalvInsn
      Returns:
      null-ok; the string version of any arguments or null if there are none

    • cstString

      public String cstString()
      Helper which returns the string form of the associated constants for inclusion in a human oriented listing dump. This method is only implemented for instructions with one or more constants.
      Overrides:
      cstString in class DalvInsn
      Returns:
      the constant as a string.

    • cstComment

      public String cstComment()
      Helper which returns the comment form of the associated constants for inclusion in a human oriented listing dump. This method is only implemented for instructions with one or more constants.
      Overrides:
      cstComment in class DalvInsn
      Returns:
      the comment as a string.
