## Class DCONST

- java.lang.Object
- - org.apache.bcel.generic.Instruction
  - - org.apache.bcel.generic.DCONST

- All Implemented Interfaces:
    Cloneable, ConstantPushInstruction, PushInstruction, StackProducer, TypedInstruction

      public class DCONST
      extends Instruction
      implements ConstantPushInstruction

  DCONST - Push 0.0 or 1.0, other values cause an exception

      Stack: ... -> ...,

- - ### Constructor Detail

    - #### DCONST

          public DCONST(double f)

  - ### Method Detail

    - #### getValue

          public Number getValue()

      Specified by:
        `getValue` in interface `ConstantPushInstruction`

    - #### getType

          public Type getType(ConstantPoolGen cp)

      Specified by:
        `getType` in interface `TypedInstruction`
      Returns:
        Type.DOUBLE

    - #### accept

          public void accept(Visitor v)

      Call corresponding visitor method(s). The order is: Call visitor methods of implemented interfaces first, then call methods according to the class hierarchy in descending order, i.e., the most specific visitXXX() call comes last.
      Specified by:
        `accept` in class `Instruction`
      Parameters:
        `v` - Visitor object
