Fields Summary

Constructors Summary
FCONST()
Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

public FCONST(float f)
    super(com.sun.org.apache.bcel.internal.Constants.FCONST_0, (short)1);

    if(f == 0.0)
      opcode = com.sun.org.apache.bcel.internal.Constants.FCONST_0;
    else if(f == 1.0)
      opcode = com.sun.org.apache.bcel.internal.Constants.FCONST_1;
    else if(f == 2.0)
      opcode = com.sun.org.apache.bcel.internal.Constants.FCONST_2;
    else
      throw new ClassGenException("FCONST can be used only for 0.0, 1.0 and 2.0: " + f);

    value = f;
  
Methods Summary
public voidaccept(com.sun.org.apache.bcel.internal.generic.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.
