Fields Summary
private int
value
Constructors Summary
ICONST()
Empty constructor needed for the Class.newInstance() statement in Instruction.readInstruction(). Not to be used otherwise.

public ICONST(int i)

    super(com.sun.org.apache.bcel.internal.Constants.ICONST_0, (short)1);

    if((i >= -1) && (i <= 5))
      opcode = (short)(com.sun.org.apache.bcel.internal.Constants.ICONST_0 + i); // Even works for i == -1
    else
      throw new ClassGenException("ICONST can be used only for value between -1 and 5: " +
				  i);
    value = i;
  
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.
