List of produceStack() Examples

Examples of produceStack()

org.apache.bcel.generic.Instruction.produceStack()
This method also gives right results for instructions whose effect on the stack depends on the constant pool entry they reference. @return Number of words produced onto stack by this instruction,or Constants.UNPREDICTABLE, if this can not be computed statically
