Examples of org.objectweb.asm.commons.GeneratorAdapter.ifZCmp()

org.objectweb.asm.commons.GeneratorAdapter.ifZCmp()
Generates the instructions to jump to a label based on the comparison of the top integer stack value with zero. @param mode how these values must be compared. One of EQ, NE, LT, GE, GT,LE. @param label where to jump if the comparison result is true.
