Examples of org.objectweb.asm.MethodVisitor.visitLookupSwitchInsn()

org.objectweb.asm.MethodVisitor.visitLookupSwitchInsn()
Visits a LOOKUPSWITCH instruction. @param dflt beginning of the default handler block. @param keys the values of the keys. @param labels beginnings of the handler blocks. labels[i] isthe beginning of the handler block for the keys[i] key.
