Examples of org.ow2.asm.MethodVisitor.visitTableSwitchInsn()

org.ow2.asm.MethodVisitor.visitTableSwitchInsn()
Visits a TABLESWITCH instruction. @param min the minimum key value. @param max the maximum key value. @param dflt beginning of the default handler block. @param labels beginnings of the handler blocks. labels[i] isthe beginning of the handler block for the min + i key.

        // tableswitch
