Detailed Description

SWITCH - Branch depending on int value, generates either LOOKUPSWITCH or TABLESWITCH instruction, depending on whether the match values (int[]) can be sorted with no gaps between the numbers.

Constructor & Destructor Documentation

SWITCH::SWITCH (  int   match[], InstructionHandle   targets[], InstructionHandle   target, int   max_gap )  [inline]

Template for switch() constructs. If the match array can be sorted in ascending order with gaps no larger than max_gap between the numbers, a TABLESWITCH instruction is generated, and a LOOKUPSWITCH otherwise. The former may be more efficient, but needs more space. Note, that the key array always will be sorted, though we leave the original arrays unaltered. Parameters: match   array of match values (case 2: ... case 7: ..., etc.) targets   the instructions to be branched to for each case target   the default target max_gap   maximum gap that may between case branches Definition at line 36 of file lib/jpf/de/fub/bytecode/generic/SWITCH.java.
