SwitchBuilder
public SwitchBuilder(int[] match, InstructionHandle[] targets, InstructionHandle target, int max_gap) 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.- Parameter:
match
- array of match values (case 2: ... case 7: ..., etc.)targets
- the instructions to be branched to for each casetarget
- the default targetmax_gap
- maximum gap that may between case branches
