offset
private final int[] offset
- Stores the code offsets.
bytecode_index
private final int[] bytecode_index
- Stores the bytecode indices.
jq_BytecodeMap
public jq_BytecodeMap(int[] offset,
int[] bytecode_index)
- Constructs a new bytecode map, using the given code offset and bytecode index array.
The two arrays are co-indexed. Each entry in the code offset array corresponds
to an inclusive start offset of the instructions corresponding to the bytecode index
in the co-indexed bytecode array.
The length of the two arrays must be equal.
getBytecodeIndex
public int getBytecodeIndex(int off)
- Returns the bytecode index corresponding to the given code offset, or -1 if the
offset is out of range.
