Method Detail

insertionIndex
```
public static int insertionIndex(int[] pcToSourceMap,
                 int length,
                 int pc)
```
This methods searches for an existing entry inside the pcToSourceMap table with a pc equals to @pc. If there is an existing entry it returns -1 (no insertion required). Otherwise it returns the index where the entry for the pc has to be inserted. This is based on the fact that the pcToSourceMap table is sorted according to the pc.

Parameters:
pcToSourceMap - the given pcToSourceMap array
length - the given length
pc - the given pc

Returns:
int
