adjustSeekIndex method

int adjustSeekIndex(
  1. int i
)

Allowed derived classes to modify the behavior of operations which change the current stream position by adjusting the target token index of a seek operation. The default implementation simply returns i. If an exception is thrown in this method, the current stream index should not be changed.

For example, [CommonTokenStream] overrides this method to ensure that the seek target is always an on-channel token.

@param i The target token index. @return The adjusted target token index.

Implementation

int adjustSeekIndex(int i) {
  return i;
}
