Class TrimSplitByChar

Object

com.owenfeehan.pathpatternfinder.trim.TrimSplitByChar

All Implemented Interfaces:

TrimOperation<String>

public class TrimSplitByChar
extends Object
implements TrimOperation<String>

Attempts to split a string by finding a common special character in all strings.

It then creates two new unresolved elements to the left, and right of the character, as well as a constant element representing the character itself.

Note that we do not perform any case-sensitive matching on the assumption that the characters used in splitChar will typically be special characters for which case is irrelevant.
