Constructor Summary
`ExprSeparatorWithStrings()` The constructor.

Method Summary
`boolean`	`endChar(char c)` Called to check if more characters are expected in the free part of the token. Overridden to find the end of the token.
`boolean`	`hasFreePart()` Called to check if more characters are expected to follow after addChar has returned true. If true, then any following characters will be fed to endChar until endChar returns true. The default behaviour is to return false. Overridden to return true.
`void`	`reset()` Called to reset the separator before staring to look for a new token.
`int`	`tokenLength()` Returns the length of the matched token. It is not required to be meaningful unless addChar has returned true and hasFreePart returned false or endChar returned true. Overridden to return the entire length of the token.
