End Of File Matcher
The end of file matcher is a zero-width assertion that tests if the matcher engine is currently at the end of the file being matched. If the engine is at the end of file, this matcher will return true. It is possible to negate the logic of this matcher via the "negate" attribute.

negate | Determines if the matcher should or should not match letters. True will match letters and false will match anything except letters. | boolean | true | no |
End Of Line Matcher
The end of line matcher is a zero-width assertion that tests if the matcher engine is currently at a '\r' character, a '\n' character, or the end of the file. If any of those conditions are true, the matcher will return true. It is possible to negate the logic of this matcher via the "negate" attribute.

Lookahead Matcher
The lookahead matcher allows for the test of a pattern without consuming the matched text. The match can be negated to return true only if the pattern does not match. This is useful when matching keywords where you can test that no other letter follows the matched keyword without consuming the character being tested.
If this element contains more than one child, all children will be wrapped in an AndMatcher which then becomes the child of this element.

Start Of File Matcher
The start of file matcher is a zero-width assertion that tests if the matcher engine is currently at the start of the file being matched. If the engine is at the start of the file, this matcher will return true. It is possible to negate the logic of this matcher via the "negate" attribute.

If any of those conditions are true, the matcher will return true. It is possible to negate the logic of this matcher via the "negate" attribute.

Word Boundary Matcher
The word boundary matcher determines if the current offset within a string is at a word boundary. A word boundary is defined as the position between two characters where one is a word character as defined but the WordMatcher and the other is not a word character. Special cases occur at the before the first character and after the last character. In those cases, this matcher will return true. It is possible to negate the logic of this matcher via the "negate" attribute.
