Java examples for Regular Expressions:Pattern
When using the following method to create Pattern instance
Pattern pattern = Pattern.compile ("[A-Z][a-zA-Z]*", Pattern.CASE_INSENSITIVE | Pattern.UNIX_LINES);
We can have the following options.
| Flag name | Embedded expression | Description |
|---|---|---|
| UNIX_LINES | (?d) | Enables Unix lines mode. |
| CASE_INSENSITIVE | (?i) | Enables case-insensitive pattern matching and may incur a small performance penalty. |
| UNICODE_CASE | (?iu) | Unicode-aware, case-folding mode. |
| COMMENTS | (?x) | Permits whitespace and comments in the pattern. |
| MULTILINE | (?m) | Turns on multiline mode. |
| DOTALL | (?s) | Dot (.) character matches any character, even line separators. |
| CANON_EQ | None | Enables canonical equivalence. |
