Introduction
Console uses the Java Regular Expression system for defining Regular Expressions items used in the following features:
- Transaction configuration rules
- Excluded table names for transaction built-in data entities
- Architecture models and Quality Rules
You can find out more about this here: https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html.
Example patterns
Some example patterns are shown below:
| String searched | Regular expression to enter |
|---|---|
| Strings containing "src" | src |
| Strings exactly matching "src" | ^src$ |
| Strings starting with "src" | ^src |
| Strings ending with "src" | src$ |
| A string exactly matching "src" | /src$ |
| A string exactly matching ".src" | /\.src$ |
| One or more upper case letters, but not zero | [A-Z]+ |
| Any sequence of characters or any length - i.e. match all tables | .* |
Limitations
| Number of characters | You can enter a Regular Expression of up to 500 characters. |
|---|---|
| String matching | By default Console matches only part of the string corresponding to the Regular Expression you have entered, rather than the entire string. As such to match an entire string please use the ^ and $ characters around the required string. |
| Reserved characters | The following characters are "reserved characters" and therefore must be "escaped" with a backslash before being used in a Regular Expression: . ( ) [ ] ^ $ So, for example to match for an item (a folder in this case) entitled ComplexityVolume(PercentageofLOC), you will need to enter ^ComplexityVolume\(PercentageofLOC\) in the Regular expression field. Please see the section entitled "Backslashes, escapes, and quoting" in https://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html for more information. |
