com.android.tools.lint.checks.AndroidPatternMatcher

public class AndroidPatternMatcher
extends java.lang.Object

A simple pattern matcher, which is safe to use on untrusted data: it does not provide full reg-exp support, only simple globbing that can not be used maliciously.

Constant Field Values

PATTERN_SIMPLE_GLOB

public static final int PATTERN_SIMPLE_GLOB

Pattern type: the given pattern is interpreted with a simple glob syntax for matching against the string it is tested against. In this syntax, you can use the '*' character to match against zero or more occurrences of the character immediately before. If the character before it is '.' it will match any character. The character '\' can be used as an escape. This essentially provides only the '*' wildcard part of a normal regexp.

Constant Field Values

PATTERN_ADVANCED_GLOB

public static final int PATTERN_ADVANCED_GLOB

Pattern type: the given pattern is interpreted with a regular expression-like syntax for matching against the string it is tested against. Supported tokens include dot (.) and sets ([...]) with full support for character ranges and the not (^) modifier. Supported modifiers include star (*) for zero-or-more, plus (+) for one-or-more and full range ({...}) support. This is a simple evaluation implementation in which matching is done against the pattern in real time with no backtracking support.
