Méthode Description
getHashForParts ( $pattern ) : string returns a hash for one pattern
getHashForPattern ( string $pattern, boolean $variants = false ) : string | array Gets a hash or an array of hashes from the first characters of a pattern/user agent, that can be used for a fast comparison, by comparing only the hashes, without having to match the complete pattern against the user agent.
getPatternLength ( string $pattern ) : integer Gets the minimum length of the patern (used in the getPatterns() method to check against the user agent length)

Method Details

getHashForPattern() public static méthode

With the variants options, all variants from the maximum number of pattern characters to one character will be returned. This is required in some cases, the a placeholder is used very early in the pattern. Example: Pattern: "Mozilla/* (Nintendo 3DS; *) Version/*" User agent: "Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7567.US" In this case the has for the pattern is created for "Mozilla/" while the pattern for the hash for user agent is created for "Mozilla/5.0". The variants option results in an array with hashes for "Mozilla/5.0", "Mozilla/5.", "Mozilla/5", "Mozilla/" ... "M", so that the pattern hash is included.
