compareTo

public int compareTo(Object object)

Specified by:

compareTo in interface Comparable

implies

public boolean implies(URLPattern urlPattern)

Does this pattern imply (that is, match) the argument pattern? This method follows the same rules (in the same order) as those used for mapping requests to servlets.

Two URL patterns match if they are related as follows:

• their pattern values are String equivalent, or
• this pattern is the path-prefix pattern "/*", or
• this pattern is a path-prefix pattern (that is, it starts with "/" and ends with "/*") and the argument pattern starts with the substring of this pattern, minus its last 2 characters, and the next character of the argument pattern, if there is one, is "/", or
• this pattern is an extension pattern (that is, it starts with "*.") and the argument pattern ends with this pattern, or
• the reference pattern is the special default pattern, "/", which matches all argument patterns.

Parameters:

urlPattern - URLPattern whose path will be compared to this URLPattern

Returns:

Whether the given URLPattern matches the present URLPattern.

getPatternDepth

public int getPatternDepth()

match

public static boolean match(String originalPattern,
                            String newPattern)

Minor utility method which instantiates a pattern before comparing it against another.

Parameters:

originalPattern - The pattern to compare against

newPattern - The pattern to compare

Returns:

equals

public boolean equals(Object object)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object
