URLPattern

URLPattern(java.lang.String pattern)

Creates a URLPattern instance from the specified pattern String.

Parameters:

pattern - the pattern String.

Method Detail

matches

boolean matches(URLPattern url)

Checks if this pattern matches the specified URLPattern.

The matching rules from the WebResourcePermission#implies:

1. their pattern values are String equivalent, or
2. this pattern is the path-prefix pattern "/*", or
3. 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
4. this pattern is an extension pattern (that is, it starts with "*.") and the argument pattern ends with this pattern, or 5. the reference pattern is the special default pattern, "/", which matches all argument patterns.

Parameters:

url - the URLPattern instance to which this pattern is to be matched.

Returns:

true if this pattern matches the specified URLPattern; false otherwise.

matches

4. this pattern is an extension pattern (that is, it starts with "*.") and the argument pattern ends with this pattern, or 5. the reference pattern is the special default pattern, "/", which matches all argument patterns.

Parameters:

urlPattern - a String representing the pattern to which this pattern is to be matched.

Returns:

true if this pattern matches the specified URLPattern; false otherwise.

getPattern

java.lang.String getPattern()

Obtains the String representation of this pattern.

Returns:

this pattern's String representation.

isDefault

boolean isDefault()

Checks if this pattern is a default (i.e. '/') pattern.

Returns:

true if this is a default pattern; false otherwise.

isExact

boolean isExact()

Checks if this pattern is an exact pattern.

Returns:

true if this is an exact pattern; false otherwise.

isExtension

Returns:

true if this is an extension pattern; false otherwise.

isPrefix

boolean isPrefix()

Checks if this pattern is a prefix (i.e. '/*' or '/.../*') pattern.

Returns:

true if this is a prefix pattern; false otherwise.
