Method Detail

keyMatch

public static boolean keyMatch(java.lang.String key1,
                               java.lang.String key2)

keyMatch determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.

 For example, "/foo/bar" matches "/foo/*"
 

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

keyMatch2

public static boolean keyMatch2(java.lang.String key1,
                                java.lang.String key2)

keyMatch2 determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.

 For example, "/foo/bar" matches "/foo/*", "/resource1" matches "/:resource"
 

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

keyMatch3

public static boolean keyMatch3(java.lang.String key1,
                                java.lang.String key2)

keyMatch3 determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *.

 For example, "/foo/bar" matches "/foo/*", "/resource1" matches "/{resource}"
 

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

keyMatch4

public static boolean keyMatch4(java.lang.String key1,
                                java.lang.String key2)

KeyMatch4 determines whether key1 matches the pattern of key2 (similar to RESTful path), key2 can contain a *. Besides what KeyMatch3 does, KeyMatch4 can also match repeated patterns:

 "/parent/123/child/123" matches "/parent/{id}/child/{id}"
 "/parent/123/child/456" does not match "/parent/{id}/child/{id}"
 But KeyMatch3 will match both.
 

Attention: key1 cannot contain English commas.

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

keyGetFunc

public static java.lang.String keyGetFunc(java.lang.String key1,
                                          java.lang.String key2)

KeyGet returns the matched part. For example, "/foo/bar/foo" matches "/foo/*", "bar/foo" will been returned

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

the matched part.

keyGet2Func

public static java.lang.String keyGet2Func(java.lang.String key1,
                                           java.lang.String key2,
                                           java.lang.String pathVar)

KeyGet2 returns value matched pattern.For example, "/resource1" matches "/:resource", if the pathVar == "resource", then "resource1" will be returned.

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

the matched part.

regexMatch

public static boolean regexMatch(java.lang.String key1,
                                 java.lang.String key2)

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

ipMatch

public static boolean ipMatch(java.lang.String ip1,
                              java.lang.String ip2)

ipMatch determines whether IP address ip1 matches the pattern of IP address ip2, ip2 can be an IP address or a CIDR pattern. For example, "192.168.2.123" matches "192.168.2.0/24"

Parameters:

ip1 - the first argument.

ip2 - the second argument.

Returns:

whether ip1 matches ip2.

globMatch

whether key1 matches key2.

allMatch

public static boolean allMatch(java.lang.String key1,
                               java.lang.String key2)

allMatch determines whether key1 matches the pattern of key2 , key2 can contain a *.

 For example, "*" matches everything
 

Parameters:

key1 - the first argument.

key2 - the second argument.

Returns:

whether key1 matches key2.

generateGFunction

public static com.googlecode.aviator.runtime.type.AviatorFunction generateGFunction(java.lang.String name,
                                                                                    RoleManager rm)
