Interface PathMatcher

All Superinterfaces:

Matcher<String>

All Known Implementing Classes:

PathMatcherImpl

public interface PathMatcher
extends Matcher<String>

Path Matcher, matching its ANT like path pattern against the path provided to the isMatching(String) and the like methods. The PathMatcher applies the following rules from the ANT path pattern to the path provided via isMatching(String) method: A single asterisk ("*") matches zero or more characters within a path name. A double asterisk ("**") matches zero or more characters across directory levels. A question mark ("?") matches exactly one character within a path name. The single asterisk ("*"), the double asterisk ("**") and the question mark ("?") we refer to as wildcards: You get an array with the substitutes of the wildcards using the method toWildcardSubstitutes(String) (or null, if your String does not match your path pattern). You may name a wildcard by prefixing it with "${someWildcardName}=". For example a named wildcard may look as follows: "${arg1}=*" or "${arg2}=**" or "${arg3}=?". A placeholder "${arg1}" with no wildcard assignment "=" is equivalent to "${arg1}=*". The regular expression pattern construction is inspired by: "http://stackoverflow.com/questions/33171025/regex-matching-an-ant-path"

Method Detail

isMatching

boolean isMatching(String aPath)

The this method applies the following rules from the configured ANT path pattern to the path provided via isMatching(String) method: A single asterisk ("*") matches zero or more characters within a path name. A double asterisk ("**") matches zero or more characters across directory levels. A question mark ("?") matches exactly one character within a path name Tests whether the given event is matching the mathcer's criteria.

Specified by:

isMatching in interface Matcher<String>

Parameters:

aPath - The matchee used for testing matchability.

Returns:

True in case the matchee matches the matcher's criteria, else false.

getPathPattern

String getPathPattern()

Returns the path pattern being used by the PathMatcher.

Returns:

The path pattern being used.

toWildcardSubstitutes

WildcardSubstitutes toWildcardSubstitutes(String aPath)

Returns all available wildcard substitutes as well as the named wildcard substitutes.

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

Returns:

The WildcardSubstitutes of the wildcards being substituted.

toWildcardReplacements

String[] toWildcardReplacements(String aPath)

Returns an array of the wildcard substitutes for the wildcards in your path pattern (see getPathPattern()) compared to the actual path (as of toWildcardSubstitutes(String)). The order of the wildcard substitutes aligns to the order of the wildcards (from left to right) defined in your path pattern.

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

Returns:

The text substituting the wildcards in the order of the wildcards being substituted or null if there are none such substitutes.

toWildcardReplacementAt

String toWildcardReplacementAt(String aPath,
                               int aIndex)

Returns the wildcard substitute for the wildcards in your path pattern (see getPathPattern()) compared to the actual path (as of toWildcardSubstitutes(String)). The text of the wildcard substitute aligns to the index of the wildcard (from left to right) as defined in your path pattern.

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

aIndex - The index of the wildcard in question for which to retrieve the substitute.

Returns:

The text substituting the wildcard at the given path pattern's wildcard index or null if there is none such substitute.

toWildcardReplacementsAt

String[] toWildcardReplacementsAt(String aPath,
                                  int... aIndexes)

Returns the wildcard substitutes for the wildcards in your path pattern (see getPathPattern()) compared to the actual path (as of toWildcardSubstitutes(String)). The text of the wildcard substitutes aligns to the indexes of the wildcard (from left to right) as defined in your path pattern.

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

aIndexes - The indexes of the wildcards in question for which to retrieve the substitutes.

Returns:

The text substituting the wildcards at the given path pattern's wildcard indexes or null if there is none such substitute.

toWildcardReplacement

String toWildcardReplacement(String aPath,
                             String aWildcardName)

Returns the wildcard substitute for the wildcards in your path pattern (see getPathPattern()) compared to the actual path (as of toWildcardSubstitutes(String)). The text of the wildcard substitute aligns to the name of the wildcard (as defined in your path pattern).

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

aWildcardName - The name of the wildcard in question for which to retrieve the substitute.

Returns:

The text substituting the wildcard with the given path pattern's wildcard name or null if there is none such substitute.

toWildcardReplacements

String[] toWildcardReplacements(String aPath,
                                String... aWildcardNames)

Returns the wildcard substitutes for the wildcards in your path pattern (see getPathPattern()) compared to the actual path (as of toWildcardSubstitutes(String)). The text of the wildcard substitutes aligns to the order of the provided wildcard names (as defined in your path pattern).

Parameters:

aPath - The path for which to retrieve the wildcard substitutes.

aWildcardNames - The names of the wildcards in question for which to retrieve the substitutes in the order of the provided names.

Returns:

The text substituting the wildcard with the given path pattern's wildcard names or null if there are none such substitute.

getWildcardNames

String[] getWildcardNames()

Retrieves the list of wildcard names identifying the wildcards as specified by the path pattern.

Returns:

The wild card names or null of no wild card names have been defined.
