Note that this is a very different mapping to that provided by PathMap in Jetty2.

This class is not synchronized for get's. If concurrent modifications are possible then it should be synchronized at a higher level.

PathMap

public PathMap()

Construct empty PathMap.

PathMap

public PathMap(int capacity)

Construct empty PathMap.

PathMap

public PathMap(java.util.Map m)

Construct from dictionary PathMap.

setPathSpecSeparators

public static void setPathSpecSeparators(java.lang.String s)

Set the path spec separator. Multiple path specification may be included in a single string if they are separated by the characters set in this string. The default value is ":," or whatever has been set by the system property org.mortbay.http.PathMap.separators

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Description copied from interface: java.io.Externalizable

This method is responsible for writing the instance data of an object to the passed in stream. Note that this stream is not a subclass of OutputStream, but rather is a class that implements the ObjectOutput interface. That interface provides a number of methods for writing Java data values to a stream.

Not that the implementation of this method must be coordinated with the implementation of readExternal.

Specified by:

writeExternal in interface java.io.Externalizable

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Description copied from interface: java.io.Externalizable

This method restores an object's state by reading in the instance data for the object from the passed in stream. Note that this stream is not a subclass of InputStream, but rather is a class that implements the ObjectInput interface. That interface provides a mechanism for reading in Java data types from a stream.

Note that this method must be compatible with writeExternal. It must read back the exact same types that were written by that method in the exact order they were written.

If this method needs to read back an object instance, then the class for that object must be found and loaded. If that operation fails, then this method throws a ClassNotFoundException

Specified by:

readExternal in interface java.io.Externalizable

put

public java.lang.Object put(java.lang.Object pathSpec,
                            java.lang.Object object)

Add a single path match to the PathMap.

Specified by:

put in interface java.util.Map

match

public java.lang.Object match(java.lang.String path)

Get object matched by the path.

getMatch

public java.util.Map.Entry getMatch(java.lang.String path)

Get the entry mapped by the best specification.

getMatches

public java.util.List getMatches(java.lang.String path)

Get all entries matched by the path. Best match first.

remove

public java.lang.Object remove(java.lang.Object pathSpec)

Description copied from class: java.util.HashMap

Removes from the HashMap and returns the value which is mapped by the supplied key. If the key maps to nothing, then the HashMap remains unchanged, and null is returned. NOTE: Since the value could also be null, you must use containsKey to see if you are actually removing a mapping.

Specified by:

remove in interface java.util.Map

clear

public void clear()

Description copied from class: java.util.HashMap

Clears the Map so it has no keys. This is O(1).

Specified by:

clear in interface java.util.Map

match

public static boolean match(java.lang.String pathSpec,
                            java.lang.String path)
                     throws java.lang.IllegalArgumentException

pathMatch

public static java.lang.String pathMatch(java.lang.String pathSpec,
                                         java.lang.String path)

Return the portion of a path that matches a path spec.

pathInfo

public static java.lang.String pathInfo(java.lang.String pathSpec,
                                        java.lang.String path)

Return the portion of a path that is after a path spec.

relativePath

public static java.lang.String relativePath(java.lang.String base,
                                            java.lang.String pathSpec,
                                            java.lang.String path)

Relative path.
