Class DefaultRequestMatcherRegistry.Path<H>

java.lang.Object

org.mule.service.http.impl.service.util.DefaultRequestMatcherRegistry.Path<H>

Enclosing class:

DefaultRequestMatcherRegistry<T>

public static class DefaultRequestMatcherRegistry.Path<H>
extends Object

Represents a URI path, which can be a parent to regular sub paths, a catch all sub path (/*) and a URI param path (/{param}). Request handler and matcher pairs (handlers for different methods, for example) can be added and removed from it. If all its handlers and children's handlers' are removed, it will notify its parent the path itself can be removed. This means that the tree-like structure that results from binding paths together changes as handlers are created and disposed so special care needs to be taken regarding available paths.

Constructor Detail

Path

public Path(String name,
            DefaultRequestMatcherRegistry.Path parent)

Creates a new instance for the given name and with the provided parent.

Parameters:

name - for this path

parent - of this path

Method Detail

getCatchAll

public DefaultRequestMatcherRegistry.Path getCatchAll()

Returns:

the catch all path for this one (/*)

getCatchAllUriParam

public DefaultRequestMatcherRegistry.Path getCatchAllUriParam()

Returns:

the catch all uri param path for this one (/{param})

getChildPath

public DefaultRequestMatcherRegistry.Path getChildPath(String subPath,
                                                       String nextSubPath)

Parameters:

subPath - the sub part of the path to find

nextSubPath - the next sub part of the path. It is useful for deciding between static paths and middle-wildcard paths when they are similar.

Returns:

the node with the existent mappings. null if there's no such node.

getLastChildPath

public DefaultRequestMatcherRegistry.Path getLastChildPath(String subPath)

Parameters:

subPath - a sub part of the path

Returns:

the node with the existent mappings. null if there's no such node.

addRequestHandlerMatcherPair

public void addRequestHandlerMatcherPair(DefaultRequestMatcherRegistry.RequestHandlerMatcherPair requestHandlerMatcherPair)

Adds a new request handler and matcher for this path.

Parameters:

requestHandlerMatcherPair - the pair to add

addChildPath

public void addChildPath(String pathName,
                         DefaultRequestMatcherRegistry.Path path)

Adds a new sub or uri param path.

Parameters:

pathName - the path name

path - the representation of this path

removeChildPath

public void removeChildPath(String pathName)

Removes a sub path and checks whether this path itself should be removed.

Parameters:

pathName - the path name

isEmpty

public boolean isEmpty()

Returns:

whether this path is empty, meaning it has no handlers or sub paths of any kind which are in turn non empty.

getSubPaths

public Map<String,DefaultRequestMatcherRegistry.Path> getSubPaths()

Returns:

the map of sub paths available

getRequestHandlerMatcherPairs

public List<DefaultRequestMatcherRegistry.RequestHandlerMatcherPair<H>> getRequestHandlerMatcherPairs()

Returns:

the list of handlers for this path

addWildcardRequestHandler

public void addWildcardRequestHandler(DefaultRequestMatcherRegistry.RequestHandlerMatcherPair requestHandlerMatcherPair)

Adds a request handler matcher pair for the catch all sub path (/*).

Parameters:

requestHandlerMatcherPair - the pair to add

removeRequestHandlerMatcherPair

public boolean removeRequestHandlerMatcherPair(DefaultRequestMatcherRegistry.RequestHandlerMatcherPair requestHandlerMatcherPair)

Removes a request handler and matcher pair whether it's in a regular sub path, the catch all sub path or a uri param sub path. The latter two will be removed if empty as will the path it self if now empty.

Parameters:

requestHandlerMatcherPair -

Returns:

whether the removal was successful
