Method Detail

getPath

String getPath()
Get the path of the current request relative to the base URI as a string. All sequences of escaped octets are decoded, equivalent to getPath(true).

Returns:
the relative URI path.
Throws:
IllegalStateException - if called outside the scope of a request.

getPath

String getPath(boolean decode)
Get the path of the current request relative to the base URI as a string.

Parameters:
decode - controls whether sequences of escaped octets are decoded (true) or not (false).
Returns:
the relative URI path
Throws:
IllegalStateException - if called outside the scope of a request.

getPathSegments

List<PathSegment> getPathSegments()
Get the path of the current request relative to the base URI as a list of PathSegment. This method is useful when the path needs to be parsed, particularly when matrix parameters may be present in the path. All sequences of escaped octets in path segments and matrix parameter values are decoded, equivalent to getPathSegments(true).

Returns:
an unmodifiable list of PathSegment. The matrix parameter map of each path segment is also unmodifiable.
Throws:
IllegalStateException - if called outside the scope of a request
See Also:
PathSegment, Matrix URIs

getPathSegments

List<PathSegment> getPathSegments(boolean decode)
Get the path of the current request relative to the base URI as a list of PathSegment. This method is useful when the path needs to be parsed, particularly when matrix parameters may be present in the path.

Parameters:
decode - controls whether sequences of escaped octets in path segments and matrix parameter values are decoded (true) or not (false).
Returns:
an unmodifiable list of PathSegment. The matrix parameter map of each path segment is also unmodifiable.
Throws:
IllegalStateException - if called outside the scope of a request
See Also:
PathSegment, Matrix URIs

getRequestUri

URI getRequestUri()
Get the absolute request URI including any query parameters.

Returns:
the absolute request URI
Throws:
IllegalStateException - if called outside the scope of a request

getRequestUriBuilder

UriBuilder getRequestUriBuilder()
Get the absolute request URI in the form of a UriBuilder.

Returns:
a UriBuilder initialized with the absolute request URI.
Throws:
IllegalStateException - if called outside the scope of a request.

getAbsolutePath

URI getAbsolutePath()
Get the absolute path of the request. This includes everything preceding the path (host, port etc) but excludes query parameters. This is a shortcut for uriInfo.getBaseUri().resolve(uriInfo.getPath(false)).

Returns:
the absolute path of the request.
Throws:
IllegalStateException - if called outside the scope of a request.

getAbsolutePathBuilder

UriBuilder getAbsolutePathBuilder()
Get the absolute path of the request in the form of a UriBuilder. This includes everything preceding the path (host, port etc) but excludes query parameters.

Returns:
a UriBuilder initialized with the absolute path of the request.
Throws:
IllegalStateException - if called outside the scope of a request.

getBaseUri

URI getBaseUri()
Get the base URI of the application. URIs of root resource classes are all relative to this base URI.

Returns:
the base URI of the application.

getBaseUriBuilder

UriBuilder getBaseUriBuilder()
Get the base URI of the application in the form of a UriBuilder.

Returns:
a UriBuilder initialized with the base URI of the application.

getPathParameters

MultivaluedMap<String,String> getPathParameters()
Get the values of any embedded URI template parameters. All sequences of escaped octets are decoded, equivalent to getPathParameters(true).

Returns:
an unmodifiable map of parameter names and values.
Throws:
IllegalStateException - if called outside the scope of a request.
See Also:
Path, PathParam

getPathParameters

MultivaluedMap<String,String> getPathParameters(boolean decode)
Get the values of any embedded URI template parameters.

Parameters:
decode - controls whether sequences of escaped octets are decoded (true) or not (false).
Returns:
an unmodifiable map of parameter names and values
Throws:
IllegalStateException - if called outside the scope of a request.
See Also:
Path, PathParam

getQueryParameters

MultivaluedMap<String,String> getQueryParameters()
Get the URI query parameters of the current request. The map keys are the names of the query parameters with any escaped characters decoded. All sequences of escaped octets in parameter names and values are decoded, equivalent to getQueryParameters(true).

Returns:
an unmodifiable map of query parameter names and values.
Throws:
IllegalStateException - if called outside the scope of a request.

getQueryParameters

MultivaluedMap<String,String> getQueryParameters(boolean decode)
Get the URI query parameters of the current request. The map keys are the names of the query parameters with any escaped characters decoded.

Parameters:
decode - controls whether sequences of escaped octets in parameter names and values are decoded (true) or not (false).
Returns:
an unmodifiable map of query parameter names and values.
Throws:
IllegalStateException - if called outside the scope of a request.

getMatchedURIs

List<String> getMatchedURIs()
Get a read-only list of URIs for matched resources. Each entry is a relative URI that matched a resource class, a sub-resource method or a sub-resource locator. All sequences of escaped octets are decoded, equivalent to getMatchedURIs(true). Entries do not include query parameters but do include matrix parameters if present in the request URI. Entries are ordered in reverse request URI matching order, with the current resource URI first. E.g. given the following resource classes:
@Path("foo")
 public class FooResource {
  @GET
  public String getFoo() {...}

  @Path("bar")
  public BarResource getBarResource() {...}
 }

 public class BarResource {
  @GET
  public String getBar() {...}
 }
 

The values returned by this method based on request uri and where the method is called from are:

Request Called from Value(s)
GET /foo FooResource.getFoo foo
GET /foo/bar FooResource.getBarResource foo/bar, foo
GET /foo/bar BarResource.getBar foo/bar, foo
In case the method is invoked prior to the request matching (e.g. from a pre-matching filter), the method returns an empty list.

Returns:
a read-only list of URI paths for matched resources.

getMatchedURIs

List<String> getMatchedURIs(boolean decode)
Get a read-only list of URIs for matched resources. Each entry is a relative URI that matched a resource class, a sub-resource method or a sub-resource locator. Entries do not include query parameters but do include matrix parameters if present in the request URI. Entries are ordered in reverse request URI matching order, with the current resource URI first. See getMatchedURIs() for an example. In case the method is invoked prior to the request matching (e.g. from a pre-matching filter), the method returns an empty list.

Parameters:
decode - controls whether sequences of escaped octets are decoded (true) or not (false).
Returns:
a read-only list of URI paths for matched resources.

getMatchedResources

List<Object> getMatchedResources()
Get a read-only list of the currently matched resource class instances. Each entry is a resource class instance that matched the request URI either directly or via a sub-resource method or a sub-resource locator. Entries are ordered according to reverse request URI matching order, with the current resource first. E.g. given the following resource classes:
@Path("foo")
 public class FooResource {
  @GET
  public String getFoo() {...}

  @Path("bar")
  public BarResource getBarResource() {...}
 }

 public class BarResource {
  @GET
  public String getBar() {...}
 }
 

The values returned by this method based on request uri and where the method is called from are:

Request Called from Value(s)
GET /foo FooResource.getFoo FooResource
GET /foo/bar FooResource.getBarResource FooResource
GET /foo/bar BarResource.getBar BarResource, FooResource
In case the method is invoked prior to the request matching (e.g. from a pre-matching filter), the method returns an empty list.

Returns:
a read-only list of matched resource class instances.

resolve

URI resolve(URI uri)
Resolve a relative URI with respect to the base URI of the application. The resolved URI returned by this method is normalized. If the supplied URI is already resolved, it is just returned.

Parameters:
uri - URI to resolve against the base URI of the application.
Returns:
newly resolved URI or supplied URI if already resolved.
Since:
2.0

relativize

URI relativize(URI uri)

Relativize a URI with respect to the current request URI. Relativization works as follows:

  1. If the URI to relativize is already relative, it is first resolved using resolve(java.net.URI).
  2. The resulting URI is relativized with respect to the current request URI. If the two URIs do not share a prefix, the URI computed in step 1 is returned.

Examples (for base URI http://host:port/app/root/):

Request URI: http://host:port/app/root/a/b/c
Supplied URI: a/b/c/d/e
Returned URI: d/e

Request URI: http://host1:port1/app/root/a/b/c
Supplied URI: http://host2:port2/app2/root2/a/d/e
Returned URI: http://host2:port2/app2/root2/a/d/e

In the second example, the supplied URI is returned given that it is absolute and there is no common prefix between it and the request URI.

Parameters:
uri - URI to relativize against the request URI.
Returns:
newly relativized URI.
Throws:
IllegalStateException - if called outside the scope of a request.
Since:
2.0
