Interface UriInfo

public interface UriInfo

An injectable interface that provides access to application and request URI information. Relative URIs are relative to the base URI of the application, see getBaseUri().

All methods throw java.lang.IllegalStateException if called outside the scope of a request (e.g. from a provider constructor).

Method Detail

getPath

java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

getPath

java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

getPathSegments

java.util.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:

java.lang.IllegalStateException - if called outside the scope of a request

See Also:

PathSegment, Matrix URIs

getPathSegments

java.util.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:

java.lang.IllegalStateException - if called outside the scope of a request

See Also:

PathSegment, Matrix URIs

getRequestUri

java.net.URI getRequestUri()

Get the absolute request URI including any query parameters.

Returns:

the absolute request URI

Throws:

java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

getAbsolutePath

java.net.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.getBase().resolve(uriInfo.getPath()).

Returns:

the absolute path of the request

Throws:

java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

getBaseUri

java.net.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<java.lang.String,java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

See Also:

Path, PathParam

getPathParameters

MultivaluedMap<java.lang.String,java.lang.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:

java.lang.IllegalStateException - if called outside the scope of a request

See Also:

Path, PathParam

getQueryParameters

MultivaluedMap<java.lang.String,java.lang.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 values are decoded, equivalent to getQueryParameters(true).

Returns:

an unmodifiable map of query parameter names and values

Throws:

java.lang.IllegalStateException - if called outside the scope of a request

getQueryParameters

MultivaluedMap<java.lang.String,java.lang.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 values are decoded (true) or not (false).

Returns:

an unmodifiable map of query parameter names and values

Throws:

java.lang.IllegalStateException - if called outside the scope of a request

getMatchedURIs

java.util.List<java.lang.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

Returns:

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

getMatchedURIs

java.util.List<java.lang.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.

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

java.util.List<java.lang.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

Returns:

a read-only list of matched resource class instances.
