Method Detail

getProperty

Object getProperty(String name)
Returns the property with the given name registered in the current request/response exchange context, or null if there is no property by that name.

A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

A list of supported properties can be retrieved using getPropertyNames(). Custom property names should follow the same convention as package names.

In a Servlet container, the properties are synchronized with the ServletRequest and expose all the attributes available in the ServletRequest. Any modifications of the properties are also reflected in the set of properties of the associated ServletRequest.

Parameters:
name - a String specifying the name of the property.
Returns:
an Object containing the value of the property, or null if no property exists matching the given name.
See Also:
getPropertyNames()

getPropertyNames

Collection<String> getPropertyNames()
Returns an immutable collection containing the property names available within the context of the current request/response exchange context.

Use the getProperty(java.lang.String) method with a property name to get the value of a property.

In a Servlet container, the properties are synchronized with the ServletRequest and expose all the attributes available in the ServletRequest. Any modifications of the properties are also reflected in the set of properties of the associated ServletRequest.

Returns:
an immutable collection of property names.
See Also:
getProperty(java.lang.String)

setProperty

void setProperty(String name,
                 Object object)
Binds an object to a given property name in the current request/response exchange context. If the name specified is already used for a property, this method will replace the value of the property with the new value.

A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

A list of supported properties can be retrieved using getPropertyNames(). Custom property names should follow the same convention as package names.

If a null value is passed, the effect is the same as calling the removeProperty(String) method.

In a Servlet container, the properties are synchronized with the ServletRequest and expose all the attributes available in the ServletRequest. Any modifications of the properties are also reflected in the set of properties of the associated ServletRequest.

Parameters:
name - a String specifying the name of the property.
object - an Object representing the property to be bound.

removeProperty

void removeProperty(String name)
Removes a property with the given name from the current request/response exchange context. After removal, subsequent calls to getProperty(java.lang.String) to retrieve the property value will return null.

In a Servlet container, the properties are synchronized with the ServletRequest and expose all the attributes available in the ServletRequest. Any modifications of the properties are also reflected in the set of properties of the associated ServletRequest.

Parameters:
name - a String specifying the name of the property to be removed.

getUriInfo

UriInfo getUriInfo()
Get request URI information. The returned object contains "live" view of the request URI information in a sense that any changes made to the request URI using one of the setRequestUri(...) methods will be reflected in the previously returned UriInfo instance.

Returns:
request URI information.

setRequestUri

void setRequestUri(URI requestUri)
Set a new request URI using the current base URI of the application to resolve the application-specific request URI part.

Note that the method is usable only in pre-matching filters, prior to the resource matching occurs. Trying to invoke the method in a filter bound to a resource method results in an IllegalStateException being thrown.

Parameters:
requestUri - new URI of the request.
Throws:
IllegalStateException - in case the method is not invoked from a pre-matching request filter.
See Also:
setRequestUri(java.net.URI, java.net.URI)

setRequestUri

void setRequestUri(URI baseUri,
                   URI requestUri)
Set a new request URI using a new base URI to resolve the application-specific request URI part.

Note that the method is usable only in pre-matching filters, prior to the resource matching occurs. Trying to invoke the method in a filter bound to a resource method results in an IllegalStateException being thrown.

Parameters:
baseUri - base URI that will be used to resolve the application-specific part of the request URI.
requestUri - new URI of the request.
Throws:
IllegalStateException - in case the method is not invoked from a pre-matching request filter.
See Also:
setRequestUri(java.net.URI)

getRequest

Request getRequest()
Get the injectable request information.

Returns:
injectable request information.

getMethod

String getMethod()
Get the request method.

Returns:
the request method.
See Also:
HttpMethod

setMethod

void setMethod(String method)
Set the request method.

Note that the method is usable only in pre-matching filters, prior to the resource matching occurs. Trying to invoke the method in a filter bound to a resource method results in an IllegalStateException being thrown.

Parameters:
method - new request method.
Throws:
IllegalStateException - in case the method is not invoked from a pre-matching request filter.
See Also:
HttpMethod

getHeaders

MultivaluedMap<String,String> getHeaders()
Get the mutable request headers multivalued map.

Returns:
mutable multivalued map of request headers.
See Also:
getHeaderString(String)

getHeaderString

String getHeaderString(String name)
Get a message header as a single string value.

Parameters:
name - the message header.
Returns:
the message header value. If the message header is not present then null is returned. If the message header is present but has no value then the empty string is returned. If the message header is present more than once then the values of joined together and separated by a ',' character.
See Also:
getHeaders()

getDate

Date getDate()
Get message date.

Returns:
the message date, otherwise null if not present.

getLanguage

Locale getLanguage()
Get the language of the entity.

Returns:
the language of the entity or null if not specified

getLength

int getLength()
Get Content-Length value.

Returns:
Content-Length as integer if present and valid number. In other cases returns -1.

getMediaType

Get the media type of the entity.

Returns:
the media type or null if not specified (e.g. there's no request entity).

getAcceptableMediaTypes

List<MediaType> getAcceptableMediaTypes()
Get a list of media types that are acceptable for the response.

Returns:
a read-only list of requested response media types sorted according to their q-value, with highest preference first.

getAcceptableLanguages

Returns:
a read-only list of acceptable languages sorted according to their q-value, with highest preference first.

getCookies

Map<String,Cookie> getCookies()
Get any cookies that accompanied the request.

Returns:
a read-only map of cookie name (String) to Cookie.

hasEntity

boolean hasEntity()
Check if there is a non-empty entity input stream available in the request message. The method returns true if the entity is present, returns false otherwise.

Returns:
true if there is an entity present in the message, false otherwise.

getEntityStream

InputStream getEntityStream()
Get the entity input stream. The JAX-RS runtime is responsible for closing the input stream.

Returns:
entity input stream.

setEntityStream

void setEntityStream(InputStream input)
Set a new entity input stream. The JAX-RS runtime is responsible for closing the intput stream.

Parameters:
input - new entity input stream.

getSecurityContext

SecurityContext getSecurityContext()
Get the injectable security context information for the current request. The SecurityContext.getUserPrincipal() must return null if the current request has not been authenticated.

Returns:
injectable request security context information.

setSecurityContext
