ContainerRequestContext (Red Hat JBoss Enterprise Application Platform 7.0.0.GA public API)

All Known Implementing Classes:

PostMatchContainerRequestContext, PreMatchContainerRequestContext, ResponseContainerRequestContext
```
public interface ContainerRequestContext
```
Container request filter context. A mutable class that provides request-specific information for the filter, such as request URI, message headers, message entity or request-scoped properties. The exposed setters allow modification of the exposed request-specific information.

- 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.

    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.
