Interface ClientRequestContext


  • public interface ClientRequestContext
    Client 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.

      • getProperty

        java.lang.Object getProperty​(java.lang.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.

        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

        java.util.Collection<java.lang.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.

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

        void setProperty​(java.lang.String name,
                         java.lang.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.

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

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

        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.
