Method Detail

getEntity

public Object getEntity()

Description copied from interface: WriterInterceptorContext

Get object to be written as HTTP entity.

Specified by:

getEntity in interface WriterInterceptorContext

Returns:

object to be written as HTTP entity.

setEntity

public void setEntity(Object entity)

Description copied from interface: WriterInterceptorContext

Update object to be written as HTTP entity.

Specified by:

setEntity in interface WriterInterceptorContext

Parameters:

entity - new object to be written.

getType

public Class getType()

Description copied from interface: InterceptorContext

Get Java type supported by corresponding message body provider.

Specified by:

getType in interface InterceptorContext

Returns:

java type supported by provider

setType

public void setType(Class type)

Description copied from interface: InterceptorContext

Update Java type before calling message body provider.

Specified by:

setType in interface InterceptorContext

Parameters:

type - java type for provider

getGenericType

public Type getGenericType()

Description copied from interface: InterceptorContext

Get the type of the object to be produced or written.

Specified by:

getGenericType in interface InterceptorContext

Returns:

type of object produced or written

setGenericType

public void setGenericType(Type genericType)

Description copied from interface: InterceptorContext

Update type of the object to be produced or written.

Specified by:

setGenericType in interface InterceptorContext

Parameters:

genericType - new type for object

getAnnotations

public Annotation[] getAnnotations()

Description copied from interface: InterceptorContext

Get an array of the annotations formally declared on the artifact that initiated the intercepted entity provider invocation. E.g. if the message body is to be converted into a method parameter, this will be the annotations on that parameter returned by Method.getParameterAnnotations(); if the server-side response entity instance is to be converted into an output stream, this will be the annotations on the matched resource method returned by Method.getAnnotations(). This method may return an empty array in case the interceptor is not invoked in a context of any particular resource method (e.g. as part of the client API), but will never return null.

Specified by:

getAnnotations in interface InterceptorContext

Returns:

annotations declared on the artifact that initiated the intercepted entity provider invocation.

setAnnotations

public void setAnnotations(Annotation[] annotations)

Description copied from interface: InterceptorContext

Update annotations on the formal declaration of the artifact that initiated the intercepted entity provider invocation. Calling this method has no effect in the client API.

Specified by:

setAnnotations in interface InterceptorContext

Parameters:

annotations - updated annotations declarataion of the artifact that initiated the intercepted entity provider invocation. Must not be null.

getMediaType

public MediaType getMediaType()

Description copied from interface: InterceptorContext

Get media type of HTTP entity.

Specified by:

getMediaType in interface InterceptorContext

Returns:

media type of HTTP entity

setMediaType

public void setMediaType(MediaType mediaType)

Description copied from interface: InterceptorContext

Update media type of HTTP entity.

Specified by:

setMediaType in interface InterceptorContext

Parameters:

mediaType - new type for HTTP entity

getHeaders

public MultivaluedMap<String,Object> getHeaders()

Description copied from interface: WriterInterceptorContext

Get mutable map of HTTP headers.

Specified by:

getHeaders in interface WriterInterceptorContext

Returns:

map of HTTP headers.

getOutputStream

public OutputStream getOutputStream()

Description copied from interface: WriterInterceptorContext

Get the output stream for the object to be written. The JAX-RS runtime is responsible for closing the output stream.

Specified by:

getOutputStream in interface WriterInterceptorContext

Returns:

output stream for the object to be written.

setOutputStream

public void setOutputStream(OutputStream outputStream)

Description copied from interface: WriterInterceptorContext

Update the output stream for the object to be written. The JAX-RS runtime is responsible for closing the output stream.

Specified by:

setOutputStream in interface WriterInterceptorContext

Parameters:

outputStream - new output stream for the object to be written.

proceed

public void proceed()
             throws IOException,
                    WebApplicationException

Description copied from interface: WriterInterceptorContext

Proceed to the next interceptor in the chain. Interceptors MUST explicitly call this method to continue the execution chain; the call to this method in the last interceptor of the chain will invoke the wrapped MessageBodyWriter.writeTo(T, java.lang.Class<?>, java.lang.reflect.Type, java.lang.annotation.Annotation[], javax.ws.rs.core.MediaType, javax.ws.rs.core.MultivaluedMap<java.lang.String, java.lang.Object>, java.io.OutputStream) method.

Specified by:

proceed in interface WriterInterceptorContext

Throws:

IOException - if an IO error arises or is thrown by the wrapped MessageBodyWriter.writeTo method.

WebApplicationException - thrown by the wrapped MessageBodyWriter.writeTo method.

writeTo

protected void writeTo(MessageBodyWriter writer)
                throws IOException

Throws:

IOException

getWriter

protected MessageBodyWriter getWriter()

resolveWriter

protected abstract MessageBodyWriter resolveWriter()
