Interface WriterInterceptorContext

All Superinterfaces:

InterceptorContext

public interface WriterInterceptorContext
extends InterceptorContext

Context class used by WriterInterceptor to intercept calls to MessageBodyWriter.writeTo(T, Class, Type, Annotation[], MediaType, MultivaluedMap, OutputStream). The getters and setters in this context class correspond to the parameters of the intercepted method.

Since:

2.0

Method Details

proceed

void proceed()
      throws IOException,
WebApplicationException

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, Class, Type, Annotation[], MediaType, MultivaluedMap, OutputStream) method.

Throws:

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

WebApplicationException - thrown by the wrapped MessageBodyWriter.writeTo method.

getEntity

Object getEntity()

Get object to be written as HTTP entity.

Returns:

object to be written as HTTP entity.

setEntity

void setEntity(Object entity)

Update object to be written as HTTP entity.

Parameters:

entity - new object to be written.

getOutputStream

OutputStream getOutputStream()

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

Returns:

output stream for the object to be written.

setOutputStream

void setOutputStream(OutputStream os)

Set a new output stream for the object to be written. For example, by wrapping it with another output stream. The runtime is responsible for closing the output stream that is set.

Parameters:

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

getHeaders

MultivaluedMap<String,Object> getHeaders()

Get mutable map of HTTP headers.

Returns:

map of HTTP headers.
