Constructor Detail

ProtoHttpContent

public ProtoHttpContent(com.google.protobuf.MessageLite message)

Parameters:

message - message to serialize

Method Detail

getLength

public long getLength()
               throws IOException

Description copied from class: AbstractHttpContent

Default implementation calls AbstractHttpContent.computeLength() once and caches it for future invocations, but subclasses may override.

Specified by:

getLength in interface HttpContent

Overrides:

getLength in class AbstractHttpContent

Throws:

IOException

writeTo

public void writeTo(OutputStream out)
             throws IOException

Description copied from interface: StreamingContent

Writes the byte content to the given output stream.

Implementations must not close the output stream, and instead should flush the output stream. Some callers may assume that the output stream has not been closed, and will fail to work if it has been closed.

Parameters:

out - output stream

Throws:

IOException

getMessage

public final com.google.protobuf.MessageLite getMessage()

Returns the message to serialize.

setMediaType

public ProtoHttpContent setMediaType(HttpMediaType mediaType)

Description copied from class: AbstractHttpContent

Sets the media type to use for the Content-Type header, or null if unspecified.

This will also overwrite any previously set parameter of the media type (for example "charset"), and therefore might change other properties as well.

Overrides:

setMediaType in class AbstractHttpContent
