Method Detail

resolveCursorStreamProvider

public org.mule.runtime.api.streaming.bytes.CursorStreamProvider resolveCursorStreamProvider(InputStream value)

Description copied from interface: StreamingHelper

If the value is a repeatable streaming resource such as InputStream, CursorStream, then an equivalent CursorStreamProvider is returned. For CursorStream values, the same CursorStreamProvider that already owns that CursorStream is used. For other streaming values, the operation's repeatable streaming strategy will be used. If that strategy doesn't apply (e.g: the operation returns a PagingProvider but the streaming resource is an InputStream), then the system's default matching strategy will be used instead.

Specified by:

resolveCursorStreamProvider in interface StreamingHelper

Parameters:

value - a value which may be a repeatable streaming resource.

Returns:

a CursorProvider or the same input value
