true
until the
content has been consumed, false
afterwards.
Self-contained entities should return false
.
Wrapping entities should delegate this call to the wrapped entity.
getContent
has been read to EOF,
or after consumeContent
has been called.
If a streamed entity can not detect whether the stream has been
read to EOF, it should return true
until
consumeContent
is called.
isStreaming
in interface HttpEntity
true
if the entity content is streamed and
not yet consumed, false
