HttpEntity
Repeatable
entities are expected
to create a new instance of InputStream
for each invocation
of this method and therefore can be consumed multiple times.
Entities that are not repeatable
are expected
to return the same InputStream
instance and therefore
may not be consumed more than once.
If this entity belongs to an incoming HTTP message, calling
InputStream.close()
on the returned InputStream
will
try to consume the complete entity content to keep the connection
alive. In cases where this is undesired, e.g. when only a small part
of the content is relevant and consuming the complete entity content
would be too inefficient, only the HTTP message from which
this entity was obtained should be closed (if supported).
IMPORTANT: Please note all entity implementations must ensure that
all allocated resources are properly deallocated after
the InputStream.close()
method is invoked.
