Method Detail

isRepeatable

public final boolean isRepeatable()

Description copied from interface: HttpEntity

Tells if the entity is capable of producing its data more than once. A repeatable entity's getContent() and writeTo(OutputStream) methods can be called more than once whereas a non-repeatable entity's can not.

Specified by:

isRepeatable in interface HttpEntity

Overrides:

isRepeatable in class AbstractHttpEntity

Returns:

true if the entity is repeatable, false otherwise.

getContentLength

public final long getContentLength()

Description copied from interface: EntityDetails

Returns length of the entity, if known.

getContent

public final InputStream getContent()
                             throws IOException

Description copied from interface: HttpEntity

Returns a content stream of the entity. 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.

IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated after the InputStream.close() method is invoked.

Returns:

content stream of the entity.

Throws:

IOException - if the stream could not be created

HttpEntity.isRepeatable()

isStreaming

public final boolean isStreaming()

Description copied from interface: HttpEntity

Tells whether this entity depends on an underlying stream. Streamed entities that read data directly from the socket should return true. Self-contained entities should return false. Wrapping entities should delegate this call to the wrapped entity.

Returns:

true if the entity content is streamed, false otherwise

close

public final void close()
                 throws IOException

Throws:

IOException
