Method Detail

getContentLength

public long getContentLength()

Description copied from interface: HttpEntity

Tells the length of the content, if known.

Returns:

the number of bytes of the content, or a negative number if unknown. If the content length is known but exceeds Long.MAX_VALUE, a negative number is returned.

getContent

public java.io.InputStream getContent()
                               throws java.io.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:

java.io.IOException - if the stream could not be created

HttpEntity.isRepeatable()

isRepeatable

public 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.

Returns:

true if the entity is repeatable, false otherwise.

writeTo

public void writeTo(java.io.OutputStream outstream)
             throws java.io.IOException

Description copied from interface: HttpEntity

Writes the entity content out to the output stream.

IMPORTANT: Please note all entity implementations must ensure that all allocated resources are properly deallocated when this method returns.

Parameters:

outstream - the output stream to write entity content to

Throws:

java.io.IOException - if an I/O error occurs

isStreaming

public 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
