InputStreamEntity

public InputStreamEntity(InputStream instream,
                         long length)

Creates an entity with a specified content length.

Parameters:

instream - input stream

length - of the input stream, -1 if unknown

Throws:

IllegalArgumentException - if instream is null

InputStreamEntity

public InputStreamEntity(InputStream instream,
                         org.apache.http.entity.ContentType contentType)

Creates an entity with a content type and unknown length. Equivalent to new InputStreamEntity(instream, -1, contentType).

Parameters:

instream - input stream

contentType - content type

Throws:

IllegalArgumentException - if instream is null

InputStreamEntity

public InputStreamEntity(InputStream instream,
                         long length,
                         org.apache.http.entity.ContentType contentType)

Parameters:

instream - input stream

length - of the input stream, -1 if unknown

contentType - for specifying the Content-Type header, may be null

Throws:

IllegalArgumentException - if instream is null

Method Detail

isRepeatable

public boolean isRepeatable()

getContentLength

public long getContentLength()

Returns:

the content length or -1 if unknown

getContent

public InputStream getContent()
                       throws IOException

Throws:

IOException

writeTo

public void writeTo(OutputStream outstream)
             throws IOException

Writes bytes from the InputStream this entity was constructed with to an OutputStream. The content length determines how many bytes are written. If the length is unknown (-1), the stream will be completely consumed (to the end of the stream).

Throws:

IOException

isStreaming

public boolean isStreaming()
