Constructor Detail

BasicHttpEntity

public BasicHttpEntity()

Creates a new basic entity. The content is initially missing, the content length is set to a negative number.

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.lang.IllegalStateException

Obtains the content, once only.

Returns:

the content, if this is the first call to this method since setContent has been called

Throws:

java.lang.IllegalStateException - if the content has not been provided

HttpEntity.isRepeatable()

isRepeatable

public boolean isRepeatable()

Tells that this entity is not repeatable.

Returns:

false

setContentLength

public void setContentLength(long len)

Specifies the length of the content.

Parameters:

len - the number of bytes in the content, or a negative number to indicate an unknown length

setContent

public void setContent(java.io.InputStream instream)

Specifies the content.

Parameters:

instream - the stream to return with the next call to getContent

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
