All Methods Instance Methods Default Methods
Modifier and Type	Method	Description
`default long`	`getLength()`	Called from native when the processing needs to know the length of the stream.
`default boolean`	`resetPosition()`	Called from native when the processing needs the stream to rewind itself back to its beginning.

- Method Detail
  - sendRequestBody
```
default boolean sendRequestBody(java.nio.ByteBuffer bodyBytesOut)
```
    Called from Native when the Http Request has a Body (Eg PUT/POST requests). Note that this function may be called many times as Native sends the Request Body. Do NOT keep a reference to this ByteBuffer past the lifetime of this function call. The CommonRuntime reserves the right to use DirectByteBuffers pointing to memory that only lives as long as the function call.
    
    Parameters:
    
    bodyBytesOut - The Buffer to write the Request Body Bytes to.
    
    Returns:
    
    True if Request body is complete, false otherwise.
  - resetPosition
```
default boolean resetPosition()
```
    Called from native when the processing needs the stream to rewind itself back to its beginning. If the stream does not support rewinding or the rewind fails, false should be returned Signing requires a rewindable stream, but basic http does not.
    
    Returns:
    
    True if the stream was successfully rewound, false otherwise.
  - getLength
```
default long getLength()
```
    Called from native when the processing needs to know the length of the stream. If the stream does not know/support length, 0 should be returned. Signing requires a rewindable stream, but basic http does not.
    
    Returns:
    
    Stream length, or 0 if unknown stream or length is unsupported
