  - definedLength
```
public long definedLength()
```
    从接口复制的说明: HttpData
    
    Returns the defined length of the HttpData. If no Content-Length is provided in the request, the defined length is always 0 (whatever during decoding or in final state). If Content-Length is provided in the request, this is this given defined length. This value does not change, whatever during decoding or in the final state. This method could be used for instance to know the amount of bytes transmitted for one particular HttpData, for example one FileUpload or any known big Attribute.
    
    指定者:
    
    definedLength 在接口中 HttpData
    
    返回:
