checkSize
Description copied from interface:HttpData
Check if the new size is not reaching the max limit allowed. The limit is always computed in terms of bytes.- Specified by:
checkSize
in interfaceHttpData
- Throws:
IOException

definedLength
public long definedLength()Description copied from interface: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 oneFileUpload
or any known bigAttribute
.- Specified by:
definedLength
in interfaceHttpData
- Returns:
- the defined length of the HttpData
