Detailed Description

Child class of CThttp_base; uses HttpClient to perform asynchronous HTTP PUT.

CThttp_HttpClient

This class has been tested and works, but is still somewhat "experimental"; for example, the method used in closeHttpClient() to wait for pending requests before closing the connection is kludgey (there's probably a better way to do this).

Constructor & Destructor Documentation

CThttp_HttpClient()

CTlib.CThttp_HttpClient.CThttp_HttpClient ( String  baseCTOutputFolderI, int  numBlocksPerSegmentI, bool  bOutputTimesAreMillisI, bool  bPackI, bool  bZipI, String  ctWebHostI = "http://localhost:8000"  )

inline

Constructor.

Calls the constructor in the base class.

Parameters

baseCTOutputFolderI	The output source name along with optional additional sub-directory layers. Should be a relative folder path, since the absolute location where data will be written is determined by the HTTP server.
numBlocksPerSegmentI	Number of blocks per segment in the source folder hierarchy. Use 0 to not include a segment layer.
bOutputTimesAreMillisI	Output times should be in milliseconds? Needed if blocks are written (i.e., flush() is called) at a rate greater than 1Hz.
bPackI	Pack data at the block folder level? Packed data times are linearly interpolated from the block start time to the time of the final datapoint in the packed channel.
bZipI	ZIP data at the block folder level?
ctWebHostI	Optional argument; this is the web host data will be PUT to.

Member Function Documentation

writeToStream()

override void CTlib.CThttp_HttpClient.writeToStream ( String  outputDirI, String  chanNameI, byte []  dataI  )

inlineprotectedvirtual

Write data to the channel using HTTP PUT.

Parameters

outputDirI	Where the given data should be put on the server.
chanNameI	Channel name.
dataI	The data to PUT.

Reimplemented from CTlib.CThttp_base.
