Constructor & Destructor Documentation

ImageTransport ( const std::string &  streamname  )  [explicit]

Standard constructor.

Automatically generates a (hopefully) unique global name. If two of the same (consumer) binaries are running, it *will* fail. This is the only constructor you should use for suppliers.

Definition at line 37 of file ImageTransport.cpp.

References ImageTransport::init(), Capability::m_haveGlobalname, and WURDE::STRAT_NORMAL.

ImageTransport ( const ConnectionStrategy strategy,
const std::string &  gblName 
)

Auto-wiring constructor.

Submits a request to MCP for a stream to connect to, based on global name. ConnectionStrategy should be auto for now.

Definition at line 44 of file ImageTransport.cpp.

References ImageTransport::init(), Capability::m_haveGlobalname, Capability::m_haveStream, and WURDE::STRAT_NORMAL.

ImageTransport ( const std::string &  streamname,
const std::string &  gblName 
)

Like the standard constructor, but explicitly sets the global name.

Use this when starting multiple instances of the same binary, so that each instance can be assigned a separate name.

void setAutoPing ( const bool &  val  )  [virtual]

Sets the state of the auto-ping function.

If true, consumers will automatically send out a blank MESSAGE_PING to the stream source, and suppliers will automatically filter out these requests and send a copy of the last published info and data.

Should consumers be set up to send out this request on a regular basis?
