OmniPvdReader
Defined in pvdruntime/include/OmniPvdReader.h
-
class OmniPvdReader
Used to read debug information from an OmniPvdReadStream.
Using the getNextCommand function in a while loop for example one can traverse the stream one command after another. Given the command, different functions below will be available.
Using the OmniPvdCommand::Enum one can determine the type of command and like that use the appropriate get functions to extract the payload from the command.
Public Functions
-
inline virtual ~OmniPvdReader()
-
virtual void setLogFunction(OmniPvdLogFunction logFunction) = 0
Sets the log function to print the internal debug messages of the OmniPVD Reader instance.
- Parameters
logFunction – The function pointer to receive the log messages
-
virtual void setReadStream(OmniPvdReadStream &stream) = 0
Sets the read stream that contains the OmniPVD API command stream.
- Parameters
stream – The OmniPvdReadStream that holds the stream of API calls/notifications
-
virtual bool startReading(OmniPvdVersionType &majorVersion, OmniPvdVersionType &minorVersion, OmniPvdVersionType &patch) = 0
Extracts the versions from the binary file to read and tests if the file is older or equal to that of the reader.
- Parameters
majorVersion – The major versions of the stream
minorVersion – The minor versions of the stream
patch – The patch number of the stream
- Returns
If the reading was possible to start or not
-
virtual OmniPvdCommand::Enum getNextCommand() = 0
