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

The heartbeat function of the reader class.

As long as the command that is returned is not equal to OmniPvdCommand::eINVALID, then one can safely extract the data fields from the command.

Returns: The command enum type

virtual OmniPvdVersionType getMajorVersion() = 0

Returns the major version of the stream.

Returns: The major version

virtual OmniPvdVersionType getMinorVersion() = 0

Returns the minor version of the stream.

Returns: The minor version

virtual OmniPvdVersionType getPatch() = 0

Returns the patch number of the stream.

Returns: The patch value

virtual OmniPvdContextHandle getContextHandle() = 0
