bool gazebo::util::LogPlay::GetChunk ( unsigned int  _index,
std::string &  _data 
)

Get data for a particular chunk index.

Parameters
[in]_indexIndex of the chunk.
[out]_dataStorage for the chunk's data.
Returns
True if the _index was valid.
unsigned int gazebo::util::LogPlay::GetChunkCount ( ) const

Get the number of chunks (steps) in the open log file.

Returns
The number of recorded states in the log file.
std::string gazebo::util::LogPlay::GetEncoding ( ) const

Get the type of encoding used for current chunck in the open log file.

Returns
The type of encoding. An empty string will be returned if LogPlay::Step has not been called at least once.
std::string gazebo::util::LogPlay::GetGazeboVersion ( ) const

Get the Gazebo version number of the open log file.

Returns
The Gazebo version of the open log file. Empty string if a log file is not open.
std::string gazebo::util::LogPlay::GetHeader ( ) const

Get the header that was read from a log file.

Should call LogPlay::Open first.

Returns
Header of the open log file.
std::string gazebo::util::LogPlay::GetLogVersion ( ) const

Get the log version number of the open log file.

Returns
The log version of the open log file. Empty string if a log file is not open.
uint32_t gazebo::util::LogPlay::GetRandSeed ( ) const

Get the random number seed of the open log file.

Returns
The random number seed the open log file. The current random number seed, as defined in math::Rand::GetSeed.
bool gazebo::util::LogPlay::IsOpen ( ) const

Return true if a file is open.

Returns
True if a log file is open.
void gazebo::util::LogPlay::Open ( const std::string &  _logFile)

Open a log file for reading.

Open a log file that was previously recorded.

Parameters
[in]_logFileThe file to load
Exceptions
