List of all members.

Public Member Functions

 FlowData ()
 initializes the channel storage
 ~FlowData ()
 destoys all created channels
bool loadDataset (string filename, bool bigEndian)
 Loads a dataset, returns true if everything successful. You have to specify the byte order used in the data.
int getNumTimesteps ()
 Returns the number of timesteps.
int getNumChannels ()
int createChannel ()
 creates a new channel and returns it's address in the channels array (line 28)
void deleteChannel (int i)
 deletes the channel and all it's data at given adress
FlowChannelgetChannel (int i)
 returns a pointer to the instance of channel at given adress. This is the only way to access the channels storage (at line 28)
int createChannelValue (int ch)
int createChannelGeometry (int dimension)
 creates a new channel containing the geometrical information of the given dimension (x = 0, y = 1). Returns address of the created channel in the channels array (line 28)
int createChannelVectorLength (int chX, int chY, int chZ=-1)
 creates a new channel containing the vector lengths for the given channels (channels given by IDs). Returns address of the created channel in the channels array (line 28)
int createChannelVectorLength (FlowChannel *chX, FlowChannel *chY, FlowChannel *chZ=NULL)
 creates a new channel containing the vector lengths for the given channels (channels given by reference). Returns address of the created channel
void getGeometry (int &x, int &y)

Private Attributes

bool loaded
 Is there any data loaded?
int timesteps
 Number of timesteps.
FlowGeometry geometry
 Stores the underlying geometry.
bool freeChannel [max_channels]
 is the channel slot free?
FlowChannelchannels [max_channels]
 stores the values of data channels for one time step. For time-dependent data, the best solution is to create a separate class handling channels in one timestep and to instanciate this class for all timesteps.
int numofChannels
