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	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
FlowChannel *	getChannel (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	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
int	getDimX ()
int	getDimY ()
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?
FlowChannel *	channels [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.

Member Function Documentation

int FlowData::createChannel

(

)

creates a new channel and returns it's address in the channels array (line 28)

int FlowData::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 FlowData::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

int FlowData::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)

void FlowData::deleteChannel

(

int

i

)

deletes the channel and all it's data at given adress

FlowChannel * FlowData::getChannel

(

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 FlowData::getDimX

)

int FlowData::getDimY

(

)

int FlowData::getNumTimesteps

(

)

Returns the number of timesteps.

bool FlowData::loadDataset	(	string	filename,
		bool	bigEndian
	)

Loads a dataset, returns true if everything successful. You have to specify the byte order used in the data.

Member Data Documentation

FlowChannel* FlowData::channels[max_channels] [private]

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.

bool FlowData::freeChannel[max_channels] [private]

is the channel slot free?

FlowGeometry FlowData::geometry [private]

Stores the underlying geometry.

bool FlowData::loaded [private]

Is there any data loaded?

int FlowData::timesteps [private]

Number of timesteps.
