An eye movement trace.
This class encapsulates a simple eye movement trace and provides I/O functions.

| EyeTrace::~EyeTrace | ( | ) |
Destructor.

| std::string EyeTrace::basename | ( | ) | const |
Get filename, without extension if any.
Definition at line 414 of file EyeTrace.C.
Get our display color.

| rutz::shared_ptr< EyeData > EyeTrace::data | ( | const size_t | index | ) | const |
Get the data for a given index.
Note that this will throw a fatal error if we don't have data for that index; so be sure to check with hasData() first.

| std::string EyeTrace::filename | ( | ) | const |
Get filename.

| bool EyeTrace::hasData | ( | const size_t | index | ) | const |
Do we have a sample for the given index?
This will return true as long as the index is not past the available amount of data.
Definition at line 216 of file EyeTrace.C.
| bool EyeTrace::hasData | ( | const size_t | index, | |
| const SimTime & | t | |||
| ) | const |
Did sample of given index happen before given time?
Typically one would keep incrementing the index until we return false here, at which point it would be time to increment the time. Note that we will always return false after the index gets past all available samples in the trace.

| size_t EyeTrace::numEvents | ( | ) | const |
Get number of parsed events (if any).
