Class Description
- Generates a user`s sequence on a attribute of a specified device. The sequence
- generated is gave by a command. It can be generated once, n times or indefinitly (until stop by user). Be aware that the timings for the generation are software (so not very precise).

Commands:
| Name | Description |
|---|---|
| StateInput: DevVoid Output: State |
This command gets the device state (stored in its device_state data member) and returns it to the caller. |
| StatusInput: DevVoid Output: DevString |
This command gets the device status (stored in its device_status data member) and returns it to the caller. |
| StartInput: DevVoid Output: DevVoid |
Start the sequence generation. |
| StopInput: DevVoid Output: DevVoid |
Stop the sequence generation. |
| PauseInput: DevVoid Output: DevVoid |
Pause the sequence generation. |
| ResumeInput: DevVoid Output: DevVoid |
Restart the sequence generation previoulsy paused (with Pause command). |
| LoadSequenceValuesInput: DevVarDoubleArray Output: DevVoid |
Give the device one sequence to generate. |
| LoadWaitingTimesInput: DevVarDoubleArray Output: DevVoid |
Give the device the waiting times of the sequence. |

Properties:
| Name | Description |
|---|---|
| AttributeProxyWriteDevString | The name of the attribute on which to generate the sequence. |
| AttributeProxyReadDevString | The name of the attribute used to verify that the written value of AttributeProxyWrite has been reached. |
| DeltaDevDouble | The minimum acceptable difference between the value AttributeProxyWrite and AttributeProxyRead. |
| TimeoutDevDouble | The time in seconds to wait for AttributeProxyRead has reached AttributeProxyWrite. |
| PollingPeriodDevDouble | The period in seconds at which AttributeProxyRead is read to check that it has reached the written value. |
| IterationsDevLong | The number of times the given sequence that will be generated once Start command is called. It can be 1..n or 0 to generate it indefinilty (until Stop command is called). |
| SequenceSizeDevLong | The number of elements in a sequence. |
| FilePathDevString | Path where the sequence files can be saved or loaded. Files` name, for a device named A/B/C, are: - A#B#C_SequenceValues.dat for sequence values, - A#B#C_WaitingTimes.dat for waiting times. |
