progress property

The approximate fraction of pyramid build work completed.

Progress is reported as a value from 0.0 to 1.0 inclusive. A value of 0.0 indicates that no progress has been made, and a value of 1.0 indicates that the build completed successfully.

The value may be approximate and may not change for every unit of work completed. When this value changes, the BuildRasterPyramidsOperation.onProgressChanged event is fired. If a build fails or is canceled, the value remains at the last reported progress value.
