Method Detail

getData

org.epics.util.array.ListNumber getData()

Description copied from interface: Array

Return the object containing the array data.

This method will either return a List or a ListNumber depending of the array type. A collection is returned, instead of an array, so that the type implementation can be immutable or can at least try to prevent modifications. ListNumber has also several advantages over the Java arrays, including the ability to iterate the list regardless of numeric type.

If a numeric array is actually needed, refer to CollectionNumbers.

Specified by:

getData in interface Array

Returns:

the array data

getDimensionDisplay

List<ArrayDimensionDisplay> getDimensionDisplay()

Returns the boundaries of each cell.

Returns:

the dimension display; can't be null
