Examples of ArrayStructure

ucar.ma2.ArrayStructure
Superclass for implementations of Array of StructureData.
The general way to access data in an ArrayStructure is to use
```
 StructureData getStructureData(Index index).
```
For 1D arrays (or by caclulating your own recnum for nD arrays), you can also use:
```
 StructureData getStructureData(int recnum).
```
Once you have a StructureData object, you can access data in a general way by using:
```
 Array StructureData.getArray(Member m) 
```
When dealing with large arrays of Structures, there can be significant overhead in using the generic interfaces. A number of convenience routines may be able to avoid extra Object creation, and so are recommended for efficiency. The following may avoid the overhead of creating the StructureData object:
```
 Array getArray(int recno, StructureMembers.Member m) 
```
The following can be convenient for accessing all the data in the ArrayStructure for one member, but its efficiency depends on the implementation:
```
 Array getMemberArray(StructureMembers.Member m) 
```
These require that you know the data types of the member data, but they are the most efficent:
```
 getScalarXXX(int recnum, Member m) getJavaArrayXXX(int recnum, Member m) 
```
where XXX is Byte, Char, Double, Float, Int, Long, Short, or String. For members that are themselves Structures, the equivilent is:
```
 StructureData getScalarStructure(int recnum, Member m) ArrayStructure getArrayStructure(int recnum, Member m) 
```
These will return any compatible type as a double or float, but will have extra overhead when the types dont match:
```
 convertScalarXXX(int recnum, Member m) convertJavaArrayXXX(int recnum, Member m) 
```
where XXX is Double or Float @author caron @see Array @see StructureData
