# XPRMArray Properties

The XPRMArray type exposes the following members.

Properties

| Name | Description
--- | --- | ---
| Dim | Array dimensions; number indices required to access an array cell
| FirstIndex | Index of the first cell of the array.
| FirstTEIndex | Index of the first defined cell of the array. Dynamic arrays do not necessarily have a defined cell for each index.
| IndexSets | Sets indexing the array. When indices are given to the array in other functions, we use indexes into the index sets - ie if there are two index sets {2,3,4} and {"a", "b", "c"), then the array position [2,"c"] will be passed to Get(Int32) as an array of two integers: [1,3], because "2" is the first element of the first index set, and "c" is the third element of the second index set.
| Indices | A list containing all the index positions in the array - each index position is given as an int[].
| IsDynamic | Check whether the array is dynamic.
| IsEmpty | Check whether the array is empty.
| IsInitialised | Check whether the array has been initialised. Objects are initialised during model execution. Trying to access a Mosel object that has not been created will result on an exception. (Overrides XPRMValueIsInitialised)
| LastIndex | Index of the last cell of the array.
| Model | Used to fetch the XPRM model to which this object belongs, or else 'null' if there is no model anywhere among this Object's ancestors. (Inherited from XPRMObjectBase)
| Owner | Used to fetch the XPRM object to which this object belongs (Inherited from XPRMObjectBase)
| Size | The total number of elements in the array
| StructCode | (Inherited from XPRMTypedObject)
| StructName | (Inherited from XPRMTypedObject)
| TEIndices | A list containing the index positions of all the defined cells in the array - each index position is given as an int[].
| Type | (Inherited from XPRMTypedObject)
| TypeCode | (Inherited from XPRMTypedObject)
| TypeName | (Inherited from XPRMTypedObject)
