#!F-adobe-helvetica-medium-r-normal--18*
#!N
#!CSeaGreen #!N #!Rall1069 Generic Operations #!N #!EC #!N #!N Each
Array #!F-adobe-times-bold-r-normal--18* a #!EF contains some number of items #!F-adobe-times-medium-i-normal--18* n
#!EF (numbered #!F-adobe-times-medium-i-normal--18* 0 #!EF to #!F-adobe-times-medium-i-normal--18* n-1 #!EF ). Each
item consists of a fixed number of elements of one type,
specified when the array is created (see #!Ltipes,dxall1101 s TIPES #!EL for the constants
used to specify types). Note: The routines listed in this subsection
apply to both compact and irregular Arrays. #!N #!I0 #!N #!N
#!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* Class DXGetArrayClass() #!EF #!EF #!I50 #!N Returns
the subclass of an Array Object. See #!Ldxgac,dxall1218 h DXGetArrayClass #!EL . #!N #!I0
#!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* Array DXGetArrayInfo() #!EF #!EF #!I50 #!N Returns the
number of items, type, category, rank, and shape of an Array.
See #!Ldxgai,dxall1222 h DXGetArrayInfo #!EL . (For information on rank and shape, see #!Larrays,dxall252 h Arrays #!EL
in IBM Visualization Data Explorer User's Guide.) #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* Array DXTypeCheck() #!EF #!N Array DXTypeCheckV(); #!EF #!I50 #!N Check
that an Array matches a set of specifications. See #!Ldxtcv,dxall1402 h DXTypeCheck, DXTypeCheckV #!EL .
#!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* Pointer DXGetArrayData() #!EF #!EF #!Rpgdxgad #!I50
#!N Returns a pointer to the start of a global memory
area containing the items constituting the data stored in an Array.
See #!Ldxgad,dxall1219 h DXGetArrayData #!EL . #!N Note: To reduce memory requirements, it is
preferable, where possible, to recognize compact arrays with #!F-adobe-times-bold-r-normal--18* DXGetArrayClass() #!EF
, and not to expand them by calling #!F-adobe-times-bold-r-normal--18* DXGetArrayData() #!EF
. An alternative is the set of Array-handling routines described in
#!Larhand,dxall1073 h Array Handling #!EL . #!N #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18* #!F-adobe-times-bold-r-normal--18* int DXGetItemSize() #!EF
#!EF #!I50 #!N Returns the size in bytes of each individual
item of an Array. See #!Ldxgis,dxall1245 h DXGetItemSize #!EL . #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* Pointer DXGetArrayDataLocal() #!EF #!EF #!I50 #!N Returns a pointer to
the start of memory of a local copy of the data
stored in an Array. See #!Ldxgadl,dxall1220 h DXGetArrayDataLocal #!EL . #!N #!I0 #!N #!F-adobe-times-bold-r-normal--18*
#!F-adobe-times-bold-r-normal--18* Array DXFreeArrayDataLocal() #!EF #!EF #!I50 #!N Frees space allocated by
