Example 2: Traversing Iterators

SE_Status_Code SE_GetNextObject

(

SE_Iterator iterator,

SE_Object *next_object,

SE_Object *link_object

);

• Objects can be sequentially retrieved from Iterators using the API function SE_GetNextObject().

• SE_Objects are allocated by the API and must be freed.

• If the component relationship has a link object, the object is returned in the third argument.

• Returns SE_STAT_CODE_NO_OBJECT at the end of the Iterator.

• SE_GetIterationLengthRemaining() returns the number of objects left in an Iterator.

SE_Status_Code SE_GetIterationLengthRemaining

(

SE_Iterator iterator,

SE_Integer_Unsigned *num_remaining_objects

);
