Example 2: Traversing Iterators

SE_STATUS_CODE_ENUM 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 and must be freed.

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

• Returns SE_NO_OBJECT at the end of the Iterator.

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

SE_STATUS_CODE_ENUM SE_GetIterationLengthRemaining

(

SE_ITERATOR Iterator,

SE_UINT32 *num_remaining_objects

);
