Method Detail

destroy

void destroy()
             throws AoException

(19001) Destroy the iterator and free the associated memory.

Throws:

AoException - with the following possible error codes: AO_CONNECTION_LOST AO_IMPLEMENTATION_PROBLEM AO_NOT_IMPLEMENTED AO_NO_MEMORY AO_SESSION_NOT_ACTIVE

getCount

int getCount()
             throws AoException

(19002) Get the total number of elements accessible by the iterator.

Returns:

The number of elements accessible by the iterator.

Throws:

AoException - with the following possible error codes: AO_CONNECTION_LOST AO_IMPLEMENTATION_PROBLEM AO_NOT_IMPLEMENTED AO_NO_MEMORY AO_SESSION_NOT_ACTIVE

nextN

NameValueUnit[] nextN(int how_many)
                      throws AoException

(19003) Get the next n elements from the NameValueUnit sequence. In case there are less elements available than requested, only as many as are available will be returned; if there is none left an empty list is returned.

Parameters:

how_many - The number of requested elements.

Returns:

The next n NameValueUnit tuples from the NameValueUnit tuple sequence.

Throws:

AoException - with the following possible error codes: AO_BAD_PARAMETER AO_CONNECTION_LOST AO_IMPLEMENTATION_PROBLEM AO_NOT_IMPLEMENTED AO_NO_MEMORY AO_SESSION_NOT_ACTIVE

nextOne

NameValueUnit nextOne()
                      throws AoException

(19004) Get the next element from the NameValueUnit sequence. In case no element is available a NIL object is returned.

Returns:

The next NameValueUnit tuple from the NameValueUnit tuple sequence.

Throws:

AoException - with the following possible error codes: AO_CONNECTION_LOST AO_IMPLEMENTATION_PROBLEM AO_NOT_IMPLEMENTED AO_NO_MEMORY AO_SESSION_NOT_ACTIVE

reset

void reset()
           throws AoException

(19005) Reset the internal pointer in the element sequence to the first element.

Throws:

AoException - with the following possible error codes: AO_CONNECTION_LOST AO_IMPLEMENTATION_PROBLEM AO_NOT_IMPLEMENTED AO_NO_MEMORY AO_SESSION_NOT_ACTIVE
