public interface PropertyNamesIteratorOperations
A PropertySet
maintains a set of name-value pairs.
The get_all_property_names
operation returns a sequence
of names (PropertyNames
). If there are additional names,
the get_all_property_names
operation returns an object
supporting the PropertyNamesIterator
interface with the
additional names.
The PropertyNamesIterator
interface allows a client to
iterate through the names using the next_one
or
next_n
operations.
Method Summary | |
---|---|
void |
destroy()
The destroy operation destroys the iterator. |
boolean |
next_n(int how_many,
PropertyNamesHolder property_names)
The next_n operation returns true
if an item exists at the current position in the iterator and
the how_many parameter was set greater than zero. |
boolean |
next_one(org.omg.CORBA.StringHolder property_name)
The next_one operation returns true
if an item exists at the current position in the iterator with
an output parameter of a property. |
void |
reset()
The reset operation resets the position in an iterator to the first property, if one exists. |

void reset()
boolean next_one(org.omg.CORBA.StringHolder property_name)
next_one
operation returns true
if an item exists at the current position in the iterator with
an output parameter of a property. A return of false
signifies no more items in the iterator.
property_name
- the retrieved property name is returned in
the output parameter.
true
if a property name was retrieved.boolean next_n(int how_many, PropertyNamesHolder property_names)
next_n
operation returns true
if an item exists at the current position in the iterator and
the how_many
parameter was set greater than zero.
The output is a properties sequence with at most the
how_many
number of properties. A return of
false
signifies no more items in the iterator.
how_many
- the number of property names to retrieve.property_names
- the sequence of retrieved property
names is returned in the output parameter.
true
if at least one property name was retrieved.void destroy()
destroy
operation destroys the iterator.
