public class CustomProperties extends HashMap
Maintains the instances of CustomProperty that belong to a
DocumentSummaryInformation. The class maintains the names of the
custom properties in a dictionary. It implements the Map interface
and by this provides a simplified view on custom properties: A property's
name is the key that maps to a typed value. This implementation hides
property IDs from the developer and regards the property names as keys to
typed values.
While this class provides a simple API to custom properties, it ignores the fact that not names, but IDs are the real keys to properties. Under the hood this class maintains a 1:1 relationship between IDs and names. Therefore you should not use this class to process property sets with several IDs mapping to the same name or with properties without a name: the result will contain only a subset of the original properties. If you really need to deal such property sets, use HPSF's low-level access methods.
An application can call the isPure method to check whether a
property set parsed by CustomProperties is still pure (i.e.
unmodified) or whether one or more properties have been dropped.
This class is not thread-safe; concurrent access to instances of this class must be syncronized.

public Object put(Object name, Object customProperty) throws ClassCastException
Puts a CustomProperty into this map. It is assumed that the
CustomProperty already has a valid ID. Otherwise use
put(CustomProperty).
put in interface Mapput in class HashMapClassCastExceptionprivate Object put(CustomProperty customProperty) throws ClassCastException
Puts a CustomProperty that has not yet a valid ID into this
map. The method will allocate a suitable ID for the custom property:
If there is already a property with the same name, take the ID of that property.
Otherwise find the highest ID and use its value plus one.
