* Represents a property set in the Horrible Property Set Format (HPSF). These

|

|

* <p>{@link PropertySetFactory#create} does its work by calling one
|

* of the constructors {@link PropertySet#PropertySet(InputStream)} or
|
||||
* {@link PropertySet#PropertySet(byte[])}. If the constructor's
|
||||
* argument is not in the Horrible Property Set Format, i.e. not a

|

* <p>A {@link PropertySet} has a list of {@link Section}s, and each

* #getSections} to retrieve the {@link Section}s, then call {@link
|
||||
* Section#getProperties} for each {@link Section} to get hold of the
|
||||
* {@link Property} arrays.</p> Since the vast majority of {@link
|
||||
* PropertySet}s contains only a single {@link Section}, the
|
||||
* convenience method {@link #getProperties} returns the properties of
|
||||
* a {@link PropertySet}'s {@link Section} (throwing a {@link
