+/**
+ * This class is a container for interfaces.
+ *
+ * It is intended to be used as storage for UNO interface of a specific type.
+ * The client has to ensure that the container contains only elements of the same
+ * type. If one needs to store different types, then one uses OMultiTypeInterfaceContainer.
+ * When the client calls disposeAndClear, the contained objects are queried for
+ * com.sun.star.lang.XEventListener and disposing is called. Afterwards
+ * the list cannot be used anymore.
+ *
+ * This list does not allow null values.
+ * All methods are thread-safe. The same holds true for
+ * iterators, issued by this class. Several iterators can exist at the same time and can also
+ * be modified (java.util.ListIterator.add, java.util.ListIterator.remove etc.). To make this work,
+ * the InterfaceContainer provides the iterators with copies of the list's data.
+ * The add and remove calls on the iterator modify the data in the iterator's list as well as
+ * in InterfaceContainer. Modification on InterfaceContainer, however, are not
+ * synchronized with existing iterators. For example
+ * <pre>
+ * InterfaceContainer cont= new InterfaceContainer();
+ * ListIterator it= cont.listIterator();
+ *
+ * cont.add( someInterface);
+ * // one cannot obtain someInterface through iterator it,
+ * // instead get a new iterator
+ * it= cont.listIterator();
+ * // it now keeps a fresh copy of cont and hence contains someInterface
+ *
+ * // Adding an interface on the iterator will cause the interface also to be added
+ * // to InterfaceContainer
+ * it.add( someOtherInterface);

+ *
+ *  The add and remove methods of an iterator work on a particular location within a list,
+ *  dependent on what the value of the iterator's cursor is. After the call the value at the
+ *  appropriate position has been modified. Since the iterator received a copy of InterfaceContainer's
+ *  data, InterfaceContainer may have been modified (by List methods or through other iterators).
+ *  Therefore both data sets may not contain the same elements anymore. Consequently, a List method
+ *  that modifies data, does not modify InterfaceContainer's data at a certain index
+ *  (according to the iterators cursor). Instead, new elements are added at the end of list. When
+ *  Iterator.remove is called, then the first occurrence of that element in InterfaceContainer
+ *  is removed.
+ *  ListIterator.set is not supported.
+ *
+ * A lot of  methods resemble those of the  to java.util.List interface, although
+ * this class does not implement it. However, the list iterators returned, for example by
+ * the listIterator method implement the java.util.ListIterator interface.
+ * Implementing the List interface would mean to support all none - optional methods as
+ * prescribed by the interface declaration. Among those is the subList method which returns
+ * a range of values of the list's data wrapped in a List implementation. Changes to the sub
+ * list have to cause changes in the main list. This is a problem, since this class is to be
+ * used in a multi-threaded environment. The sub list could work on a copy as the iterators
+ * do, but all the functions which work on a given index could not be properly supported.
+ * Unfortunately, the List interface documentation states that all optional methods implemented
+ * by the list have to be implemented in the sub list. That would mean to do without all those
+ * critical methods, although they might work well in the "main list" (as opposed to sub list).

+     *  conversion. This implementation presumes that
+     *  the values are stored in member variables of the furthest inheriting class. For example,
+     *  class A inherits this class then members of class A
+     *  can hold property values. If there is a class B which inherits A then only members of B can hold
+     *  property values. The variables must be public. A property must have been registered (e.g. by
+     *  {@link #registerProperty(Property, Object)} in order for this method to work. The identifier argument (type Object)
+     *  used in the registerProperty methods must
+     *  be a String, which is, the name of the member variable that holds the property value.
+     *  If one opts to store values differently then one may override
+     *  this method, as well as {@link #setPropertyValueNoBroadcast setPropertyValueNoBroadcast} and
+     *  {@link #getPropertyValue(Property) getPropertyValue(Property)}.
+     *  This method is always called as a result of a call to one of the setter methods, such as
+     *  {@link #setPropertyValue(String,Object) XPropertySet.setPropertyValue},
+     *  {@link #setFastPropertyValue XFastPropertySet.setFastPropertyValue}
+     *  and {@link #setPropertyValues XMultiPropertySet.setPropertyValues}.
+     *  If this method fails, that is, it returns false or throws an exception, then no listeners are notified and the
+     *  property value, that was intended to be changed, remains untouched.
+     *
+     *  This method does not have to deal with property attributes, such as
+     *  PropertyAttribute.READONLY or PropertyAttribute.MAYBEVOID. The processing of these attributes occurs
+     *  in the calling methods.
+     *
+     *  Only if this method returns successfully further processing, such
+     *  as listener notification and finally the modification of the property's value, will occur.
+     *
+     *  The actual modification of a property's value is done by {@link #setPropertyValueNoBroadcast setPropertyValueNoBroadcast}
+     *  which is called subsequent to convertPropertyValue.
+     *<p>
+     *  This method converts values by help of the com.sun.star.uno.AnyConverter which only does a few widening
+     *  conversions on integer types and floating point types. For example, there is the property PropA with a Type equivalent
+     *  to int.class and the
+     *  value of the property is to be stored in a member variable of type int with name intProp. Then setPropertyValue is
+     *  called:
+     *  <pre>
+     *  set.setPropertyValue( "PropA", Byte.valueOf( (byte)111));
+     *  </pre>
+     *  At some point setPropertyValue will call convertPropertyValue and pass in the Byte object. Since we allow
+     *  that Byte values can be used with the property and know that the value is to be stored in intProp (type int)
+     *  we convert the Byte object into an Integer object which is then returned in the out-parameter <em>newVal</em>. This
+     *  conversion is actually performed by the AnyConverter. Later
+     *  the setPropertyValueNoBroadcast is called with that Integer object and the int value can be easily extracted
+     *  from the object and be assigned to the member intProp.
+     *  <p>
+     *  The method handles Any arguments the same as Object arguments. That is, the <em>setVal</em> argument can
+     *  be a java.lang.Boolean or a com.sun.star.uno.Any containing a java.lang.Boolean. Likewise, a member
+     *  containing a property value can be a com.sun.star.uno.Any or a java.lang.Object.
+     *  Then, no conversion is necessary, since they can hold all possible values. However, if
+     *  the member is an Object and <em>setVal</em> is an Any then the object contained in the any is assigned to
+     *  the member. The extra type information which exists as Type object in the Any will get lost. If this is not
+     *  intended then use an Any variable rather than an Object.
+     *
+     *  If a member is an Object or Any and the argument <em>setVal</em> is an Object, other than String or array,
+     *  then it is presumed to be a UNO object and queried for XInterface. If successful, the out-param <em>newVal</em>
+     *  returns the XInterface.
+     *
+     *  If a member is a UNO interface, then <em>setVal</em> is queried for this interface and the result is returned.
+     *  If <em>setVal</em> is null then <em>newVal</em> will be null too after return.
+     *  <p>
+     *  If a property value is stored using a primitive type the out-parameters
+     *  <em>curVal</em> and <em>newVal</em> contain the respective wrapper class (e.g.java.lang.Byte, etc.).
+     *  curVal is used in calls to the XVetoableChangeListener and XPropertyChangeListener.
+     *
+     * @param property - in-param property for which the data is to be converted.
+     * @param newVal - out-param which contains the converted value on return.
+     * @param curVal - out-param the current value of the property. It is used in calls to the
+     *                   XVetoableChangeListener and XPropertyChangeListener.
+     *  @param setVal - in-param. The value that is to be converted so that it matches Property and the internally used
+     *  dataformat for that property.
