/** provides a default <type>XEnumerableMap</type> implementation

    <p>For the keys put into the map using <member>XMap::put</member> or <member>createImmutable</member>,
    the following rules apply:
    <a name="keyrules"></a>
    <ul><li>A <VOID/> key is not allowed.</li>
        <li>If the key type is <code>BOOLEAN</code>, <code>CHAR</code>, <code>FLOAT</code>, <code>DOUBLE</code>,
            <code>STRING</code>, <code>TYPE</code>, or <code>UNSIGNED HYPER</code>, then only keys of exactly this
            type are accepted.</li>
        <li>If the key type is <code>DOUBLE</code> or <code>FLOAT</code>, then <code>Double.NaN</code> respectively
            <code>Float.NaN</code> is not accepted as key.</li>
        <li>If the key type's class is <member scope="com::sun::star::uno">TypeClass::ENUM</member>, then only keys
            of exactly this type are accepted.</li>
        <li>If the key type is any of <code>BYTE</code>, <code>SHORT</code>, <code>UNSIGNED SHORT</code>,
            <code>LONG</code>, <code>UNSIGNED LONG</code>, or <code>HYPER</code>, then all keys which can losslessly
            be converted to this type (possibly using widening conversions) are accepted.</li>
        <li>If the key type is an interface type, then all key values denoting objects which can be queried for
            the given interface are accepted.</li>
        <li>All other key types are rejected.</li>
    </ul></p>

    <p>For the values put into the map using <member>XMap::put</member> or <member>createImmutable</member>,
    the following rules apply:
    <a name="valuerules"></a>
    <ul><li>The <VOID/> value will be accepted to be put into the map.</p>
        <li>If the value type's class is <member scope="com::sun::star::uno">TypeClass::ANY</member>, any value
            will be accepted.</li>
        <li>If the value type is an interface type, then all values denoting objects which can be queried for
            the given interface are accepted.</li>
        <li>If the value type's class is <member scope="com::sun::star::uno">TypeClass::EXCEPTION</member>
            or <member scope="com::sun::star::uno">TypeClass::STRUCT</member>, then values whose type equals the
            value type, or is a sub class of the value type, are accepted.</li>
        <li>For all other value types, only values whose type matches exactly are accepted.</li>
        <li>If the value type is <code>DOUBLE</code> or <code>FLOAT</code>, then <code>Double.NaN</code> respectively
            <code>Float.NaN</code> is not accepted.</li>
    </ul></p>

    <p>The factory methods of the <code>XEnumerableMap</code> interface support both <em>isolated</em>
    and <em>non-isolated</em> enumerators. The latter one will be automatically disposed when the map changes
    after enumerator creation, so every attempt to use them will result in a
    <type scope="com::sun::star::lang">DisposedException</type> being thrown.</p>
