Interface MetaNode</H2>
<HR>
<DL>
<DT><PRE>public interface <B>MetaNode</B></DL>
</PRE>

<P>
The MetaNode contains meta data as standardized by OMA DM but extends it
 (without breaking the compatibility) to provide for better DMT data quality
 in an environment where many software components manipulate this data.
 <p>
 The interface has several types of functions to describe the nodes in the
 DMT. Some methods can be used to retrieve standard OMA DM metadata such as
 access type, cardinality, default, etc., others are for data extensions such
 as valid names and values. In some cases the standard behaviour has been
 extended, for example it is possible to provide several valid MIME types, or
 to differentiate between normal and automatic dynamic nodes.
 <p>
 Most methods in this interface receive no input, just return information
 about some aspect of the node. However, there are two methods that behave
 differently, <A HREF="../../info/dmtree/MetaNode.html#isValidName(java.lang.String)"><CODE>isValidName(java.lang.String)</CODE></A> and <A HREF="../../info/dmtree/MetaNode.html#isValidValue(info.dmtree.DmtData)"><CODE>isValidValue(info.dmtree.DmtData)</CODE></A>. These validation
 methods are given a potential node name or value (respectively), and can
 decide whether it is valid for the given node. Passing the validation methods
 is a necessary condition for a name or value to be used, but it is not
 necessarily sufficient: the plugin may carry out more thorough (more
 expensive) checks when the node is actually created or set.
 <p>
 If a <code>MetaNode</code> is available for a node, the DmtAdmin must use the
 information provided by it to filter out invalid requests on that node.
 However, not all methods on this interface are actually used for this
 purpose, as many of them (e.g. <A HREF="../../info/dmtree/MetaNode.html#getFormat()"><CODE>getFormat()</CODE></A> or <A HREF="../../info/dmtree/MetaNode.html#getValidNames()"><CODE>getValidNames()</CODE></A>)
 can be substituted with the validating methods. For example,
 <A HREF="../../info/dmtree/MetaNode.html#isValidValue(info.dmtree.DmtData)"><CODE>isValidValue(info.dmtree.DmtData)</CODE></A> can be expected to check the format, minimum, maximum,
 etc. of a given value, making it unnecessary for the DmtAdmin to call
 <A HREF="../../info/dmtree/MetaNode.html#getFormat()"><CODE>getFormat()</CODE></A>, <A HREF="../../info/dmtree/MetaNode.html#getMin()"><CODE>getMin()</CODE></A>, <A HREF="../../info/dmtree/MetaNode.html#getMax()"><CODE>getMax()</CODE></A> etc. separately.
 It is indicated in the description of each method if the DmtAdmin does not
 enforce the constraints defined by it - such methods are only for external
 use, for example in user interfaces.
 <p>
 Most of the methods of this class return <code>null</code> if a certain piece
 of meta information is not defined for the node or providing this information
 is not supported. Methods of this class do not throw exceptions.

<DD>Get the node's format, expressed in terms of type constants defined in

 the format constants are OR-ed. Interior nodes must have

 for leaf nodes. If no meta-data is provided for a node, all applicable
 formats are considered valid (with the above constraints regarding
 interior and leaf nodes).
 <p>
 Note that the 'format' term is a legacy from OMA DM, it is more customary
 to think of this as 'type'.
 <p>
 The formats returned by this method are not checked by DmtAdmin, they

<DL>
<DD>Get the format names for any raw formats supported by the node.  This
 method is only meaningful if the list of supported formats returned by

 format(s) are actually supported.  If the node cannot contain data in one
 of the raw types, this method must return <code>null</code>.
 <p>
 The format names returned by this method are not checked by DmtAdmin,

<DL>
<DD>Checks whether the given value is valid for this node. This method can be
 used to ensure that the value has the correct format and range, that it
 is well formed, etc. This method should be consistent with the
 constraints defined by the <A HREF="../../info/dmtree/MetaNode.html#getFormat()"><CODE>getFormat()</CODE></A>, <A HREF="../../info/dmtree/MetaNode.html#getValidValues()"><CODE>getValidValues()</CODE></A>,

 Admin only calls this method for value validation.
 <p>
 This method may return <code>true</code> even if not all aspects of the
 value have been checked, expensive operations (for example those that
 require external resources) need not be performed here. The actual value
 setting method may still indicate that the value is invalid.

<DD>Return an array of Strings if valid names are defined for the node, or
 <code>null</code> if no valid name list is defined or if this piece of
 meta info is not supported. If no meta-data is provided for a node, all
 names are considered valid.

<DL>
<DD>Checks whether the given name is a valid name for this node. This method
 can be used for example to ensure that the node name is always one of a
 predefined set of valid names, or that it matches a specific pattern.
 This method should be consistent with the values returned by
 <A HREF="../../info/dmtree/MetaNode.html#getValidNames()"><CODE>getValidNames()</CODE></A> (if any), the DmtAdmin only calls this method for
 name validation.
 <p>
 This method may return <code>true</code> even if not all aspects of the
 name have been checked, expensive operations (for example those that
 require external resources) need not be performed here. The actual node
 creation may still indicate that the node name is invalid.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>name</CODE> - the node name to check for validity
