|
||||
* An object describing the structure of metadata documents returned
|
||||
* from <code>IIOMetadata.getAsTree</code> and passed to
|
||||
* <code>IIOMetadata.setFromTree</code> and <code>mergeTree</code>.
|
||||
* Document structures are described by a set of constraints on the
|
||||
* type and number of child elements that may belong to a given parent
|
||||
* element type, the names, types, and values of attributes that may
|
||||
* belong to an element, and the type and values of
|
||||
* <code>Object</code> reference that may be stored at a node.
|
||||
*
|
||||
* <p> N.B: classes that implement this interface should contain a
|
||||
* method declared as <code>public static getInstance()</code> which
|
||||
* returns an instance of the class. Commonly, an implementation will
|
||||
* construct only a single instance and cache it for future
|
||||
* invocations of <code>getInstance</code>.
|
||||
*
|
||||
* <p> The structures that may be described by this class are a subset
|
||||
* of those expressible using XML document type definitions (DTDs),
|
||||
* with the addition of some basic information on the datatypes of
|
||||
* attributes and the ability to store an <code>Object</code>
|
||||
* reference within a node. In the future, XML Schemas could be used
|
||||
* to represent these structures, and many others.
|
||||
*
|
||||
* <p> The differences between
|
||||
* <code>IIOMetadataFormat</code>-described structures and DTDs are as
|
||||
* follows:
|
||||
*
|
||||
* <ul>
|
||||
* <li> Elements may not contain text or mix text with embedded
|
||||
* tags.
|
||||
*
|
||||
* <li> The children of an element must conform to one of a few simple
|
||||
* patterns, described in the documentation for the
|
||||
* <code>CHILD_*</code> constants;
|
||||
*
|
||||
* <li> The in-memory representation of an elements may contain a
|
||||
* reference to an <code>Object</code>. There is no provision for
|
||||
* representing such objects textually.
|
||||
* </ul>
