/**
|
||
|
|
* This interface represents an entity, either parsed or unparsed, in an XML
|
||
|
|
* document. Note that this models the entity itself not the entity
|
||
|
|
* declaration. <code>Entity</code> declaration modeling has been left for a
|
||
|
|
* later Level of the DOM specification.
|
||
|
|
* <p>The <code>nodeName</code> attribute that is inherited from
|
||
|
|
* <code>Node</code> contains the name of the entity.
|
||
|
|
* <p>An XML processor may choose to completely expand entities before the
|
||
|
|
* structure model is passed to the DOM; in this case there will be no
|
||
|
|
* <code>EntityReference</code> nodes in the document tree.
|
||
|
|
* <p>XML does not mandate that a non-validating XML processor read and
|
||
|
|
* process entity declarations made in the external subset or declared in
|
||
|
|
* external parameter entities. This means that parsed entities declared in
|
||
|
|
* the external subset need not be expanded by some classes of applications,
|
||
|
|
* and that the replacement value of the entity may not be available. When
|
||
|
|
* the replacement value is available, the corresponding <code>Entity</code>
|
||
|
|
* node's child list represents the structure of that replacement text.
|
||
|
|
* Otherwise, the child list is empty.
|
||
|
|
* <p>The DOM Level 2 does not support editing <code>Entity</code> nodes; if a
|
||
|
|
* user wants to make changes to the contents of an <code>Entity</code>,
|
||
|
|
* every related <code>EntityReference</code> node has to be replaced in the
|
||
|
|
* structure model by a clone of the <code>Entity</code>'s contents, and
|
||
|
|
* then the desired changes must be made to each of those clones instead.
|
||
|
|
* <code>Entity</code> nodes and all their descendants are readonly.
|
||
|
|
* <p>An <code>Entity</code> node does not have any parent.If the entity
|
||
|
|
* contains an unbound namespace prefix, the <code>namespaceURI</code> of
|
||
|
|
* the corresponding node in the <code>Entity</code> node subtree is
|
||
|
|
* <code>null</code>. The same is true for <code>EntityReference</code>
|
||
|
|
* nodes that refer to this entity, when they are created using the
|
||
|
|
* <code>createEntityReference</code> method of the <code>Document</code>
|
||
|
|
* interface. The DOM Level 2 does not support any mechanism to resolve
|
||
|
|
* namespace prefixes.
|
||
|
|
* <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
