Descriptor

```
public interface Descriptor
```
The Descriptor interface defines a mechanism for inspecting a node of an XML based document.
The idea is to give a programmer the ability to inspect the various tags and attribute values without having to parse the tags. This is useful in that some XML based documents do post-parser processing that can then be handled appropriately by implementations of this interface.

- Method Detail
  - getAttributeList
```
String[] getAttributeList()
```
    Returns an array of attribute names for the current node.
    
    Returns:
    Array containing the names of all attributes associated with the node type for this descriptor. If there are no attributes for this descriptor, an empty array is returned.
  - getAttributeValue
```
String getAttributeValue(String attr)
```
    Returns the value of the named attribute.
    
    Returns:
    String containing the value of the specified attribute. If the named attribute is not valid for this descriptor, null is returned.
  - getChildren
```
Enumeration getChildren()
```
    Returns the Descriptors of the children of this node.
    
    Returns:
    Descriptors for the children of this Descriptor as an Enumeration. If there are no children, an empty enumeration is returned.
  - getDescriptor
```
Descriptor getDescriptor(String qualifiedName)
```
    Returns the Descriptor for another element contained within the same document.
    
    Returns:
    Descriptor for another element within the same document given a qualified name (i.e. - "structName1.structName2.dataElementName"). Returns null if there is no element with the specified name.
  - getName
```
String getName()
```
    Returns the simple name of the Descriptor as specified on the name= attribute of its associated tag.
    
    Returns:
    String containing the simple name of the Descriptor as specified on the name= attribute of its associated tag. If there is no name= attribute, null is returned.
  - getQualifiedName
```
String getQualifiedName()
```
    Returns the qualified name of the Descriptor. This qualified name is the simple name prefixed with the qualified name of this Descriptor's parent and separated with a period (".").
    
    Returns:
    String containing the qualified name of the Descriptor. If there is no qualified name, null is returned.
  - getTagName
```
String getTagName()
```
    Returns the tag name of the Descriptor.
    
    Returns:
    String containing the tag name of the element in the Descriptor.
  - hasChildren
```
boolean hasChildren()
```
    Returns true if this Descriptor has childen. Returns false if this Descriptor has no childen.
    
    Returns:
    Boolean indicating if the Descriptor has children.
