- Method Detail
  - getInstance
```
public static EmptyNamespaceDeclarationList getInstance()
```
    Get the singular instance of this class
    
    Returns:
    
    the singular instance of this class
  - getNamespaceCode
```
public int getNamespaceCode(int index)
```
    Get the n'th declaration in the list in the form of a namespace code. Namespace codes can be translated into a prefix and URI by means of methods in the NamePool
    
    Specified by:
    
    getNamespaceCode in interface NamespaceDeclarations
    
    Parameters:
    
    index - the index identifying which declaration is required.
    
    Returns:
    
    the namespace code. This is an integer whose upper half indicates the prefix (0 represents the default namespace), and whose lower half indicates the URI (0 represents an undeclaration).
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if the index is out of range.

    NamePool.getPrefixFromNamespaceCode(int), NamePool.getURIFromNamespaceCode(int)
  - getNamespaceCodes
```
public int[] getNamespaceCodes(int[] buffer)
```
    Get all the namespace codes, as an array.
    
    Specified by:
    
    getNamespaceCodes in interface NamespaceDeclarations
    
    Parameters:
    
    buffer - a sacrificial array that the method is free to use to contain the result. May be null.
    
    Returns:
    
    an integer array containing namespace codes. The array may be filled completely with namespace codes, or it may be incompletely filled, in which case a -1 integer acts as a terminator.
  - getNumberOfNamespaces
```
public int getNumberOfNamespaces()
```
    Get the number of declarations (and undeclarations) in this list.
    
    Specified by:
    
    getNumberOfNamespaces in interface NamespaceDeclarations
  - getPrefix
```
public java.lang.String getPrefix(int index)
```
    Get the prefix of the n'th declaration (or undeclaration) in the list, counting from zero.
    
    Specified by:
    
    getPrefix in interface NamespaceDeclarations
    
    Parameters:
    
    index - the index identifying which declaration is required.
    
    Returns:
    
    the namespace prefix. For a declaration or undeclaration of the default namespace, this is the zero-length string.
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if the index is out of range.
  - getURI
```
public java.lang.String getURI(int index)
```
    Get the namespace URI of the n'th declaration (or undeclaration) in the list, counting from zero.
    
    Specified by:
    
    getURI in interface NamespaceDeclarations
    
    Parameters:
    
    index - the index identifying which declaration is required.
    
    Returns:
    
    the namespace URI. For a namespace undeclaration, this is the zero-length string.
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if the index is out of range.
