Method Detail
-
getNumberOfNamespaces
public int getNumberOfNamespaces()
Get the number of declarations (and undeclarations) in this list.- Specified by:
getNumberOfNamespaces
in interfaceNamespaceDeclarations
-
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 interfaceNamespaceDeclarations
- 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 interfaceNamespaceDeclarations
- 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.
-
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 interfaceNamespaceDeclarations
- 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.- See Also:
NamePool.getPrefixFromNamespaceCode(int)
,NamePool.getURIFromNamespaceCode(int)
-
getNamespaceCodes
public int[] getNamespaceCodes(int[] buffer)
Get all the namespace codes, as an array.- Specified by:
getNamespaceCodes
in interfaceNamespaceDeclarations
- 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.
