Method Detail
-
addNamespace
public void addNamespace(java.lang.String prefix, java.lang.String uri)
Adds the given namespace declaration to this Namespaces- Parameters:
prefix
- the namespace prefixuri
- the namespace URI to be associated with the given prefix
-
createNamespaces
public Namespaces createNamespaces()
Creates a new Namespaces instance with this Namespaces as the parent
-
getLocalNamespaces
public java.util.Enumeration getLocalNamespaces()
Returns an Enumeration of local namespace URIs for this Namespaces.- Returns:
- an Enumeration of local namespace URIs.
-
getNamespaceURI
public java.lang.String getNamespaceURI(java.lang.String prefix)
Returns the Namespace URI associated with the given prefix- Parameters:
prefix
- the namespace prefix to lookup- Returns:
- the namespace URI associated with the given prefix
-
getNamespacePrefix
public java.lang.String getNamespacePrefix(java.lang.String nsURI)
Returns the Namespace prefix associated with the given URI. If multiple namespace prefixes have been declared, then the first one found is returned. To obtain all prefixes see#getNamespacePrefixes
.- Parameters:
nsURI
- the namespace URI to lookup- Returns:
- the namespace prefix associated with the given URI
-
getLocalNamespacePrefixes
public java.util.Enumeration getLocalNamespacePrefixes()
Returns all namespace prefixes declared locally- Returns:
- an Enumeration of locally declared namespace prefixes
-
getNamespacePrefixes
public java.lang.String[] getNamespacePrefixes(java.lang.String nsURI)
Returns all namespace prefixes associated with the given URI, including those from parent scopes.- Parameters:
nsURI
- the namespace URI to lookup- Returns:
- the namespace prefixes associated with the given URI
-
getNamespacePrefixes
public java.lang.String[] getNamespacePrefixes(java.lang.String nsURI, boolean local)
Returns the Namespace prefixes associated with the given URI.- Parameters:
nsURI
- the namespace URI to lookuplocal
- a boolean that when true indicates only the local scope is searched.- Returns:
- the namespace prefixes associated with the given URI
-
getNonDefaultNamespacePrefix
public java.lang.String getNonDefaultNamespacePrefix(java.lang.String nsURI)
Returns the Namespace prefix associated with the given URI. Or null if no prefix has been declared. This method will ignore the default namespace. This is useful when dealing with attributes that do not use the default namespace.- Parameters:
nsURI
- the namespace URI to lookup- Returns:
- the namespace prefix associated with the given URI
-
getParent
public Namespaces getParent()
Returns the parent Namespaces for this Namespaces instance.- Returns:
- the parent Namespaces for this Namespaces instance.
-
removeNamespace
public boolean removeNamespace(java.lang.String prefix)
Removes the namespace declaration for the given prefix. This is a local action only, the namespace declaration will not be removed from any parent Namespaces object.- Parameters:
prefix
- the namespace prefix to remove the binding of- Returns:
- true if the namespace declaration was removed, otherwise false.
-
setParent
public void setParent(Namespaces namespaces)
Sets the parent Namespaces for this Namespaces instance.- Parameters:
namespaces
- the parent Namespaces
-
declareAsAttributes
public void declareAsAttributes(org.xml.sax.helpers.AttributeListImpl atts, boolean localOnly)
Declare the namespaces of this stack in as attributes.- Parameters:
atts
- the Attribute List to fill in.
