    Parameters:

- Method Detail
  - getPrefix
```
protected static String getPrefix(NodePointer pointer,
               String namespaceURI)
```
    Find the namespace prefix for the specified namespace URI and NodePointer.
    
    Parameters:
    pointer - location
    namespaceURI - to check
    
    Returns:
    prefix if found
    Since:
    
    JXPath 1.3
  - registerNamespace
```
public void registerNamespace(String prefix,
                     String namespaceURI)
```
    Registers a namespace prefix.
    
    Parameters:
    prefix - A namespace prefix
    namespaceURI - A URI for that prefix
  - setNamespaceContextPointer
```
public void setNamespaceContextPointer(NodePointer pointer)
```
    Register a namespace for the expression context.
    
    Parameters:
    pointer - the Pointer to set.
  - getNamespaceContextPointer
```
public Pointer getNamespaceContextPointer()
```
    Get the namespace context pointer.
    
    Returns:
    Pointer
  - getNamespaceURI
```
public String getNamespaceURI(String prefix)
```
    Given a prefix, returns a registered namespace URI. If the requested prefix was not defined explicitly using the registerNamespace method, JXPathContext will then check the context node to see if the prefix is defined there. See setNamespaceContextPointer.
    
    Parameters:
    prefix - The namespace prefix to look up
    
    Returns:
    namespace URI or null if the prefix is undefined.
  - getExternallyRegisteredNamespaceURI
```
protected String getExternallyRegisteredNamespaceURI(String prefix)
```
    Given a prefix, returns an externally registered namespace URI.
    
    Parameters:
    prefix - The namespace prefix to look up
    
    Returns:
    namespace URI or null if the prefix is undefined.
    Since:
    
    JXPath 1.3
  - getPrefix
```
public String getPrefix(String namespaceURI)
```
    Get the prefix associated with the specifed namespace URI.
    
    Parameters:
    namespaceURI - the ns URI to check.
    
    Returns:
    String prefix
  - getExternallyRegisteredPrefix
```
protected String getExternallyRegisteredPrefix(String namespaceURI)
```
    Get the nearest prefix found that matches an externally-registered namespace.
    
    Parameters:
    namespaceURI - the ns URI to check.
    
    Returns:
    String prefix if found.
    Since:
    
    JXPath 1.3
  - isSealed
```
public boolean isSealed()
```
    Learn whether this NamespaceResolver has been sealed.
    
    Returns:
    boolean
  - seal
```
public void seal()
```
    Seal this NamespaceResolver.
  - clone
```
public Object clone()
```
    Overrides:
    
    clone in class Object
