All Implemented Interfaces:

public class NSProperties
extends XProperties

In addition to the abilities of XProperties this allows for

• Basic but extremely useful namespace support. You may get/set properties using a namespace in addition to a property key. Be warned this is simple since it just gloms the namespace in front of the key, but it works quite well for most cases.

There is prefix resolution, if prefixes are found. For instance, this might be a properties file:

     xmlns\:fileStore=http://my.ns/fileStore#
     xmlns\:email=myproxy:ncsa,2011/1.1/email#
     fileStore\:dataPath=/tmp/data
     fileStore\:indexPath=/tmp/index
     email\:enabled=false
 

(The "\" on the left-hand side is colon escaping from the Java Properties class.) In which case you could retrieve values as getBoolean("email", "enabled") or getBoolean("myproxy:ncsa,2011/1.1/email#enabled")

You may add or remove prefixes by calling the appropriate addNSPrefix(String, String) method. These will be saved as part of the properties file.

Method Detail

getPrefixToNS

public HashMap<String,String> getPrefixToNS()

addNSPrefix

public void addNSPrefix(String ns,
                        String prefix)

removeNS

public void removeNS(String ns)

getNamespaces

public Collection<String> getNamespaces()

getPrefixes

public Collection<String> getPrefixes()

getNsToPrefix

protected HashMap<String,String> getNsToPrefix()

Support for namespace resolution.

Returns:

getBoolean

public boolean getBoolean(String ns,
                          String key)

resolveKey

protected String resolveKey(String ns,
                            String key)

Resolve a namespace to a single key. This is very simple. It appends the key to the namespace, checking if the XProperties.NAMESPACE_DELIMITER is needed. If there is no namespace provided, this just returns the key.

Parameters:

ns -

key -

Returns:

toPrefix

protected String toPrefix(String key)

Given a namespace, or a prefix, resolve to the actual namespace.

Parameters:

key -

Returns:

toNS

protected String toNS(String key)

Given a key with a prefix or a namespace, resolve it to the namepsace + key. If there is no key this is equivalent to just doing a lookup.

Parameters:

key -

Returns:

setBoolean

public void setBoolean(String ns,
                       String key,
