Method Detail

addPropNodes

public int addPropNodes()

Add to propNodes the PropNodes appropriate for this kind of cluster.

Overrides:

addPropNodes in class PropertyPack.Cluster

Returns:

the number of propnodes in the cluster

openFile

public InputStream openFile(java.lang.String relName)
                     throws IOException

Specified by:

openFile in class PropertyPack.Cluster

Parameters:

relName - location of the desired file within the cluster. Usually this method is called from createPropNode; in this case relName is a locale suffix and an extension. To open a sibling of the properties file, relName may be /../siblingname.ext.

Returns:

an InputStream for the file at relName in the cluster. The cluster's memberStem is prepended to the name.

The client MUST close the stream. Accordingly, an IOException may thrown. This is intended to encourage calling this method from within the parenthesized resouces clause of a try statement.

Throws:

IOException - if an error occurs.

toString

public java.lang.String toString()

Specified by:

toString in class PropertyPack.Cluster

Returns:

(Subclasses should return: classname ":" directory " : " memberStem.)
