public static Properties getMergedPropertyFile(ResourcesTree tree,
                               String fileName)

Parameters:

tree - The ResourcesTree in which property files are searched.

fileName - The name of the property file to search for.

Returns:

The Properties object with the merged properties.

getMergedPropertyFile

public static Properties getMergedPropertyFile(ResourcesTree tree,
                               String fileName,
                               boolean useSystem)
