Method Detail

getResourcesInResourcesTreeByExtension

public static List<String> getResourcesInResourcesTreeByExtension(ResourcesTree tree,
                                                  String extension,
                                                  int depth)

Get the list of resources in the given ResoucesTree for a given extension.

Parameters:

tree -

extension - The extension.

depth - The depth of the recursive search. Negative number means all the way, zero means right in the resouce directory.

Returns:

getAllResourcesInResourcesTree

public static List<String> getAllResourcesInResourcesTree(ResourcesTree tree)

Get a list of all the resources in a given ResourcesTree.

Parameters:

tree - The ResourcesTree

Returns:

The List containing the name of all the resources.

getMergedPropertyFile

public static Properties getMergedPropertyFile(ResourcesTree tree,
                               String fileName)

Get a merged version of a given property file from the given ResourcesTree. The resource directories are scanned from the bottom up. Every time a property file for the given name is found, its properties are loaded using the load method on the Properties object. So all the properties are merged.

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)

Get a merged version of a given property file from the given ResourcesTree. The resource directories are scanned from the bottom up. Every time a property file for the given name is found, its properties are loaded using the load method on the Properties object. So all the properties are merged.

Parameters:

tree - The ResourcesTree in which property files are searched.

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

useSystem - If true the System Properties will be the parent of the returned Properties object.

Returns:

The Properties object with the merged properties.

getMergedProperties

public static Properties getMergedProperties(ResourcesTree tree,
                             String[] properties,
                             boolean useSystem,
                             ResourcesTreeProperties parentProps)
