accept

public boolean accept(java.nio.file.Path basePath,
                      java.nio.file.Path relativePath,
                      java.nio.file.attribute.BasicFileAttributes attrs)

Description copied from interface: PathCondition

Returns true if the specified candidate path should be deleted, false otherwise.

Specified by:

accept in interface PathCondition

Parameters:

basePath - the directory from where to start scanning for deletion candidate files

relativePath - the candidate for deletion. This path is relative to the baseDir.

attrs - attributes of the candidate path

Returns:

whether the candidate path should be deleted

beforeFileTreeWalk

public void beforeFileTreeWalk()

Description copied from interface: PathCondition

Invoked before a new file tree walk is started. Stateful PathConditions can reset their state when this method is called.

Specified by:

beforeFileTreeWalk in interface PathCondition

createFileSizeCondition

@PluginFactory
public static IfAccumulatedFileSize createFileSizeCondition(@PluginAttribute(value="exceeds")
                                                                           java.lang.String size,

Create an IfAccumulatedFileSize condition.

Parameters:

threshold - The threshold accumulated file size from which files will be deleted.

Returns:

An IfAccumulatedFileSize condition.
