Method Detail

getDirectories

public java.util.Vector getDirectories(java.lang.String args)

Returns all filepaths that follow a certain pattern.

Parameters:

args - The requeststring to be used. This string consists of a directory, followed by an extension.

Returns:

a vector containing all filepaths requested.

sortDirectoriesOnModTime

public java.util.Vector sortDirectoriesOnModTime(java.util.Vector directories)

Sorts a Vector containing file pathnames on modification time.

Returns:

a new sorted Vector containing filepathnames.

sortDirectories

public java.util.Vector sortDirectories(java.util.Vector directories,
                                        java.lang.String comparefield)

Sort a Vector containing file pathnames using a comparefield argument. First creates XFile objs from vector. It then adds these objs to a SortedVector obj (sorted on comparefield)..

Returns:

a Vector with 2 items : filepath & moddate

createThreeItems

public java.util.Vector createThreeItems(java.util.Vector sorted,
                                         StringTagger tagger)

This method creates a vector with 3 items: ITEM1=fileentry, ITEM2=moddate, ITEM3=previewfilename if exists else fileentry.

reverse

public java.util.Vector reverse(java.util.Vector v)

Reverses the elementorder in a vector.

reverse

public java.util.Vector reverse(java.util.Vector v,
                                int items)

Reverses the elementorder in a vector, taking into consideration that the vector consists of sets of elements (items).
