Method Summary

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.
java.util.Vector	getDirectories(java.lang.String args) Returns all filepaths that follow a certain pattern.
java.util.Vector	reverse(java.util.Vector v) Reverses the elementorder in a vector.
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).
java.util.Vector	sortDirectories(java.util.Vector directories, java.lang.String comparefield) Sort a Vector containing file pathnames using a comparefield argument.

Method Detail

getDirectories

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

Returns all filepaths that follow a certain pattern.

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).
