Method Detail

sortByID

public static <KEYTYPE,DATATYPE,ITEMTYPE extends ITreeItemWithID<KEYTYPE,DATATYPE,ITEMTYPE>> void sortByID(@Nonnull
                                                                                           IBasicTree<DATATYPE,ITEMTYPE> aTree,
                                                                                           @Nonnull
                                                                                           Comparator<? super KEYTYPE> aKeyComparator)

Sort each level of the passed tree on the ID with the specified comparator.

Parameters:

aTree - The tree to be sorted.

aKeyComparator - The comparator to be used for sorting the tree item keys on each level.

sortByID

public static <KEYTYPE extends Comparable<? super KEYTYPE>,DATATYPE,ITEMTYPE extends ITreeItemWithID<KEYTYPE,DATATYPE,ITEMTYPE>> void sortByID(@Nonnull
                                                                                                                               IBasicTree<DATATYPE,ITEMTYPE> aTree)

Sort each level of the passed tree on the ID with the specified comparator. This method assumes that the IDs in the tree item implement the Comparable interface.

Parameters:

aTree - The tree to be sorted.

sortByValue

public static <KEYTYPE,DATATYPE,ITEMTYPE extends ITreeItemWithID<KEYTYPE,DATATYPE,ITEMTYPE>> void sortByValue(@Nonnull
                                                                                              IBasicTree<DATATYPE,ITEMTYPE> aTree,
                                                                                              @Nonnull
                                                                                              Comparator<? super DATATYPE> aValueComparator)

Sort each level of the passed tree on the value with the specified comparator.

Parameters:

aTree - The tree to be sorted.

aValueComparator - The comparator to be used for sorting the tree item keys on each level.

sortByValue

public static <KEYTYPE,DATATYPE extends Comparable<? super DATATYPE>,ITEMTYPE extends ITreeItemWithID<KEYTYPE,DATATYPE,ITEMTYPE>> void sortByValue(@Nonnull
                                                                                                                                   IBasicTree<DATATYPE,ITEMTYPE> aTree)

Sort each level of the passed tree on the value with the specified comparator. This method assumes that the values in the tree item implement the Comparable interface.

Parameters:

aTree - The tree to be sorted.
