Returns the entry that is either equal or less than this key.

Parameters:

key -

Returns:

getKeys

public long[] getKeys()

Copys the list contents into a new array.

Returns:

the list contents as array.

public long[] getKeys(long[] retval)

findKeyPosition

public int findKeyPosition(long coordinate,
                           boolean greater)

Returns:

removeAll

public void removeAll(long[] cutArray,
                      long cutSize)

Expects a sorted (ascending) list of cut-entries that should be removed. You will run into troubles if the list is not sorted.

Parameters:

cutArray -

offset

public void offset(long offset)
