Class RowEntries

java.lang.Object

alma.acs.logging.table.RowEntries

public class RowEntries
extends java.lang.Object

The data structure containing all the rows of the table (in the model coordinate space). It encapsulate a list of keys.

For the user point of view, RowEntries contains the keys of the logs in the table: the keys in position i is the key of the log shown in the table in position i.

Implementation note.
Even if logically, the entry in position i contains the key of the log to show in the row i of the table, to improve performances, new keys are appended in the tail of the vector instead of being inserted in the head i.e. the key of the first log (in row 0) is is the last key of the vector (in position size-1). For this reason, get(int) convert from the passed index to the real position in the list.

See Also:

List.size()

add

public void add(java.lang.Integer key)

Add the passed key to the list of entries.

To improve performances, the key is appended at the end of the vector

Parameters:

key - The integer key to add to the list

get

public java.lang.Integer get(int row)

Return the key at the given row of the table.

For a deeper understanding of the algorithm, read the implementation note in RowEntries.

Parameters:

index - The index of the key to get

Returns:

The key at passed row of the table

clear

public void clear()

See Also:

List.clear()

indexOf

public int indexOf(java.lang.Integer key)

Return the position (i.e. the row in the table) that contains the passed key

For a deeper understanding of the algorithm, read the implementation note in RowEntries.

Parameters:

key - The key to look for in the table

Returns:

The position in the list of the passed key or -1 if the list does not contain the passed key
