public class SortedTable

extends java.util.TreeMap

This class is used to hold the table entries in a Sorted fashion. This would be useful in the case of a JMX Agent where the indices would be handled as an Object[]. This method overrides certain methods from TreeMap and those methods are declares as synchronized.

Constructor Detail

SortedTable

public SortedTable()

Constructor which creates a new instance of this object.

Method Detail

put

public java.lang.Object put(java.lang.Object[] keys,
                            java.lang.Object value)

Used to put the entry object identified by the keys.

Returns:

Any old value identified by the same key or null if not present previously.

get

public java.lang.Object get(java.lang.Object[] keys)

Retrieves the Entry object identified by the keys.

get

public java.lang.Object get(int index)

Retrieves the Entry object identified by the index. It is recommended not to invoke this method within a loop as this may affect the performance. Instead the toArray() can be used when required in a loop.

Parameters:

index - The index starting from zero.

getNext

public java.lang.Object getNext(java.lang.Object[] keys)

Returns the next element to the specified keys.

Returns:

null if no matching entry found.

containsKey

public boolean containsKey(java.lang.Object[] keys)

Checks whether this table contains the specified keys.

Returns:

true if present, false otherwise.

remove

public java.lang.Object remove(java.lang.Object[] keys)

Removes the entry object identified by the keys, if present.

Returns:

The value object identified by the key.

size

public int size()

Returns the number of entries in the table.

Overrides:

size in class java.util.TreeMap

firstEntry

public java.lang.Object firstEntry()

Returns the first Entry from the table.

getEntries

public java.util.List getEntries(int startIndex,
                                 int endIndex)

Returns a List of table indices (A List of Object[]'s)

toKeysArray

public java.lang.Object[] toKeysArray()

Used to get the keys contained in this Map as an Object[]. The values would be in a Sorted fashion.

Returns:

An Object[] of the keys contained in this Map.

toArray

public java.lang.Object[] toArray()

Used to get the values contained in this Map as an Object[]. The values would be in a Sorted fashion.

Returns:

An Object[] of the values contained in this Map.

toArray

public java.lang.Object[] toArray(java.lang.Object[] o)

Returns an array containing all of the values in this Map whose runtime type is that of the specified array.

Returns:

An Object[] of the values contained in this Map.
