Method Detail

execute

public static void execute(java.util.Collection collection,
                           Aggregate.Value value)

Merely executes the get call for each object in the collection.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

sum

public static float sum(java.util.Collection collection,
                        Aggregate.Value value)

Sums the characteristic over the included objects.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

Returns:

the sum.

average

public static float average(java.util.Collection collection,
                            Aggregate.Value value)

Averages the characteristic over the included objects.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

Returns:

the average (if it exists, if not, return 0).

minimum

public static float minimum(java.util.Collection collection,
                            Aggregate.Value value)

Finds the minimum of the characteristic over the included objects.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

Returns:

the minimum.

maximum

public static float maximum(java.util.Collection collection,
                            Aggregate.Value value)

Finds the maximum of the characteristic over the included objects.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

Returns:

the maximum.

maximumObject

public static java.lang.Object maximumObject(java.util.Collection collection,
                                             Aggregate.Value value)

Finds object with the maximum of the characteristic over the included objects.

Parameters:

value - the value interface to get the data.

collection - the collection to iterate over.

Returns:

the object with the maximum.
