Method Detail

empty

public static speiger.src.collections.doubles.utils.DoubleLists.EmptyList empty()

Returns a Immutable EmptyList instance that is automatically casted.

Returns:

an empty list

unmodifiable

public static DoubleList unmodifiable(DoubleList l)

Returns a Immutable List instance based on the instance given.

Parameters:

l - that should be made immutable/unmodifiable

Returns:

a unmodifiable list wrapper. If the list is implementing RandomAccess that is also transferred. If the List already a unmodifiable wrapper then it just returns itself.

synchronize

public static DoubleList synchronize(DoubleList l)

Returns a synchronized List instance based on the instance given.

Parameters:

l - that should be synchronized

Returns:

a synchronized list wrapper. If the list is implementing RandomAccess or IDoubleArray that is also transferred. If the List already a synchronized wrapper then it just returns itself.

synchronize

public static DoubleList synchronize(DoubleList l,
                                     java.lang.Object mutex)

Returns a synchronized List instance based on the instance given.

Parameters:

l - that should be synchronized

mutex - is the controller of the synchronization block.

Returns:

a synchronized list wrapper. If the list is implementing RandomAccess or IDoubleArray that is also transferred. If the List already a synchronized wrapper then it just returns itself.

singleton

public static DoubleList singleton(double element)

Creates a Unmodifiable Singleton list

Parameters:

element - that should be used in the Singleton

Returns:

a singleton list that is unmodifiable

reverse

public static DoubleList reverse(DoubleList list)

Reverses the list

Parameters:

list - that should be reversed.

Returns:

the input list

shuffle

public static DoubleList shuffle(DoubleList list)

Shuffles the list

Parameters:

list - that should be Shuffled.

Returns:

the input list

shuffle

public static DoubleList shuffle(DoubleList list,
                                 java.util.Random random)

Shuffles the list

Parameters:

list - that should be Shuffled.

random - the random that should be used

Returns:

the input list
