Method Detail

arrayOf

public static boolean[] arrayOf(boolean... values)

Generates a boolean[] from comma-separated values.

Parameters:

values - Comma-separated boolean values

Returns:

boolean[]

Since:

0.3.0

asObjectArray

public static Boolean[] asObjectArray(boolean[] array)

Converts from boolean[] to Boolean[].

Parameters:

array - boolean[]

Returns:

Equivalent Boolean[]

Since:

0.2.0

asPrimitiveArray

public static boolean[] asPrimitiveArray(Boolean[] array)

Converts from Boolean[] to boolean[].

Parameters:

array - Boolean[]

Returns:

Equivalent boolean[]

Since:

0.2.0

constantMap

public static <A> Map<A,Boolean> constantMap(Set<A> identifiers,
                             boolean value)

Returns a map filled with a given value.

Type Parameters:

A - Key type

Parameters:

identifiers - Set of map keys

value - Value for all elements

Returns:

A map with the given value in each entry

Since:

0.3.0

convertArray2Map

public static <A extends Number> Map<A,Boolean> convertArray2Map(Set<A> identifiers,
                                                 boolean[] array)

Returns a map containing the association of each identifier with its corresponding value within the array (in linear order). First element in the array will be associated to the first identifier in the set (in iteration order), second element in the array to the second element in the set, and so on.

Type Parameters:

A - Key type

Parameters:

identifiers - Set of identifier in ascending iterator order (duplicated and null values are not allowed)

array - Input array

Returns:

Map

Since:

0.3.0

convertTable2Map

public static <A extends Number,B extends Number> Map<Pair<A,B>,Boolean> convertTable2Map(Set<A> rowIdentifiers,
                                                                          Set<B> columnIdentifiers,
                                                                          boolean[][] table)

Returns a map containing the association of each identifier pair with its corresponding value within the table (in linear order). First element in the table will be associated to the first identifier pair (in iteration order), second element in the table to the second identifier pair, and so on.

Type Parameters:

A - Row key type

B - Column key type

Parameters:

rowIdentifiers - Set of row identifiers in ascending iterator order (null values are not allowed)

columnIdentifiers - Set of column identifiers in ascending iterator order (duplicated and null values are not allowed)

table - Input table

Returns:

Map

Since:

0.3.0

find

public static int[] find(boolean[] array,
         boolean value,
         Constants.SearchType searchType)

Returns the position(s) where a given value can be found into an array.

Parameters:

array - Input array

value - Value to be searched for

searchType - Indicates whether the first, the last, or all occurrences are returned

Returns:

Position(s) in which the given value can be found

Since:

0.2.0

select

public static boolean[] select(boolean[] array,
               int[] indexes)

Returns a set of selected elements from an input array. It is not backed in the input array, thus changes in this array are not reflected in the input array.

Parameters:

array - Input array

indexes - Position of elements to be selected.

Returns:

Set of elements in the order given by indexes

Since:

0.2.0

toArray

public static boolean[] toArray(Collection<Boolean> list)

Converts a collection (List, Set...) of Boolean objects to a boolean[].

Parameters:

list - Input list

Returns:

boolean[]

Since:

0.2.0

toList

public static List<Boolean> toList(boolean[] array)

Converts from a boolean[] to a list.

Parameters:

array - Input array

Returns:

A list of Boolean objects

Since:

0.2.0
