Method Details

packValues

public static <T extends Enum<T> & VulkanEnumBitmaskType>
int packValues(Iterable<T> values)

Bitwise OR the integer values of all the given constants.

Type Parameters:

T - The precise type of enum

Parameters:

values - The values

Returns:

The integer-packed values

unpackValues

public static <T extends Enum<T> & VulkanEnumBitmaskType>
EnumSet<T> unpackValues(Class<T> enumClass,
 Supplier<T[]> enumValues,
 int flags)

Unpack flag values from a given integer.

Type Parameters:

T - The precise type of enum

Parameters:

enumClass - The enum class

enumValues - A function that returns the result of the enum's values() method.

flags - The flags value

Returns:

The integer-packed values

map

public static <T extends Enum<T> & VulkanEnumIntegerType>
Map<Integer,T> map(T[] values)

Produce an efficient map of integers to enum constants.

Type Parameters:

T - The precise type of enum

Parameters:

values - The list of enum values

Returns:

The resulting map
