Field Detail

ATOMIC_LONG

public static final NumberTypeImpl<AtomicLong> ATOMIC_LONG

The NumberTypeImpl for AtomicLong.

ATOMIC_INTEGER

public static final NumberTypeImpl<AtomicInteger> ATOMIC_INTEGER

The NumberTypeImpl for AtomicInteger.

instance

private static MathUtil instance

Constructor Detail

MathUtilImpl

public MathUtilImpl()

The constructor.

Method Detail

getInstance

public static MathUtil getInstance()

This method gets the singleton instance of MathUtil.
ATTENTION:
Please read Cdi.GET_INSTANCE before using.

Returns:

the singleton instance.

getNumberType

public NumberType<? extends Number> getNumberType(Class<?> numericType)

Description copied from interface: MathUtilLimited

This method gets the NumberType for the given numericType.

Specified by:

getNumberType in interface MathUtilLimited

Overrides:

getNumberType in class MathUtilLimitedImpl

Parameters:

numericType - is the class reflecting a Number. It may be primitive (such as int.class). The signature is NOT bound to Number to make it easy for the caller (e.g. Number.class.isAssignableFrom(int.class) is false).

Returns:

the NumberType representing the given numericType or null if the given numericType is no Number or is NOT known (you may extend this MathUtilLimited in such case).
