Type Parameters:

S - the generic type for scaleMetrics

Parameters:

scaleMetrics - the scale metrics

Returns:

the factory constant corresponding to scaleMetrics

getGenericDecimalFactory

public static final GenericDecimalFactory<?> getGenericDecimalFactory(int scale)

Returns the GenericDecimalFactory based on a given scale.

Parameters:

scale - the scale value; must be in [0,18] both ends inclusive

Returns:

the generic factory corresponding to scale

Throws:

IllegalArgumentException - if scale is not in [0, 18]

getGenericDecimalFactory

public static final <S extends ScaleMetrics> GenericDecimalFactory<S> getGenericDecimalFactory(S scaleMetrics)
