convertNumber in class PrimitiveType<Short>

downCast

protected Short downCast(long value)

Specified by:

downCast in class IntegralType<Short>

validate

public Short validate(Object obj)

Description copied from class: FieldType

Verify the given object is a valid instance of this FieldType's Java type and cast it to that type.

Note that this method must throw IllegalArgumentException, not ClassCastException or NullPointerException, if obj does not have the correct type, or is an illegal null value.

This method is allowed to perform widening conversions of the object that lose no information, e.g., from Integer to Long.

The implementation in FieldType simply casts the value using this instance's raw Java type. Subclasses should override this method to implement any other restrictions, e.g., disallowing null values.

Overrides:

validate in class PrimitiveType<Short>

Parameters:

obj - object to validate

Returns:

obj cast to this field's type
