override bool Deveel.Data.Types.NumericType.CanCastTo ( SqlType destType )

inlinevirtual

Verifies if this type can cast any value to the given SqlType.

Parameters

destType The other type, destination of the cast, to verify.

By default, this method returns false, because cast process must be specified per type: when overriding the method CastTo, pay attention to also override this method accordingly.

Returns

CastTo

override DataObject Deveel.Data.Types.NumericType.CastTo	(	DataObject	value,
		SqlType	destType
	)

inlinevirtual

Converts the given object value to a SqlType specified.

Parameters

value	The value to convert.
destType	The destination type of the conversion.

If the given destType destination type is equivalent to this type, it will return the value provided, otherwise it will throw an exception by default.

Casting values to specific types is specific to each data-type: override this method to support type-specific conversions.

When overriding this method, CanCastTo should be overridden accordingly to indicate the type supports casting.

Returns: Returns an instance of DataObject that is the result of the conversion from this data-type to the other type given.

inlinevirtual

Verifies if a given SqlType is comparable to this data-type.

Parameters

type	The other data-type to verify the compatibility.

It is not required two SqlType to be identical to be compared: when overridden by a derived class, this methods verifies the properties of the argument type, to see if values handled by the types can be compared.

By default, this method compares the values returned by TypeCode to see if they are identical.

Returns: Returns true if the values handled by this data-type can be compared to ones handled by the given type , or false otherwise.

override SqlType Deveel.Data.Types.NumericType.Wider ( SqlType otherType )

inlinevirtual

Gets the one data-type between this and the other one given that handles the wider range of values.

Parameters

otherType The other type to verify.

This is very important for operations and functions, when operating on objects with comparable but different data-types, to ensure the result of the operation will be capable to handle the final value.

By default, this method returns this instance, as it is not able to dynamically define the wider type.

Returns: Returns this type if it handles a wider range of values or otherType other type given otherwise.
