Method Detail

getValueType

protected Class<V> getValueType()

getBuiltin

public Datatype.Builtin getBuiltin()

Specified by:

getBuiltin in interface Datatype<V>

Returns:

The built-in UPnP standardized type this datatype is mapped to or null if this is a custom datatype.

setBuiltin

public void setBuiltin(Datatype.Builtin builtin)

getString

public String getString(V value)
                 throws InvalidValueException

Description copied from interface: Datatype

Transforms a value supported by this datatype into a string representation.

This method calls Datatype.isValid(Object) before converting the value, it throws an exception if validation fails.

Specified by:

getString in interface Datatype<V>

Parameters:

value - The value to transform.

Returns:

The transformed value as a string, or an empty string when the value is null, never returns null.

Throws:

InvalidValueException

isValid

public boolean isValid(V value)

Specified by:

isValid in interface Datatype<V>

Parameters:

value - The value to validate or null.

Returns:

Returns true if the value was null, validation result otherwise.

toString

public String toString()

Overrides:

toString in class Object

getDisplayString

public String getDisplayString()

Specified by:

getDisplayString in interface Datatype<V>

Returns:

Metadata about this datatype, a nice string for display that describes this datatype (e.g. concrete class name).
