Method Detail

marshall

public String marshall(Object value)

Marshalls the given value into FEEL code that can be executed to reconstruct the value. For instance, here are some examples of the marshalling process:

* number 10 marshalls as: 10 * string foo marshalls as: "foo" * duration P1D marshalls as: duration( "P1D" ) * context { x : 10, y : foo } marshalls as: { x : 10, y : "foo" }

Specified by:

marshall in interface org.kie.dmn.feel.marshaller.FEELMarshaller<String>

Parameters:

value - the FEEL value to be marshalled

Returns:

a string representing the FEEL code that needs to be executed to reconstruct the value

unmarshall

public Object unmarshall(org.kie.dmn.feel.lang.Type feelType,
                         String value)

Unmarshalls the string into a FEEL value by executing it.

Specified by:

unmarshall in interface org.kie.dmn.feel.marshaller.FEELMarshaller<String>

Parameters:

feelType - this parameter is ignored by this marshaller and can be set to null

value - the FEEL code to execute for unmarshalling

Returns:

the value resulting from executing the code
