Package net.sourceforge.plantuml.jasic

Interface Jasic.Value

All Superinterfaces:

Jasic.Expression

All Known Implementing Classes:

Jasic.NumberValue, Jasic.StringValue

Enclosing class:

Jasic

public static interface Jasic.Value
extends Jasic.Expression

This is the base interface for a value. Values are the data that the interpreter processes. They are what gets stored in variables, printed, and operated on. There is an implementation of this interface for each of the different primitive types (really just double and string) that Jasic supports. Wrapping them in a single Value interface lets Jasic be dynamically-typed and convert between different representations as needed. Note that Value extends Expression. This is a bit of a hack, but it lets us use values (which are typically only ever seen by the interpreter and not the parser) as both runtime values, and as object representing literals in code.
