Interface SourceExpression

public interface SourceExpression
An expression read out of source code, exposed without revealing the parse tree it came from.

This exists because reading a property does not always yield a value. A property may be set from a method call, a constant reference, or a string template, and the property panel has to render something for all of them. Callers previously received a JavaParser node and tested it with instanceof MethodCallExpr, which only works for one language.
