public class Expression

extends UnnamedRuleComponent

An expression is a String containing one or more primary expression terms.

The validate() methods validate that the expression is syntactically and semantically correct for the context in which it is used.

The expression value is a string as the user sees it. The resolved value has aliases replaced with IDs in backquotes (e.g. `L}10`). The value and resolved value are synchronized (changing one changes the other). Most users never need to worry about the resolved value.

An expression may be designated as a constant. This affects the value options and makes string quotes optional on input.
