Uses of Interface
org.qdl_lang.statements.ExpressionInterface

Packages that use ExpressionInterface

Package	Description
org.qdl_lang.evaluate	Evaluators evaluate the built-in functions for QDL as well as perform the usual algebraic operations.
org.qdl_lang.expressions	Expressions are objects that take zero or more arguments and return a result.
org.qdl_lang.functions	Function handling and processing.
org.qdl_lang.parsing	Classes that support parsing and the parser itself.
org.qdl_lang.statements	The two basic syntactic units of QDL are expressions (which return results) and statements which are the other control structures, such as conditionals, loops, etc.
org.qdl_lang.variables	Variables in QDL and classes that support them.

Subinterfaces of ExpressionInterface in org.qdl_lang.expressions

Modifier and Type	Interface	Description
