org.qdl_lang.expressions.ExpressionNode

Packages that use ExpressionNode

Package	Description
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.
