Uses of ASTNode in edu.jmu.decaf

Subclasses of ASTNode in edu.jmu.decaf

Modifier and Type	Class and Description
class	ASTAssignment Decaf assignment statement.
class	ASTBinaryExpr Decaf binary operation with an operation tag and two child sub-expressions.
class	ASTBlock Lexical scope in a Decaf program; e.g., a function body or a while-loop body.
