Interface Summary

Compilable	An interface of values that are compilable as Literals.
CompiledProc	Interface exported by Scheme procedures that are compiled to bytescodes.
Inlineable

Class Summary

ApplyExp	This class is used to represent "combination" or "application".
BeginExp	This class represents a sequence of Expressions.
BindingInitializer
BlockExp	Class used to implement a block that can be exited.
CatchClause	A "catch" clause of a "try-catch" form.
ChainLambdas	Sets up the firstChild/nextSibling links of each LambdaExp.
CheckedTarget	Same as StackTarget, but catch ClassCastException.
ClassExp
Compilation
ConditionalTarget	This is the Target of a boolean expression, in a conditional context.
Declaration	The static information associated with a local variable binding.
ErrorExp	Class used to mark an erroneous expression
ExitExp	Expression to exit a lexically surrounding block.
ExpFullWalker	An ExpWalker for doing a complete left-to-right tree walk.
Expression	Abstract class for syntactic forms that evaluate to a value.
ExpWalker
FindCapturedVars
FindTailCalls	Does setTailCall on ApplyExp's that are tail-calls.
FluidLetExp	Class used to implement "fluid-let" for Scheme and "let" for Emacs.
GenericProc	A collection of MethodProcs; one is chosen at apply time.
IfExp	This class represents a conditional.
IgnoreTarget
Initializer	A piece of code that needs to be added to .
Interpreter	Contains various language-dependent methods.
Keyword
LambdaExp	Class used to implement Scheme lambda expressions.
LetExp	Class used to implement "let" syntax (and variants) for Scheme.
Literal	A Literal contains compile-time information about a constant.
MethodProc	Similar to a CLOS method.
ModuleBody	Abstract class for the dummy top-level function of a module.
ModuleExp	Class used to implement Scheme top-level environments.
ModuleMethod	Call a specified method in in a ModuleBody.
ObjectExp
PrimProcedure	A primitive Procedure implemented by a plain Java method.
ProcInitializer
PushApply	Re-arranges ApplyExp where the function is a LetExp or BeginExp.
QuoteExp	An Expression that evaluates to a constant value.
ReferenceExp	This class represents a variable reference (an identifier).
ScopeExp	Abstract class for expressions that add local variable bindings.
SetApplyExp	Implements a function call in the LHS of an assignment.
SetExp	An Expression to set (bind) or define a new value to a named variable.
Special	A class of special one-of-a-kind builtin values.
StackTarget
Symbol	Utility class containing various routines to manipulate Scheme symbols.
SynchronizedExp
TailTarget
Target	This represents where a compiler can put the result of an expression.
ThisExp	Evaluates to the "this" implicit variable.
TryExp	This class represents try/catch/finally.
Undefined
