Method Detail

mustCompile
protected boolean mustCompile()
- Specified by:
mustCompile
in classExpression
-
apply
public void apply(CallContext ctx) throws Throwable
Description copied from class:Expression
Evaluate the expression. This is named apply rather than eval so it is compatible with the full-tail-call calling convention, and we can stash an Expression in CallContext's proc field. FIXME - are we making use of this?- Overrides:
apply
in classExpression
- Throws:
Throwable
-
compile
public void compile(Compilation comp, Target target)
- Specified by:
compile
in classExpression
-
deepCopy
protected Expression deepCopy(IdentityHashTable mapper)
- Overrides:
deepCopy
in classExpression
-
visit
protected <R,D> R visit(ExpVisitor<R,D> visitor, D d)
- Overrides:
visit
in classExpression
-
visitChildren
protected <R,D> void visitChildren(ExpVisitor<R,D> visitor, D d)
- Overrides:
visitChildren
in classExpression
-
print
public void print(gnu.kawa.io.OutPort out)
- Specified by:
print
in classExpression
-
calculateType
protected Type calculateType()
