Constructor Detail

TryExp

public TryExp(Expression try_clause,
              Expression finally_clause)

Method Detail

getCatchClauses

public final CatchClause getCatchClauses()

getFinallyClause

public final Expression getFinallyClause()

setCatchClauses

public final void setCatchClauses(CatchClause catch_clauses)

addCatchClause

public void addCatchClause(Declaration decl,
                           Expression body)

mustCompile

protected boolean mustCompile()

Specified by:

mustCompile in class Expression

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 class Expression

Throws:

Throwable

compile

public void compile(Compilation comp,
                    Target target)

Specified by:

compile in class Expression

visit

protected <R,D> R visit(ExpVisitor<R,D> visitor,
                              D d)

Overrides:

visit in class Expression

visitChildren

protected <R,D> void visitChildren(ExpVisitor<R,D> visitor,
                                         D d)

Overrides:

visitChildren in class Expression

calculateType

protected Type calculateType()

Overrides:

calculateType in class Expression

print

public void print(gnu.kawa.io.OutPort ps)

Specified by:

print in class Expression
