public DebugExpression(ASTInfo info,
                       Expression expression,
                       ExpressionOrigin origin)

Constructs a new debug expression.

Parameters:

info -

expression -

origin -

Method Detail

getExpression

public Expression getExpression()

Returns the wrapped expression.

Returns:

the wrapped expression

getOrigin

public ExpressionOrigin getOrigin()

Returns the expression origin (needed as a debug information).

Returns:

the expression origin

accept

public <T,E extends Throwable> T accept(ExpressionVisitor<T,E> visitor)
                                 throws E extends Throwable

Description copied from class: Expression

Accepts visitor.

Specified by:

accept in class Expression

Returns:

the result of visit

Throws:

E

E extends Throwable

basicInterpret

protected Object basicInterpret(Interpreter interpreter,
                                InterpreterStackTrace stackTrace)
                         throws ErrorException
