args

public List<Core.Exp> args()

Returns the argument list (assuming that the arguments are a tuple or record).

Throws:

ClassCastException - if argument is not a tuple

arg

public Core.Exp arg(int i)

Description copied from class: Core.Exp

Returns the i^th argument.

Overrides:

arg in class Core.Exp

accept

public Core.Exp accept(Shuttle shuttle)

Description copied from class: AstNode

Specified by:

accept in class Core.Exp

accept

public void accept(Visitor visitor)

Description copied from class: AstNode

Accepts a visitor, calling the Shuttle.visit(net.hydromatic.morel.ast.Ast.Literal) method appropriate to the type of this node, and returning the result.

Overrides:

accept in class Core.BaseNode

unparse

AstWriter unparse(AstWriter w,
 int left,
 int right)

Specified by:

unparse in class AstNode

copy

public Core.Apply copy(Core.Exp fn,
 Core.Exp arg)

isConstant

public boolean isConstant()

Description copied from class: Core.Exp

Returns whether this expression is a constant.

Examples include literals 1, true, constructors applied to constants, records and tuples whose arguments are constant.

Overrides:

isConstant in class Core.Exp
