Field Details

lhs

public final Java.Rvalue lhs

The left hand side operand.

operator

public final String operator

The operator, as an interned string.

See Also:

• Java.BinaryOperation

rhs

public final Java.Rvalue rhs

The right hand side operand.

BinaryOperation

 Java.Rvalue lhs,
 String operator,
 Java.Rvalue rhs)

Method Details

toString

public String toString()

Specified by:

toString in class Java.Atom

unrollLeftAssociation

public Iterator<Java.Rvalue> unrollLeftAssociation()

Transforms this binary operation into an Iterator over a left-to-right sequence of Java.Rvalues.

That iterator produces two elements (the left-hand-side and the right-hand-side of this operation), or, iff the left-hand-side of this operation is itself a binary operation with the same operator, then the iterator produces the sequence of the unrolled operands.

accept

@Nullable
public <R, EX extends Throwable> R accept(Visitor.RvalueVisitor<R,EX> visitor)
                                   throws EX

Description copied from class: Java.Rvalue

Invokes the "visit...()" method of Visitor.RvalueVisitor for the concrete Java.Rvalue type.

Specified by:

accept in class Java.Rvalue

Throws:

EX
