Field Detail

lhs

public final Java.Rvalue lhs

The left hand side operand.

operator

public final java.lang.String operator

The operator, as an interned string.

See Also:

Java.BinaryOperation

rhs

public final Java.Rvalue rhs

The right hand side operand.

Constructor Detail

BinaryOperation

public BinaryOperation(Location location,
                       Java.Rvalue lhs,
                       java.lang.String operator,
                       Java.Rvalue rhs)

Method Detail

toString

public java.lang.String toString()

Specified by:

toString in class Java.Atom

unrollLeftAssociation

public java.util.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 java.lang.Throwable> R accept(Visitor.RvalueVisitor<R,EX> visitor)
                                                  throws EX extends java.lang.Throwable

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 extends java.lang.Throwable
