org.codehaus.janino.Java.BinaryOperation

All Implemented Interfaces:: Java.ArrayInitializerOrRvalue, Java.ElementValue, Java.Locatable

Enclosing class:: Java

public static final class Java.BinaryOperation extends Java.BooleanRvalue

Representation of all non-operand-modifying binary operations.

Operations with boolean result:

||: JLS7 15.24 "conditional or operation"
&&: JLS7 15.23 "conditional and operation"
==: JLS7 15.21 "equality operation"
!=: JLS7 15.22 "non-equality operation"
< > <= >=: JLS7 15.20.1 "numerical comparison operations"

Operations with non-boolean result:

|: JLS7 15.22.1 "integer bitwise OR operation" and JLS7 15.22.2 "boolean logical OR operation"
^: JLS7 15.22.1 "integer bitwise XOR operation" and JLS7 15.22.2 "boolean logical XOR operation"
&: JLS7 15.22.1 "integer bitwise AND operation" and JLS7 15.22.2 "boolean logical AND operation"
* / %: JLS7 15.17 "multiplicative operations"
+ -: JLS7 15.18 "additive operations"
<< >> >>>: JLS7 15.19 "shift operations"

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.
Constructor Details
- BinaryOperation
  
  public BinaryOperation(Location location, 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
