Constructor Detail

BinaryExpression

public BinaryExpression(Expression left,
                        Expression right)

Method Detail

getLeft

public Expression getLeft()

---

getRight

public Expression getRight()

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

hashCode

public int hashCode()

TODO: more efficient hashCode()

---

equals

public boolean equals(java.lang.Object o)

TODO: more efficient hashCode()

---

getExpressionSymbol

public abstract java.lang.String getExpressionSymbol()

Returns the symbol that represents this binary expression. For example, addition is represented by "+"

setRight

public void setRight(Expression expression)

---

setLeft

public void setLeft(Expression expression)
