Constructor Detail

StatementExpression

public StatementExpression(java.lang.String leftHandSide,
                           java.lang.String equalSymbol,
                           java.lang.String postfix,
                           int type,
                           int sign)

Method Detail

interpret

public boolean interpret(Context c)
                  throws ParserException

Description copied from class: AbstractRegularExpression

Parses this expression, possibly using Context to fetch the String to interpret if this Expression is a leaf expression.

Specified by:

interpret in class AbstractRegularExpression

---

getValue

public java.lang.Number getValue()

Return the value of the RHS, wrapped in a Number (either Integer or Double)

---

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()).
