Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Specified by:

clone in interface Expression

Specified by:

clone in class AbstractExpression

Throws:

java.lang.CloneNotSupportedException

getExpressionName

public java.lang.String getExpressionName()

Description copied from interface: Expression

Return the expression name.

Returns:

the expression name

evalAsInt

public final int evalAsInt()

Description copied from interface: Expression

Evaluate the expression as an int. The result of the evaluation will be the same as Expression.eval(), but the evaluation engine will be able to optimize the computation by knwoing that the result is an int (primitive valeus are cached internally).

Specified by:

evalAsInt in interface Expression

Overrides:

evalAsInt in class AbstractExpression

Returns:

the result as an int

evalAsFloat

public final float evalAsFloat()

Description copied from interface: Expression

Evaluate the expression as a float. The result of the evaluation will be the same as Expression.eval(), but the evaluation engine will be able to optimize the computation by knwoing that the result is a float (primitive valeus are cached internally).

Specified by:

evalAsFloat in interface Expression

Overrides:

evalAsFloat in class AbstractExpression

Returns:

the result as a float

eval

public java.lang.Object eval()
                      throws java.lang.ArithmeticException

Description copied from interface: Expression

Evaluate the expression.

Returns:

the result

Throws:

java.lang.ArithmeticException
