Constructor Detail

ExponentationExpression

public ExponentationExpression(EvaluableExpression base,
                               EvaluableExpression exponent)

Build an expression which returns the base raised to the power of the exponent.

Parameters:

exponent - The expression which is the exponent of this expression. Must not be null.

base - The expression which is the base of this expression. Must not be null.

Method Detail

getExponent

public EvaluableExpression getExponent()

Get the EvaluableExpression which is set as exponent.

Returns:

The expression's exponent.

getBase

public EvaluableExpression getBase()

Get the EvaluableExpression which is set as base.

Returns:

The expression's base.

receive

public void receive(EvaluableExpressionVisitor visitor)

Description copied from interface: EvaluableExpression

Calls the appropriate overload of EvaluableExpressionVisitor.visit(de.uka.ipd.sdq.beagle.core.evaluableexpressions.AdditionExpression) on visitor. This implements the well-known visitor pattern.

Specified by:

receive in interface EvaluableExpression

Parameters:

visitor - The visitor wishing to visit this expression.

evaluate

public double evaluate(EvaluableVariableAssignment variableAssignments)

Description copied from interface: EvaluableExpression

Calculates this expression’s value for the given variableAssignments.

Specified by:

evaluate in interface EvaluableExpression

Parameters:

variableAssignments - must assign a value to at least all EvaluableVariables contained in this expression.

Returns:

the value for the given assignments.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object object)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
