Method Detail

initialize

public void initialize(FormulaContext context)
                throws EvaluationException

Specified by:

initialize in interface LValue

Overrides:

initialize in class AbstractLValue

Throws:

EvaluationException

evaluate

public TypeValuePair evaluate()

toString

public String toString()

Overrides:

toString in class Object

isConstant

public boolean isConstant()

Checks whether the LValue is constant. Constant lvalues always return the same value.

Returns:

getValue

public Object getValue()

getValueType

public Type getValueType()

This function allows a program traversing the LibFormula object model to know what type this static value is.

Specified by:

getValueType in interface LValue

Overrides:

getValueType in class AbstractLValue

Returns:

the type of the static value
