getFunction

public java.lang.String getFunction(int ref)

Returns the name of the function with a given reference number.

Parameters:

ref -

Returns:

the name of the function

staticGetFunction

public static java.lang.String staticGetFunction(int ref)

getConstantValue

protected abstract java.lang.Object getConstantValue(short ref)

init

public void init(Jep j)

Description copied from interface: JepComponent

Initialize the component. This methods is called whenever a component is added to Jep. Hence it allows components to keep track of the other components they may rely on.

Specified by:

init in interface JepComponent

Parameters:

j - the current Jep instance

getLightWeightInstance

public JepComponent getLightWeightInstance()

Return null

Specified by:

getLightWeightInstance in interface JepComponent

Returns:

either an new instance, or 'this'.
