All Superinterfaces:

ILcdExpression<T>

public interface ILcdParameter<T>
extends ILcdExpression<T>

This interface describes an expression whose result can vary at any time without changing the expression.

You must never implement this interface yourself. You must always construct one using TLcdExpressionFactory.parameter(java.lang.String, T).

Components that use this expression (or this expression nested in other expressions) are automatically notified when the value is changed.

In particular for layers and painters, it is not necessary to fire style change events.

Since:
