Class ArgumentDeclarator

java.lang.Object

de.intarsys.tools.functor.ArgumentDeclarator

public class ArgumentDeclarator
extends Object

An argument declaration strategy that modifies its input IArgs according to the IDeclaration.

Every ArgumentDeclaration instance is applied to the input args.

• A name is associated
• An optional default is assigned
• An optional type casting is applied

The ArgumentDeclarator knows three declaration "modes".

• !strict (default)
Any input args are preserved, declared args are applied or added.
• strict && !lazy
Only input args that occur in the declaration are preserved, all others cleared.
• strict && lazy
If there are no ArgumentDeclaration declarations, the input args are preserved. If there is any ArgumentDeclaration, the behavior switches to "strict".
