Function Schema

Create a schema that matches a function.

See at Base Schema for the inherited methods you may call like:

• title()
• detail()
• required()
• forbidden()
• default()
• raw()

1. Checking arguments

The number of arguments which have to be there may be checked. Splats and parameter with default values are not counted here.

1.1. min(limit) / max(limit) / length(limit)

Specifies the number of arguments the function needs to have.

• limit gives the fix number
• min and max defines a range

const schema = new FunctionSchema().min(1).max(3)
schema.min().max() // to remove both settings
const schema = new FunctionSchema().length(3)

References are also possible:

const ref = new Reference(5)
const schema = new FunctionSchema().length(ref)
