entity: get the max value vector length for an entity

In struct: Statistics in R Using Class-based Templates

Description

A base class in the struct package. Not normally called directly. An entity object is used to store information about a parameter or output_ The standard 'name','description' and 'type' slots are included, along with 'value' for storing the value of the parameter and 'max_length' for restricting the length of 'value' if needed.

Usage

max_length(obj)

entity(
  name,
  description = character(0),
  type = "character",
  value = NULL,
  max_length = Inf
)

## S4 method for signature 'entity'
value(obj)

## S4 replacement method for signature 'entity'
value(obj) <- value

## S4 method for signature 'entity'
max_length(obj)

## S4 replacement method for signature 'entity'
max_length(obj) <- value

Arguments

obj	An entity object
name	the name of the object
description	a description of the object
type	the type of the struct object
value	The value of the parameter/outputs
max_length	Maximum length of value vector (default 1)

Details

Entity objects are usually defined in the prototype of another object, but can be extracted using param_obj and output_obj.

Value

max value vector length for an entity

An entity object

Examples

# Create a new entity object
E = entity(
    name = 'example',
    description = 'this is an example',
    type = 'numeric',
    value = 1
)

# Get/set the value of the entity object
value(E)
value(E) = 10
