Extract: Extract or Replace Parts of a Class or Instance

In oops: S3 Style Object Oriented Programming

Extract or Replace Parts of a Class or Instance

Description

Operators acting on oClass generators and their instances.

Usage

## S3 method for class 'ClassGenerator'
x$name

## S3 method for class 'ClassGenerator'
x[[i, exact = TRUE, inherits = TRUE]]

## S3 replacement method for class 'ClassGenerator'
x$name <- value

## S3 replacement method for class 'ClassGenerator'
x[[name]] <- value

## S3 method for class 'Instance'
x$name

## S3 method for class 'Instance'
x[[i, exact = TRUE, inherits = TRUE]]

Arguments

x	object of class "Instance" or "ClassGenerator"
i, name	character or symbol for `$` describing field name to return or set
exact	logical controlling whether a partial match is acceptable. Defaults to TRUE for no partial matching
inherits	logical describing whether parent environments should be searched
value	new field value

Details

For oClass instances, `$` and `[` first search the instance environment for the object. If no object is found, then all inherited objects are searched in order. Any object assigned to the instance will be inserted into the instance's environment. These operators act on the underlying Class template environment when applied to a Class generator.

Value

Environment of class "Instance" or function of class "ClassGenerator"
