Object$load: Static method to load an Object from a file or a connection

Description

Static method to load an Object from a file or a connection, which previously have been saved using save() of class Object.

Usage

## Static method (use this):
## Object$load(file, path=NULL, ...)
## Don't use the below:
# S3 method for Object
load(static, file, path=NULL, ...)

Arguments

file

Filename or connection from where to read the Object.

path

The path where the file exists.

...

Not used.

Value

Returns a reference to the loaded Object.

Type control

Typically this static method is called as <Object>$load(...) where <Object> is any Object class. When an Object has been loaded, it is verified that it inherits from <Object>. If it does not, an exception is thrown. Thus, Object$load(...) will load any Object, but MyClass$load(...) will only load an Object that inherits from MyClass. If loaded object is not of correct class, an exception is thrown.

Troubleshooting

Due to a bug, likely in R itself, one can not specify the file argument by its name, i.e. Object$load(file="foo.RData") will not work, but Object$load("foo.RData") work just fine.

Details

Please note that no constructors are called when an Object is loaded and neither is any static class code called.
