putprop

 

 

Overview

The putprop function adds the property-descriptor {propDesc} and the property-name {propName} to the named symbol {sym}. If the {propName} already exists, the new value {val} replaces the old value.

Usage

The putprop function is a function defined as part of the standard Lisp language. There are five functions that deal with assigning, acquiring and removing a property from a property list of a symbol: putProp, getProp, proplist, proprecord, and remProp. The notion of a property for a symbol consists one or more property bindings: a property-descriptor followed by a property-name. While Lisp supports the traditional Lisp functions for properties, the Structure and Dictionary objects offer a more flexible way of storing attribute bindings.
