remProp
|
The remProp function deletes the property {propName} from the property list
associated with the symbol {sym}. If the
{propName} does not exist, a value of false is returned;
otherwise a value of true is returned.
When to use The remProp 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.
(remProp sym prop) Removes the property binding, consisting of a property-Name and property-Descriptor.
Returns the Boolean value true if the property-Name was found, otherwise, returns
the Boolean value false
Here are a number of links to Lambda coding examples which contain this instruction in various use cases.
Here are the links to the data types of the function arguments. Here are also a number of links to functions having arguments with any of these data types.
