vlax-ldata-delete (AutoLISP)

(vlax-ldata-delete dict key [private])

Arguments

dict

A VLA-object, AutoCAD drawing entity object, or a string naming a global dictionary.

key

A string specifying the dictionary key.

private

If a non-nil value is specified for private and vlax-ldata-delete is called from a separate-namespace VLX, vlax-ldata-delete deletes private LISP data from dict.

Return Values

T, if successful; otherwise nil (for example, the data did not exist).

Examples

Add LISP data to a dictionary:

(vlax-ldata-put "dict" "key" '(1))
(1)

Use vlax-ldata-delete to delete the LISP data:

(vlax-ldata-delete "dict" "key")
T

If vlax-ldata-delete is called again to remove the same data, it returns nil because the data does not exist in the dictionary:

(vlax-ldata-delete "dict" "key")
nil
