PowerPoint.CustomPropertyCollection class

Package:

powerpoint

A collection of custom properties.

Extends

OfficeExtension.ClientObject

Remarks

[ API set: PowerPointApi 1.7 ]

Properties

context	The request context associated with the object. This connects the add-in's process to the Office host application's process.
items	Gets the loaded child items in this collection.

Methods

add(key, value)	Creates a new CustomProperty or updates the property with the given key.
deleteAll()	Deletes all custom properties in this collection.
getCount()	Gets the number of custom properties in the collection.
getItem(key)	Gets a CustomProperty by its key.
getItemOrNullObject(key)	Gets a CustomProperty by its key. If the CustomProperty doesn't exist, then this method returns an object with its isNullObject property set to true. For further information, see *OrNullObject methods and properties.
load(options)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
toJSON()	Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that's passed to it.) Whereas the original PowerPoint.CustomPropertyCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as PowerPoint.Interfaces.CustomPropertyCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
