Property Documentation

Attributes

MetaAttributeList Attributes

get

A modifiable collection with all metadata attributes.

The default value of this property is an empty collection which can be modified but it cannot be replaced.

Immutable

bool Immutable

get

Returns whether the object is immutable.

An immmutable object cannot be modified and all modifying methods fail to produce a result.

An immutable object can be modified by the AVBlocks library.

Object immutability spreads to all nested objects. Therefore it is not possible to add/set an immutable object to a mutable object.

When cloned an immutable object becomes mutable.

Pictures

MetaPictureList Pictures

get

A modifiable collection with all metadata pictures.

The default value of this property is an empty collection which can be modified but it cannot be replaced.
