Extension Methods

Name	Description
GetAttachment<T>(ICMAttachmentBearer, CMSampleBufferAttachmentKey, CMAttachmentMode)
GetAttachment<T>(ICMAttachmentBearer, String, CMAttachmentMode)	Returns the attachment that is identifed by `key` and writes the attachment propagation mode to `attachmentModeOut`.
GetAttachments(ICMAttachmentBearer, CMAttachmentMode)	Returns an array of all the bearer's attachments and the attachment propagation mode to `attachmentMode`.
GetAttachments<TKey,TValue>(ICMAttachmentBearer, CMAttachmentMode)
PropagateAttachments(ICMAttachmentBearer, ICMAttachmentBearer)	Propagates the attachments that belong to `source` and are allowed to propagate to `destination`.
RemoveAllAttachments(ICMAttachmentBearer)	Removes all of `target`'s attachment.'
RemoveAttachment(ICMAttachmentBearer, String)	Removes the attachment that is identifed by `key`.
SetAttachment(ICMAttachmentBearer, String, INativeObject, CMAttachmentMode)	Attaches `value` to the bearer with the specified `key` and `attachmentMode`.
SetAttachments(ICMAttachmentBearer, NSDictionary, CMAttachmentMode)	Attaches `theAttachments` to the bearer with the specified `attachmentMode`.
