Collection abstract base class.

This class describes the base protocol all collection classes have to implement. The ROOT collection classes always store pointers to objects that inherit from TObject. They never adopt the objects. Therefore, it is the user's responsibility to take care of deleting the actual objects once they are not needed anymore. In exceptional cases, when the user is 100% sure nothing else is referencing the objects in the collection, one can delete all objects and the collection at the same time using the Delete() function.

Collections can be iterated using an iterator object (see TIterator). Depending on the concrete collection class there may be some additional methods of iterating. See the respective classes.

TCollection inherits from TObject since we want to be able to have collections of collections.

In a later release the collections may become templatized.

Default print for collections, calls Print(option, 1).

This will print the collection header and Print() methods of all the collection entries.

If you want to override Print() for a collection class, first see if you can accomplish it by overriding the following protected methods:

void        PrintCollectionHeader(Option_t* option) const;
const char* GetCollectionEntryName(TObject* entry) const;
void        PrintCollectionEntry(TObject* entry, Option_t* option, Int_t recurse) const;

Otherwise override the Print(Option_t *option, Int_t) variant. Remember to declare:

using TCollection::Print;

somewhere close to the method declaration.

void TCollection::Print	(	Option_t *	option,
		Int_t	recurse
	)		const

virtual

Print the collection header and its elements.

If recurse is non-zero, descend into printing of collection-entries with recurse - 1. This means, if recurse is negative, the recursion is infinite.

Option is passed recursively.

Reimplemented in TProofOutputList.

void TCollection::Print	(	Option_t *	option,
		const char *	wildcard,
		Int_t	recurse = `1`
	)		const

virtual

Print the collection header and its elements that match the wildcard.

If recurse is non-zero, descend into printing of collection-entries with recurse - 1. This means, if recurse is negative, the recursion is infinite.

Option is passed recursively, but wildcard is only used on the first level.

Reimplemented in TProofOutputList.

void TCollection::SetOwner ( Bool_t enable = kTRUE )

virtual

Set whether this collection is the owner (enable==true) of its content.

If it is the owner of its contents, these objects will be deleted whenever the collection itself is delete. The objects might also be deleted or destructed when Clear is called (depending on the collection).

Int_t TCollection::Write	(	const char *	name = `0`,
		Int_t	option = `0`,
		Int_t	bsize = `0`
	)

virtual

Write all objects in this collection.

By default all objects in the collection are written individually (each object gets its own key). Note, this is recursive, i.e. objects in collections in the collection are also written individually. To write all objects using a single key specify a name and set option to TObject::kSingleKey (i.e. 1).
