Member Function Documentation

◆ assign()

StatusCode SG::VarHandleKey::assign ( const std::string & sgkey )

virtualinherited

Change the key of the object to which we're referring.

Parameters

sgkey The StoreGate key for the object.

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present the store is not changed. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

Returns failure the key string format is bad.

◆ owningHandle()

VarHandleBase* SG::VarHandleKey::owningHandle ( )

inherited

Return the VarHandle that owns this key, if any.

This should only be non-null for keys that are created automatically by a VarHandle when it is not created from a VarHandleKey. This should always be null for keys that are created explicitly.

◆ parseKey()

void SG::VarHandleKey::parseKey	(	const std::string &	key,
		const std::string &	storeName
	)

privateinherited

Handle assignment/construction from a string key.

Parameters

sgkey The StoreGate key for the referenced object.

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present, the store named by storeName is used. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

see implementation comments for further details

Parameters

sgkey The StoreGate key for the referenced object.

The provided key may actually start with the name of the store, separated by a "+": "MyStore+Obj". If no "+" is present the store named by storeName is used. A key name that starts with a slash is interpreted as a hierarchical key name, not an empty store name.

we also have to check that if the key contains the store name, it matches the store name that they Handle was constructed with

blank keys result in blank DataObjIDs
