Constructor & Destructor Documentation

StoreAccessorBase()

StoreAccessorBase ( const std::string &  name, DataStore::EDurability  durability, TClass *  objClass, bool  isArray  )

inline

Constructor to access an object or array in the DataStore.

Parameters

name	Name under which the object is stored in the DataStore.
durability	Decides durability map used for getting the accessed object.
objClass	Type of the object
isArray	true if the entry in the DataStore is an array

Definition at line 37 of file StoreAccessorBase.h.

~StoreAccessorBase()

virtual ~StoreAccessorBase ( )

inlinevirtual

Destructor.

Virtual because this is a base class.

Definition at line 44 of file StoreAccessorBase.h.

Member Function Documentation

assign()

bool assign	(	TObject *	object,
		bool	replace = false
	)

Assign 'object' to this accessor.

(takes ownership).

Parameters

object	The object that should be put in the DataStore, should be of same type as the one used by this accessor.
replace	Should an existing object be replaced? (if existing and supplied object are equal, this has no effect)

Returns

True if the assignment succeeded. If false, assign() will delete 'object', do not use it afterwards.

Definition at line 33 of file StoreAccessorBase.cc.

create()

bool create ( bool  replace = false )

inline

Create a default object in the data store.

This only works after registerInDataStore() has been called by this or another module.

Parameters

replace

Should an existing object be replaced?

Returns

True if the creation succeeded.

Definition at line 107 of file StoreAccessorBase.h.

getAccessorParams()

AccessorParams getAccessorParams ( ) const

inline

Return pair of name and durability under which stored object is saved.

Definition at line 134 of file StoreAccessorBase.h.

isOptional()

bool isOptional ( const std::string &  name = "" )

inline

Tell the DataStore about an optional input.

Mainly useful for creating diagrams of module inputs and outputs.

Parameters

name	If not empty, set non-default name for this object/array. This is permanent, so that e.g. after using registerInDataStore("myName") in initialize(), this object will continue refer to 'myName' in event().

Returns

True if the object/array exists.

Definition at line 93 of file StoreAccessorBase.h.

isRequired()

bool isRequired ( const std::string &  name = "" )

inline

Ensure this array/object has been registered previously.

Will cause an ERROR if it does not exist. This must be called in the initialization phase.

Parameters

name	If not empty, set non-default name for this object/array. This is permanent, so that e.g. after using registerInDataStore("myName") in initialize(), this object will continue refer to 'myName' in event().

Returns

True if the object/array exists.

Definition at line 78 of file StoreAccessorBase.h.

notWrittenOut()

bool notWrittenOut

(

)

const

Returns true if this object/array should not be saved by output modules.

See DataStore::c_DontWriteOut. Can be changed by re-registering it with/without the flag.

Definition at line 53 of file StoreAccessorBase.cc.

readableName()

std::string readableName

(

)

const

Convert this acessor into a readable string (for messages).

e.g. "object EventMetaData (durability: event)"

Definition at line 18 of file StoreAccessorBase.cc.

registerInDataStore() [1/2]

bool registerInDataStore ( const std::string &  name, DataStore::EStoreFlags  storeFlags = DataStore::c_WriteOut  )

inline

Register the object/array in the DataStore.

This must be called in the initialization phase.

Parameters

name	If not empty, set non-default name for this object/array. This is permanent, so that e.g. after using registerInDataStore("myName") in initialize(), this object will continue refer to 'myName' in event().
storeFlags	ORed combination of DataStore::EStoreFlags.

Returns

True if the registration succeeded.

Definition at line 64 of file StoreAccessorBase.h.

registerInDataStore() [2/2]

bool registerInDataStore ( DataStore::EStoreFlags  storeFlags = DataStore::c_WriteOut )

inline

Register the object/array in the DataStore.

This must be called in the initialization phase.

Parameters

storeFlags

ORed combination of DataStore::EStoreFlags.

Returns

True if the registration succeeded.

Definition at line 52 of file StoreAccessorBase.h.
