Detailed Description

Creates bank index for serialized event.

Note that a given tag/num may appear more than once in event and map.

Member Function Documentation

bankIndex evioBankIndex::getBankIndex	(	const evioDictEntry &	tn	)	const
throw	(	evioException
	)

Returns bankIndex given evioDictEntry, throws exception if no entry found.

Parameters

tn	evioDictEntry

Returns

bankIndex for evioDictEntry

template<typename T >

const T* evio::evioBankIndex::getData ( const evioDictEntry &  tn, int *  pLen  ) throw ( evioException )

inline

Returns length and pointer to data, NULL if container bank, bad evioDictEntry or wrong data type.

Parameters

tn	evioDictEntry
pLen	Pointer to int to receive data length, set to 0 upon error

Returns

Pointer to data, NULL on error

template<typename T >

const T* evio::evioBankIndex::getData ( const bankIndex &  bi, int *  pLen  ) throw ( evioException )

inline

Returns length and pointer to data, assumes valid bankIndex.

Parameters

bi	bankIndex
pLen	Pointer to int to receive data length, set to 0 for bad type

Returns

Pointer to data, NULL on bad type
