Detailed Description

Encapsulates operations over FIX Repeating Group.

Repeating group represents array of repeating group instances, So, class exposes corresponding services to manipulate array of repeating group instances. Similar to the GroupInstance it behaves like a pointer/reference to the underlying data. It's a light-weight object which just wraps internal data.

Group remains valid until corresponding field (which defines size/length of repeating group) from field-set (message or outer repeating group instance) is updated.

const GroupInstance at

(

size_t

index

)

const

Accesses to repeating group instance.

Exceptions

std::exception

if If index exceeds allowed bounds.

Warning

Due to performance considerations, instance is not checked for validness. Member must be used only when instance is in valid state.

const Message & message ( ) const

inline

Instance of Message holding given repeating group instance.

Warning

Due to performance considerations, doesn't check whether instance refers to a valid set of fields. Use operator bool() to check whether instance is in valid state.

const GroupInstance operator[]

(

size_t

index

)

const

Accesses to repeating group instance.

Does NOT check index validness.

Warning

Due to performance considerations, instance is not checked for validness. Member must be used only when instance is in valid state.

size_t size

(

)

const

Return number of instances in repeating group.

Warning
