#include "comms/field/ArrayList.h"

Detailed Description

template<typename TFieldBase, typename TElement, typename... TOptions>
class comms::field::ArrayList< TFieldBase, TElement, TOptions >

Field that represents a sequential collection of fields.

By default uses std::vector, for internal storage, unless comms::option::app::FixedSizeStorage option is used, which forces usage of comms::util::StaticVector instead.

Template Parameters

TFieldBase	Base class for this field, expected to be a variant of comms::Field.
TElement	Element of the collection, can be either basic integral value (such as std::uint8_t) or any other field from comms::field namespace. For example: using MyFieldBase = comms::Field<comms::option::def::BigEndian>; using RawDataSeqField = comms::field::ArrayList< MyFieldBase, std::uint8_t >; using CollectionOfBundlesField = comms::field::ArrayList< MyFieldBase, std::field::Bundle< MyFieldBase, std::tuple< comms::field::IntValue<MyFieldBase, std::uint16_t> comms::field::IntValue<MyFieldBase, std::uint8_t> comms::field::IntValue<MyFieldBase, std::uint8_t> > > >; comms::Field Base class to all the field classes. Definition Field.h:33 comms::field::ArrayList Field that represents a sequential collection of fields. Definition ArrayList.h:192 comms::field::IntValue Field that represent integral value. Definition IntValue.h:72
TOptions	Zero or more options that modify/refine default behaviour of the field. Supported options are: comms::option::app::FixedSizeStorage comms::option::app::CustomStorageType comms::option::app::OrigDataView (valid only if TElement is integral type of 1 byte size. comms::option::def::SequenceSizeFieldPrefix comms::option::def::SequenceSerLengthFieldPrefix comms::option::def::SequenceElemSerLengthFieldPrefix comms::option::def::SequenceElemFixedSerLengthFieldPrefix comms::option::def::SequenceSizeForcingEnabled comms::option::def::SequenceLengthForcingEnabled comms::option::def::SequenceFixedSize comms::option::def::SequenceTerminationFieldSuffix comms::option::def::SequenceTrailingFieldSuffix comms::option::def::DefaultValueInitialiser comms::option::def::HasCustomRead comms::option::def::HasCustomRefresh comms::option::def::FailOnInvalid comms::option::def::IgnoreInvalid comms::option::def::EmptySerialization comms::option::def::VersionStorage comms::option::def::FieldType

Write current field value to output data sequence.

By default, the write operation will write all the elements the field contains. If comms::option::def::SequenceFixedSize option is used, the number of elements, that is going to be written, is exactly as the option specifies. If underlying vector storage doesn't contain enough data, the default constructed elements will be appended to the written sequence until the required amount of elements is reached.
