Detailed Description

The SelectorKeys class represents the key list for a single variant.

It corresponds to the keys array in the Variant interface defined in https://github.com/unicode-org/message-format-wg/blob/main/spec/data-model.md#messages

SelectorKeys is immutable, copyable and movable.

Constructor & Destructor Documentation

◆ SelectorKeys() [1/2]

icu::message2::data_model::SelectorKeys::SelectorKeys ( )

inline

Default constructor.

Puts the SelectorKeys into a valid but undefined state.

◆ SelectorKeys() [2/2]

icu::message2::data_model::SelectorKeys::SelectorKeys ( const SelectorKeys & other )

Copy constructor.

Deprecated:: This API is for technology preview only.

◆ ~SelectorKeys()

virtual icu::message2::data_model::SelectorKeys::~SelectorKeys ( )

Member Function Documentation

◆ getKeys()

std::vector<Key> icu::message2::data_model::SelectorKeys::getKeys ( ) const

inline

Returns the underlying list of keys.

Returns: The list of keys for this variant. Returns an empty list if allocating this SelectorKeys object previously failed.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

Definition at line 530 of file messageformat2_data_model.h.

◆ operator<()

bool icu::message2::data_model::SelectorKeys::operator< ( const SelectorKeys & other ) const

Less than operator.

Compares the two key lists lexicographically. This method makes it possible for a SelectorKeys to be used as a map key, which allows variants to be represented as a map. It is not expected to be useful otherwise.

Parameters

other The SelectorKeys to compare to this one.

Returns: true if this is less than other, comparing the two key lists lexicographically. Returns false otherwise.

◆ operator=()

SelectorKeys& icu::message2::data_model::SelectorKeys::operator= ( SelectorKeys other )

noexcept

Assignment operator.
