DAO for CurrencyPairDO entities. Extends BaseDao<CurrencyPairDO>, inheriting standard CRUD operations, access control, and search. Provides merged history by also loading history entries from child CurrencyConversionRateDO records.

Architecture

Inheritance

BaseDao<CurrencyPairDO> — standard DAO with filtering, sorting, history, access checks

Dependencies

Dependency	Role
`CurrencyConversionService`	Used in `addOwnHistoryEntries()` to load all child rates for history merging

Default Sorting

By sourceCurrency then targetCurrency.

Autocompletion

Enabled for sourceCurrency and targetCurrency fields (3-letter currency codes).

History Merging

addOwnHistoryEntries() iterates over all child CurrencyConversionRateDO entries (including deleted) and merges their history into the parent's history context. This provides a unified audit trail showing both pair-level and rate-level changes.

Access Control

Guarded by UserRightId.FIBU_CURRENCY_CONVERSION, set in init.

Factory

newInstance() returns a bare CurrencyPairDO().
