Detailed Description

Reads and writes currencies off of data storage.

Member Function Documentation

read_latest()

std::vector< domain::currency > read_latest	(	context	ctx,
		std::uint32_t	offset,
		std::uint32_t	limit
	)

Reads latest currencies with pagination support.

Parameters

ctx	Repository context with database connection
offset	Number of records to skip
limit	Maximum number of records to return

Returns

Vector of currencies within the specified range

get_total_currency_count()

std::uint32_t get_total_currency_count

(

context

ctx

)

Gets the total count of active currencies.

Parameters

ctx	Repository context with database connection

Returns

Total number of currencies with valid_to == max_timestamp

remove()

void remove	(	context	ctx,
		const std::string &	iso_code
	)

Deletes a currency by closing its temporal validity.

Sets the valid_to timestamp to now, effectively "deleting" the currency from the current point in time onwards while preserving history.
