Class Meta.Tickers

java.lang.Object

com.micex.client.Meta.Tickers

Enclosing class:

Meta

public static class Meta.Tickers
extends Object

ASTS scale information container. Contains scale of ASTS securities - number of decimal places in price values. This information is important for encoding requests and parsing responses and is usually populated as a side-effect of processing results of a securities request ("SECURITIES" table, same as Meta.Messages.find(com.micex.client.Meta.TableType) with Meta.TableType.Securities. Another option is to share decimals information of the first Client instance with the second and subsequent instances when you are pretty sure that they are connected to the same ASTS instance. That way the second instance can skip a long-running loading and parsing of "SECURITIES" table. Instance methods are synchronized with ReadWriteLock and can be safely used by multiple clients and parsers between threads.

Clears any stored scale information.

get

public int get(String board,
               String paper,
               int fallback)

Gets scale of the security identified by both board and paper.

Parameters:

board - - security board (SECBOARD as known in ASTS).

paper - - security paper (SECCODE as known in ASTS).

fallback - - value to return when no match found.

Returns:

number of decimal places in price (scale)

Parameters:

paper - - security paper (SECCODE as known in ASTS).

fallback - - value to return when no match found.

Returns:

number of decimal places in price (scale)

set

public void set(String board,
                String paper,
                int decimals)

Sets scale of the security identified by both board and paper. Overrides any previous information if any.

Parameters:

board - - security board (SECBOARD as known in ASTS).

paper - - security paper (SECCODE as known in ASTS).

decimals - - security scale.
