All actual FinOrder derived order classes can only be created through their corresponding FinOrderBuilder derived class. Thus, to create an order, the first step is to create the appropriate FinOrderBuilder derived class. For example: In order to create an account balance inquiry order, the first step is to create a FinAcctBalBuilder instance. Then its Build(FinAcct, Boolean) method must be called, which will return a new FinAcctBal instance, derived from FinOrder. An FinOrderBuilder derived class needs only be created once and can be used to create any number of orders.

The second task of all FinOrderBuilder derived classes is to provide convenient access to the bank parameter data associated with their type of order. Derived classes usually make bank parameter data available as simple objcet properties.

Classes that derive from FinOrderBuilder must call Init(FinOrderSegmentInfo[]) in order to initialise the order builder.

TanRequired

Indicates whether a TAN is required when sending an order of the derived type.

Declaration

public bool TanRequired { get; }

Type	Description
System.Boolean	If this is `true` , then a TAN is required, if this is `false` , then no TAN is required. In the latter case, there is still a PIN required, unless MinSignatures is zero, too.

TanSecuritySupported

Indicates whether an order of the derived type may be sent using PIN/TAN security.

Declaration

public bool TanSecuritySupported { get; }

Property Value

Type	Description
System.Boolean
