Description¶

Subclass TBAValueSet to create enumeration type attributes. The attribute wizard (accessible through the "Bold | Bold Attribute Wizard" menu) is the easiest way to create custom attributes.

Properties¶

AsInteger¶

property AsInteger: Integer;

ContentAsInteger¶

property ContentAsInteger: Integer;

Values¶

property Values: TBAValueSetValueList;

Assign¶

procedure Assign(Source: TBoldElement); override; See also Ancestor Method

AssignContentValue¶

procedure AssignContentValue(Source: IBoldValue); override; See also Ancestor Method

AssignValue¶

procedure AssignValue(Source: IBoldValue); override; See also Ancestor Method

CanSetValue¶

function CanSetValue(NewValue: TBAValueSetValue; Subscriber: TBoldSubscriber): Boolean;

Use this function to test if it is allowed to set the attribute to a specific value.

If a subscriber is sent to the function, this subscriber will be notified if the conditions have changed (so that an illegal value is now legal). It is OK to send a nilpointer instead.

CompareToAs¶

function CompareToAs(CompType: TBoldCompareType; BoldElement: TBoldElement): Integer; override; See also Ancestor Method

CompareToEnumLiteral¶

function CompareToEnumLiteral(const str: String): Boolean; virtual;

This function is used internally by the OCL-evaluator

GetAsVariant¶

function GetAsVariant: Variant; override; See also Ancestor Method

GetContentAsInteger¶

function GetContentAsInteger: Integer; virtual;

GetStringRepresentation¶

function GetStringRepresentation(Representation: TBoldRepresentation): string; override; See also Ancestor Method

GetValues¶

function GetValues: TBAValueSetValueList; virtual; abstract;

InitializeMember¶

procedure InitializeMember(OwningElement: TBoldDomainElement; ElementTypeInfo: TBoldElementTypeInfo); override; See also Ancestor Method

MaySetValue¶

function MaySetValue(NewValue: TBAValueSetValue; Subscriber: TBoldSubscriber): Boolean; virtual;

A subclass of TBAValueSet may override this method to prohibit setting the attribute to a specific value. If the result value is false, the setting will be aborted. If it is true, there may still be other reasons why the changing of the value is not allowed.

ProxyClass¶

function ProxyClass: TBoldMember_ProxyClass; override; See also Ancestor Method

ProxyInterface¶

function ProxyInterface(const IId: TGUID; Mode: TBoldDomainElementProxyMode; out Obj): Boolean; override; See also Ancestor Method

SetAsVariant¶

procedure SetAsVariant(const Value: Variant); override; See also Ancestor Method

SetEmptyValue¶

procedure SetEmptyValue; override; See also Ancestor Method

SetStringRepresentation¶

procedure SetStringRepresentation(Representation: TBoldRepresentation; Value: string); override; See also Ancestor Method

ValidateCharacter¶

function ValidateCharacter(C: AnsiChar; Representation: TBoldRepresentation): Boolean; override; See also Ancestor Method

ValidateString¶

function ValidateString(Value: string; Representation: TBoldRepresentation): Boolean; override; See also Ancestor Method
