详细描述

This is a fixed size datapoint type with the length of 4 bytes that stores an access identification code, additional 属性 , and an index.

Access identification codes consist of six digits, each between 0 and 9. Only a card or key number should be used. A system number, version number, country code, and so on, are not necessary. A ciphered access identification code should be possible in principle. If 24 bits are not necessary, the most significant positions shall be set to zero.

The range of the value is from Low Code, 0 0 0 0 0 0 to High Code, 9 9 9 9 9 9 .

成员类型文档编制

enum QKnxEntranceAccess:: 属性
flags QKnxEntranceAccess:: 属性

This enum holds the access identification code attributes.

常量	值	描述
`QKnxEntranceAccess::Error`	`0x01`	Whether the controlling device could successfully read the access identification code.
`QKnxEntranceAccess::PermissionAccepted`	`0x02`	Whether the controlling device granted the access.
`QKnxEntranceAccess::ReadRightToLeft`	`0x04`	Sets the reading direction of a device used for access, such as a badge, to be from right to left. Not needed for devices such as electronic keys, and can be set to zero.
`QKnxEntranceAccess::Encrypted`	`0x08`	Whether the access identification code is encrypted.

The Attributes type is a typedef for QFlags <Attribute>. It stores an OR combination of Attribute values.

QKnxEntranceAccess:: QKnxEntranceAccess ( quint32 idCode , QKnxEntranceAccess::Attributes 属性 , quint8 index )

Creates a fixed size datapoint type with the access identification code set to idCode , attributes to 属性 , and the index to index .

QKnxEntranceAccess:: QKnxEntranceAccess ()

Creates a fixed size datapoint type with the value set to 0 and an empty list of attributes.

QKnxEntranceAccess::Attributes QKnxEntranceAccess:: 属性 () const

Returns the additional information stored in the datapoint type as a list of attributes.

qint8 QKnxEntranceAccess:: digit ( quint8 x ) const

Returns the digit x of the access identification code or a negative value if the datapoint is invalid or x is not in the range from 1 to 6 .

bool QKnxEntranceAccess:: isSet ( QKnxEntranceAccess::Attribute 属性 ) const

返回 true if 属性已设置；否则返回 false .

`[override virtual]` bool QKnxEntranceAccess:: isValid () const

重实现： QKnxDatapointType::isValid () const.

bool QKnxEntranceAccess:: removeAttribute ( QKnxEntranceAccess::Attribute 属性 )

移除属性 from the list of attributes.

返回 true if the attribute was removed; otherwise returns false .

bool QKnxEntranceAccess:: setAttribute ( QKnxEntranceAccess::Attribute 属性 )

添加属性 to the list of attributes.

返回 true if the attribute was set; otherwise returns false .

另请参阅 属性 .

bool QKnxEntranceAccess:: setAttributes ( QKnxEntranceAccess::Attributes 属性 )

Sets the additional information of the datapoint type to the list of attributes specified by 属性 .

返回 true if the value was set; otherwise returns false .
