详细描述

This is the Qt OPC UA representation for the Argument type defined in OPC UA 1.05 part 3, 8.6.

The Argument type is mainly used for the values of the InputArguments and OutputArguments properties which describe the parameters and return values of method nodes.

QOpcUaArgument:: QOpcUaArgument ()

Default constructs an argument with no parameters set.

QOpcUaArgument:: QOpcUaArgument (const QString & name , const QString & dataTypeId , qint32 valueRank , const QList < quint32 > & arrayDimensions , const QOpcUaLocalizedText & description )

Constructs an argument with name name , data type id dataTypeId , value rank valueRank , array dimensions arrayDimensions and description description .

QList < quint32 > QOpcUaArgument:: arrayDimensions () const

Returns the array dimensions of the argument.

The array dimensions describe the length of each array dimension.

另请参阅 setArrayDimensions ().

QList < quint32 > &QOpcUaArgument:: arrayDimensionsRef ()

Returns a reference to the array dimensions of the argument.

QString QOpcUaArgument:: dataTypeId () const

Returns the data type node id of the argument.

另请参阅 setDataTypeId ().

QOpcUaLocalizedText QOpcUaArgument:: description () const

Returns the description of the argument.

另请参阅 setDescription ().

QString QOpcUaArgument:: name () const

Returns the name of the argument.

另请参阅 setName ().

void QOpcUaArgument:: setArrayDimensions (const QList < quint32 > & arrayDimensions )

Sets the array dimensions of the argument to arrayDimensions .

另请参阅 arrayDimensions ().

void QOpcUaArgument:: setDataTypeId (const QString & dataTypeId )

Sets the data type node id of the argument to dataTypeId .

另请参阅 dataTypeId ().

void QOpcUaArgument:: setDescription (const QOpcUaLocalizedText & description )

Sets the description of the argument to description .

另请参阅 description ().

void QOpcUaArgument:: setName (const QString & name )

Sets the name of the argument to name .

另请参阅 name ().

void QOpcUaArgument:: setValueRank ( qint32 valueRank )

Sets the value rank of the argument to valueRank .

另请参阅 valueRank ().

qint32 QOpcUaArgument:: valueRank () const

Returns the value rank of the argument. The value rank describes the structure of the value.

ValueRank	含义
-3	Scalar or one dimensional array
-2	Scalar or array with any number of dimensions
-1	Not an array
0	Array with one or more dimensions
1	One dimensional array
>1	Array with n dimensions

另请参阅 setValueRank ().

QVariant QOpcUaArgument:: operator QVariant () const

Converts this argument to QVariant .

QOpcUaArgument &QOpcUaArgument:: operator= (const QOpcUaArgument & rhs )

设置值从 rhs in this argument.

bool QOpcUaArgument:: operator== (const QOpcUaArgument & other ) const

Returns true if this argument has the same value as other .
