Detailed Description#

This class manages arrays of Qt OPC UA types with associated array dimensions information. It is returned as value when a multidimensional array is received from the server. It can also be used as a write value or as parameter for filters and method calls.

class PySide6.QtOpcUa.QOpcUaMultiDimensionalArray#

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray(valueArray, arrayDimensions)

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray(arrayDimensions)

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray(other)

Parameters

arrayDimensions –
other – PySide6.QtOpcUa.QOpcUaMultiDimensionalArray
valueArray –

Constructs a multidimensional array with value value and array dimensions arrayDimensions.

Creates a multidimensional array with preallocated data fitting arrayDimensions.

Constructs a multidimensional array from other.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.arrayDimensions()#

Return type

Returns the dimensions of the multidimensional array. The element at position n contains the length of the n-th dimension.

setArrayDimensions()

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.arrayIndex(indices)#

Parameters: indices –
Return type: int

Returns the array index in valueArray() of the element identified by indices. If indices is invalid for the array or if the array’s dimensions don’t match the size of valueArray() , the invalid index -1 is returned.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.isValid()#

Return type: bool

Returns true if the multidimensional array is valid

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.__eq__(other)#

Parameters: other – PySide6.QtOpcUa.QOpcUaMultiDimensionalArray
Return type: bool

Returns true if this multidimensional array has the same value as other.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.setArrayDimensions(arrayDimensions)#

Parameters: arrayDimensions –

Sets the dimensions of the multidimensional array to arrayDimensions.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.setValue(indices, value)#

Parameters

indices –
value – object

Return type

bool

Sets the value at position indices to value. Returns true if the value has been successfully set.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.setValueArray(valueArray)#

Parameters: valueArray –

Sets the value array of the multidimensional array to value.

PySide6.QtOpcUa.QOpcUaMultiDimensionalArray.value(indices)#

Parameters: indices –
Return type: object

Returns the value of the element identified by indices. If the indices are invalid for the array, an empty QVariant is returned.
