datatype_icon

name

The name of the attribute whose value you want to retrieve.

Note This input is not available if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

default value

A value and data type that you specify. This node returns default value if it does not find the attribute specified in name.

Note This input is not available if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Default value: No error

datatype_icon

variant out

variant unchanged.

datatype_icon

found?

A Boolean value that indicates whether the node found the attribute that is specified in name.

True The node found the attribute specified in name.
False The node did not find the attribute specified in name.
Note This output is replaced by a 1D array output containing the names of all of the attributes if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

names

A 1D array containing the names of all attributes associated with the variant.

This node sorts this array and arranges the array elements in ascending order using the same algorithm as Sort 1D Array.
Note This output is only available if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

value

The value associated with the attribute you wire to name in variant format.

Note This output is replaced by a 1D array output containing the values of all of the attributes if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

values

A 1D array containing the values associated with each attribute of the specified variant in variant format. The values in this array appear in the same order as their corresponding names appear in the names output.

You must convert each attribute value to an appropriate data type.

Note This output is only available if you click this node on the diagram and select Get All Attributes in the Behavior section of the Item tab.
datatype_icon

error out

Error information.

Modes of Behavior

This node has two modes of behavior depending on whether you select Get All Attributes in the Behavior section of the Item tab.

Get All Attributes Node Behavior
Selected The node returns the names of all attributes and their corresponding values in 1D arrays.
Not selected The node searches for only the specified attribute. The names output changes to a Boolean output called found and the values output changes to a variant output called value. If the node does not find the specified attribute(s), or if it cannot convert the attribute(s) to the default value, found is False, and value displays the contents of default value.
