Owning Palette: FPGA Module VIs and Functions

Requires: FPGA Module. This topic might not match its corresponding palette in LabVIEW depending on your operating system, licensed product(s), and target.

Use the Cluster & Class functions to create and manipulate clusters.

Note  This palette is specific to FPGA targets and contains a subset of the VIs and functions that are on this palette when you edit a host VI.

Refer to the Cluster & Class Palette Details topic for information about Timed Loop compatibility, usage, timing, and resource considerations related to the objects on this palette.

Palette ObjectDescription
Array To ClusterConverts a 1D array to a cluster of elements of the same type as the array elements. Right-click the function and select Cluster Size from the shortcut menu to set the number of elements in the cluster.
BundleAssembles a cluster from individual elements.
Bundle By NameReplaces one or more cluster elements. This function refers to cluster elements by name instead of by their position in the cluster.
Call Parent MethodCalls the nearest ancestor implementation of a class method. You can use the Call Parent Method node only on the block diagram of a member VI that belongs to a class that inherits member VIs from an ancestor class. The child member VI must be a dynamic dispatching member VI and have the same name as the ancestor member VI.
Cluster ConstantUse this constant to supply a constant cluster value to the block diagram.
Cluster To ArrayConverts a cluster of elements of the same data type to a 1D array of elements of the same data type.
LV Object ConstantThe LabVIEW Object is the common ancestor data type for all LabVIEW classes. You can use the LabVIEW Object to create generic methods that can handle all LabVIEW class data types.
To More Generic ClassTypecasts a reference, such as a control or a type definition, to a more generic class in the inheritance hierarchy.
To More Specific ClassTypecasts a reference, such as a control or a type definition, to a more specific class in the inheritance hierarchy.
UnbundleSplits a cluster into each of its individual elements.
Unbundle By NameReturns the cluster elements whose names you specify.
