Determine whether object is a coder.descriptor.LookupTableDataInterface object

Since R2020a


lookupTableDataInterface = isLookupTableDataInterface(parameterObj)


lookupTableDataInterface = isLookupTableDataInterface(parameterObj) returns a logical value indicating whether the object is a coder.descriptor.LookupTableDataInterface object.

This example shows how to determine if an object is coder.descriptor.LookupTableDataInterface object.

Build a model

Open and build a model that contains lookup table blocks.

Return properties of Lookup Table parameter

Create a code descriptor object for the model.

codeDescObj = coder.getCodeDescriptor('ASAP2Demo');

Return properties of the Lookup Table parameter.

params = getDataInterfaces(codeDescObj,'Parameters');

The params variable is an array of coder.descriptor.DataInterface and coder.descriptor.LookupTableDataInterface objects. The model ASAP2Demo contains three Lookup Table blocks. Only two of them have tunable breakpoint set data. The code generator creates only two corresponding coder.descriptor.LookupTableDataInterface objects.

Obtain the details of the Standard_Axis block by accessing the sixth location in the array.

parameterObj = params(6);

Determine if the object stored in parameterObj variable is a coder.descriptor.LookupTableDataInterface object.

lookupTableDataInterface = isLookupTableDataInterface(parameterObj)
lookupTableDataInterface = logical

The code generator returns a logical value of 1 if parameterObj is a coder.descriptor.LookupTableDataInterface object. Otherwise, the code generator returns a logical value of 0.
