    Syntax

    clear(testerObj)

    Description

    clear(testerObj) clears the workspace variables from the Simulink.data.adapters.AdapterDataTester object testerObj. The tester object provides functions for testing a custom external file adapter derived from the Simulink.data.adapters.BaseMatlabFileAdapter base class.

    example

    Examples

    Clear the workspace variables from a Simulink.data.adapters.AdapterDataTester object after using the object to test an XML file adapter derived from a Simulink.data.adapters.BaseMatlabFileAdapter base class. For an example of an XML file adapter, see Create External File Adapter for Loading Variables into Simulink.SimulationInput Object.

    The example uses an XML file test.xml with the following format.

    <customerData>
<x>10</x>
<y>15</y>
</customerData>

    Create an instance of your file adapter.

    adapterInstance = myXMLAdapter;

    Create an instance of the file adapter tester object using the test file specified above.

    adapterTester = Simulink.data.adapters.AdapterDataTester(adapterInstance,...
                                                         'test.xml','XML Adapter');

    Use adapterTester to read the data from your XML file. Then, check the data in the WorkspaceVariables property.

    readFromSource(adapterTester);
variables = adapterTester.WorkspaceVariables

    variables = 
  Map with properties:
    Count: 2
    KeyType: char
    ValueType: double

    Check the data in the WorkspaceVariables map object.

    variables.keys

    ans = 
  1x2 cell array
    {"x"}  {"y"}

    Finally, clear the workspace variables.

    clear(adapterTester);

    Input Arguments
