Syntax

fileExtensions = getSupportedExtensions(adapterObj)


Description

fileExtensions = getSupportedExtensions(adapterObj) returns the file extensions that are supported by the file adapter.

Input Arguments

adapterObj — Custom file adapter

Simulink.data.adapters.BaseMatlabFileAdapter subclass object

Custom file adapter, specified as an object of a class that derives from the Simulink.data.adapters.BaseMatlabFileAdapter base class.

Example: myCustomFileAdapter

Examples

Get Supported File Extensions for Custom File Adapter

Write the function definition for the getSupportedExtensions method to return the list of supported file extensions for your custom adapter. Simulink^® uses this function to determine if the adapter can be used to load data from a particular external source file.

In this example, the getSupportedExtensions method for an XML file adapter returns only XML in its list of supported extensions.

function fileExtensions = getSupportedExtensions(adapterObj)
    fileExtensions = {'.XML'};
end
