Discard Changes to Simulink Interface Dictionary

Add a new enumeration type to an interface dictionary and then discard the changes.

Verify that the dictionary does not contain changes.

dictAPI = Simulink.interface.dictionary.open('MyInterfaces.sldd');
isDirty(dictAPI)

ans =
  logical
   0

Add enumeration type, MyEnum.

addEnumType(dictAPI,'MyEnum');
getDataTypeNames(dictAPI)

ans =
  1×8 cell array
  Columns 1 through 5
    {'MyEnum'}    {'myAliasType1'}    {'myAliasType2'}    {'myAliasType3'}    {'myColor'}
  Columns 6 through 8
    {'myStructType1'}    {'myStructType2'}    {'myValueType1'}

Discard the change.

discardChanges(dictAPI);
getDataTypeNames(dictAPI)

ans =
  1×7 cell array
  Columns 1 through 4
    {'myAliasType1'}    {'myAliasType2'}    {'myAliasType3'}    {'myColor'}
  Columns 5 through 7
    {'myStructType1'}    {'myStructType2'}    {'myValueType1'}
