Description

discardChanges(archDataObj) discards any changes made to the data dictionary archDataObj since the last time the data dictionary was saved.

Examples

Discard Changes to Simulink Data Dictionary

Add a new enumeration data type to the Architectural Data section of a data dictionary and then discard the changes.

Open the data dictionary MyInterfaces.sldd and use the isDirty function to verify that the data dictionary does not contain changes.

archDataObj = Simulink.dictionary.archdata.open("MyInterfaces.sldd");
isDirty(archDataObj)

ans =

  logical

   0

Add enumeration data type, MyEnum.

addEnumType(archDataObj,"MyEnum");
getDataTypeNames(archDataObj)

ans =

  1×8 cell array

  Columns 1 through 4

    {'MyEnum'}    {'myAliasType1'}    {'myAliasType2'}    {'myAliasType3'}

  Columns 5 through 8

    {'myColor'}    {'myStructType1'}    {'myStructType2'}    {'myValueType1'}

Discard the change.

discardChanges(archDataObj);
getDataTypeNames(archDataObj)

ans =

  1×7 cell array

  Columns 1 through 4

    {'myAliasType1'}    {'myAliasType2'}    {'myAliasType3'}    {'myColor'}
  Columns 5 through 7
    {'myStructType1'}    {'myStructType2'}    {'myValueType1'}
