Class ByteArrayVariableValidator

java.lang.Object
io.camunda.migrator.impl.interceptor.ByteArrayVariableValidator
All Implemented Interfaces:
VariableInterceptor
@Order(1) @Component public class ByteArrayVariableValidator extends Object implements VariableInterceptor
Validator for byte array variables during migration from Camunda 7 to Camunda 8.

Validates that primitive variables do not contain byte arrays, which are unsupported in C8. This interceptor runs first to catch byte arrays before any other processing. Can be disabled via the configuration file using the enabled property.

    • getTypes

      public Set<Class<?>> getTypes()
      Description copied from interface: VariableInterceptor
      Returns the set of variable value types that this interceptor can handle.

      Use Camunda's existing type interfaces like: - PrimitiveValue.class for primitive variables - DateValue.class for date variables - ObjectValue.class for object variables (JSON, XML, Java serialized) - FileValue.class for file variables - SpinValue.class for Spin variables

      If the returned set is empty, this interceptor will be called for all variable types.

      Default implementation returns an empty set (handle all types) for backward compatibility.

      Specified by:
      getTypes in interface VariableInterceptor
      Returns:
      set of supported variable value types, or empty set to handle all types

    • execute

      public void execute(VariableInvocation invocation)
      Description copied from interface: VariableInterceptor
      Executes the interceptor logic for a variable invocation. This method will only be called if the variable type matches one of the supported types.
      Specified by:
      execute in interface VariableInterceptor
      Parameters:
      invocation - the variable invocation containing C7 variable data and methods to modify it
