      public CreateJsonIndexGenerator()

  • Method Details

    • getPriority

      public int getPriority()
      Override the priority. This is needed because CreateJsonIndexStatement is a subtype of CreateIndexStatement and is thus a match for the standard index generators. By increasing the priority we ensure this is processed before the other generators.
      Specified by:
      getPriority in interface liquibase.servicelocator.PrioritizedService
      Specified by:
      getPriority in interface liquibase.sqlgenerator.SqlGenerator<CreateJsonIndexStatement>
      Overrides:
      getPriority in class liquibase.sqlgenerator.core.AbstractSqlGenerator<CreateJsonIndexStatement>
      Returns:
      this generator's priority.
