    • getCreationSQL

      public void getCreationSQL(SQLScript script)
      Description copied from class: PgStatement
      Generates the SQL statements needed to create this database object. This is an abstract method that must be implemented by subclasses to provide the specific CREATE SQL for each object type.
      Specified by:
      getCreationSQL in class PgStatement
      Parameters:
      script - the SQL script to append creation statements to

    • appendAlterSQL

      Fill script with object changes and return change type
      Specified by:
      appendAlterSQL in class PgStatement
      Parameters:
      newCondition - new object state
      script - script to collect changes

      object change type

    • compare

      public boolean compare(PgStatement obj)
      Description copied from class: PgStatement
      This method does not account for nested child PgStatements. Shallow version of PgStatement.equals(Object)
      Overrides:
      compare in class PgStatement

    • computeHash

      public void computeHash(Hasher hasher)
      Description copied from interface: IHashable
      Computes the hash of the implementing object using the provided hasher. The implementation should call appropriate put methods on the hasher for all fields that should contribute to the hash value.
      Specified by:
      computeHash in interface IHashable
      Parameters:
      hasher - the hasher instance to use for hash computation

      Description copied from class: PgStatement
      Copies all object properties into a new object and leaves all its children empty.
