  • Field Details

    • STANDARD

      public static final TypeMapper STANDARD
      TypeMapper implementation which performs generally useful conversions. In particular, Date subclasses (including java.sql.Date, java.sql.Time and java.sql.Timestamp are turned into Strings, using JDBC timestamp escape format (which is ISO-8601 with a space character separating date and time). The intention is that by using this implementation you will get an output table which can be written using non-specialist output formats such as FITS and VOTable.
    • DALI

      public static final TypeMapper DALI
      TypeMapper implementation like STANDARD, but which uses a 'T' character as the separator between the date and time parts of timestamp serializations. Use of the 'T' separator is mandated by the Data Access Layer Interface standard v1.0, section 3.1.2 (http://www.ivoa.net/documents/DALI/), and so is appropriate for output from VO services such as TAP.
    • IDENTITY

      public static final TypeMapper IDENTITY
      TypeMapper implementation which performs no conversions. The output types are just as JDBC provides them.
  • Method Details

    • createIdentityValueHandler

      public static ValueHandler createIdentityValueHandler(ResultSetMetaData meta, int jcol1) throws SQLException
      Constructs a new ValueHandler which performs no conversions.
      Parameters:
      meta - JDBC metadata object
      jcol1 - JDBC column index (first column is 1)
      Throws:
      SQLException
    • createStringValueHandler

      public static ValueHandler createStringValueHandler(ResultSetMetaData meta, int jcol1) throws SQLException
      Constructs a new ValueHandler which converts values to Strings.
      Parameters:
      meta - JDBC metadata object
      jcol1 - JDBC column index (first column is 1)
      Throws:
      SQLException
    • createTimestampValueHandler

      public static ValueHandler createTimestampValueHandler(ResultSetMetaData meta, int jcol1, char dateTimeSeparator) throws SQLException
      Constructs a new ValueHandler which converts JDBC Timestamp values to Strings, with a configurable date/time separator character. The input values are assumed to be of type Timestamp.
      Parameters:
      meta - JDBC metadata object
      jcol1 - JDBC column index (first column is 1)
      dateTimeSeparator - separator character between date and time parts of ISO-8601 string; usually either ' ' or 'T'
      Throws:
      SQLException
