  • Method Details

    • getDefaultArrayTypeOid

      int getDefaultArrayTypeOid()
      The default array type oid supported by this instance.
      Returns:
      The default array type oid supported by this instance.

    • toArrayString

      String toArrayString(char delim, A array)
      Creates String representation of the array.
      Parameters:
      delim - The character to use to delimit between elements.
      array - The array to represent as a String.
      Returns:
      String representation of the array.

    • supportBinaryRepresentation

      boolean supportBinaryRepresentation(int oid)
      Indicates if an array can be encoded in binary form to array oid.
      Parameters:
      oid - The array oid to see check for binary support.
      Returns:
      Indication of whether toBinaryRepresentation(BaseConnection, Object, int) is supported for oid.

    • toBinaryRepresentation

      byte[] toBinaryRepresentation(BaseConnection connection, A array, int oid) throws SQLException, SQLFeatureNotSupportedException
      Creates binary representation of the array.
      Parameters:
      connection - The connection the binary representation will be used on. Attributes from the connection might impact how values are translated to binary.
      array - The array to binary encode. Must not be null, but may contain null elements.
      oid - The array type oid to use. Calls to supportBinaryRepresentation(int) must have returned true.
      Returns:
      The binary representation of array.
      Throws:
      SQLFeatureNotSupportedException - If supportBinaryRepresentation(int) is false for oid.
      SQLException

    • appendArray

      void appendArray(StringBuilder sb, char delim, A array)
      Append String representation of array to sb.
      Parameters:
      sb - The StringBuilder to append to.
      delim - The delimiter between elements.
      array - The array to represent. Will not be null, but may contain null elements.
