  - ### Method Detail

    - #### values

          public static DatabaseParameterBufferImp.DpbMetaData[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (DatabaseParameterBufferImp.DpbMetaData c : DatabaseParameterBufferImp.DpbMetaData.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static DatabaseParameterBufferImp.DpbMetaData valueOf​(java.lang.String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
        `name` - the name of the enum constant to be returned.
      Returns:
        the enum constant with the specified name
      Throws:
        `java.lang.IllegalArgumentException` - if this enum type has no constant with the specified name
        `java.lang.NullPointerException` - if the argument is null

    - #### getType

          public final int getType()

      Description copied from interface: `ParameterBufferMetaData`
      Parameter buffer type (this usually is the version of the parameter buffer).
      Specified by:
        `getType` in interface `ParameterBufferMetaData`
      Returns:
        Buffer type (for example `ISCConstants.isc_spb_version3`).

    - #### addPreamble

          public final void addPreamble​(ParameterBuffer parameterBuffer)

      Description copied from interface: `ParameterBufferMetaData`
      Allows the metadata to add a preamble to the parameter buffer.

      This is only intended for the weird "version 2" connection service parameter buffer that requires two tags for the version with `isc_spb_version, isc_spb_current_version`.

      Specified by:
        `addPreamble` in interface `ParameterBufferMetaData`
      Parameters:
        `parameterBuffer` - Parameter buffer.

    - #### getStringArgumentType

          public final ArgumentType getStringArgumentType​(int tag)

      Description copied from interface: `ParameterBufferMetaData`
      Gets the string argument type for the supplied tag.

      When the tag is not known (or unsupported for string arguments), then the default should be returned.

      Specified by:
        `getStringArgumentType` in interface `ParameterBufferMetaData`
      Parameters:
        `tag` - Tag (item type)
      Returns:
        Argument type (never `null`)

    - #### getByteArrayArgumentType

          public final ArgumentType getByteArrayArgumentType​(int tag)

      Description copied from interface: `ParameterBufferMetaData`
      Gets the byte array argument type for the supplied tag.

      When the tag is not known (or unsupported for string arguments), then the default should be returned.

      Specified by:
        `getByteArrayArgumentType` in interface `ParameterBufferMetaData`
      Parameters:
        `tag` - Tag (item type)
      Returns:
        Argument type (never `null`)

    - #### getIntegerArgumentType

          public final ArgumentType getIntegerArgumentType​(int tag)

      Description copied from interface: `ParameterBufferMetaData`
      Gets the byte array argument type for the supplied tag.

      When the tag is not known (or unsupported for string arguments), then the default should be returned.

      Specified by:
        `getIntegerArgumentType` in interface `ParameterBufferMetaData`
      Parameters:
        `tag` - Tag (item type)
      Returns:
        Argument type (never `null`)
