valueOf

public java.lang.Object valueOf(java.lang.String s)

Description copied from interface: TypeHandlerCallback

Casts the string representation of a value into a type recognized by this type handler. This method is used to translate nullValue values into types that can be appropriately compared. If your custom type handler cannot support nullValues, or if there is no reasonable string representation for this type (e.g. File type), you can simply return the String representation as it was passed in. It is not recommended to return null, unless null was passed in.

Specified by:

valueOf in interface TypeHandlerCallback

Parameters:

s - A string representation of a valid value for this type.

Returns:

One of the following:

1. the casted repersentation of the String value,
2. the string as is,
3. null, only if null was passed in.
