X
- The conversion type.- Parameters:
value
- The value to unwraptype
- The type as which to unwrapoptions
- The options- Returns:
- The unwrapped value.
-
wrap

ResultSet
extraction.- Specified by:
wrap
in interfaceJavaType<C extends Collection<E>>
- Type Parameters:
X
- The conversion type.- Parameters:
value
- The value to wrap.options
