Column
implementation can provide its own text exchange format
for the given objects. This method enables the Column
to convert
a value of the given type to a String
array and via
Column.fromStorageStrings(String[])
back to the value (bijective).
This method supports data sinks (such as Amazon's SimpleDb) which provide
dedicated support for multiple values in a row's entry: In case T is an
array type, then the storage String
representations of the
elements in that array may be placed in dedicated entries of the returned
String
array. In case T is not an array type then the returned
String
array may contain just one value.
In case data sinks (such as relational databases) are to be addressed
which allow only a single value in a row's entry, then the method
Column.toStorageString(Object)
may be used instead.toStorageStrings
