A sequence in UNOIDL is an array containing a variable number of elements of the same UNOIDL type. The following is an example of a sequence term:
// this term could occur in a UNOIDL definition block somewhere sequence< com::sun::star::uno::XInterface >
It starts with the keyword sequence and gives the element type enclosed in angle brackets <>. The element type must be a known type. A sequence type can be used as parameter, return value, property or struct member just like any other type. Sequences can also be nested, if necessary.
// this could be a nested sequence definition sequence< sequence< long > > // this could be an operation using sequences in some interface definition sequence< string > getNamesOfIndex(sequence< long > indexes);
