Detailed Description

<<interface>> <<generic>> A type-safe, ordered collection of elements. The type of these elements is referred to in this documentation as Foo.

For users who define data types in OMG IDL, this type corresponds to the IDL express sequence<Foo>.

For any user-data type Foo that an application defines for the purpose of data-distribution with RTI Connext, a FooSeq is generated. We refer to an IDL sequence<Foo> as FooSeq.

A sequence is a type-safe List that makes a distinction between its allocated size and its logical size (much like the ArrayList class). The Collection.size() method returns the logical size.

A new sequence is created for elements of a particular Class, which does not change throughout the lifetime of a sequence instance.

To add an element to a sequence, use the add() method inherited from the standard interface java.util.List; this will implicitly increase the sequence's size. Or, to pre-allocate space for several elements at once, use Sequence.setMaximum.

An attempt to add an element to a sequence that is not of the correct element type will result in a ClassCastException. (Note that null is considered to belong to any type.)
