Tape is a collection of queue-related classes for Android and Java.
QueueFile
is a lightning-fast, transactional, file-based FIFO. Addition and
removal from an instance is an O(1) operation and is atomic. Writes are
synchronous; data will be written to disk before an operation returns. The
underlying file is structured to survive process and even system crashes and if
an I/O exception is thrown during a mutating change, the change is aborted.
An ObjectQueue
represents an ordering of arbitrary objects which can be backed
either by the filesystem (via QueueFile
) or in memory only.
TaskQueue
is a special object queue which holds Task
s, objects which have a
notion of being executed. Instances are managed by an external executor which
prepares and executes enqueued tasks.
Some examples are available on the website.
Downloadable .jars can be found on the GitHub download page.
