The Read and Write in a Space

The Get and Take operations are used to read from a space. The Put operations is used to write to a space.

• Getting or Taking a Single Tuple from the Space
  Retrieving or taking a single tuple from a space is done using the space’s get or take methods.
• Put Operation for Storing a Tuple in a Space
  To store a tuple in a space, call the space’s put method, which takes the tuple to put as an argument and returns what ever was overwritten in the space (if anything was) by the put.
• Operations on a Tuple in a Space
  Put operations always overwrite (and return) whatever was stored before them in the space. But when more than one application updates the same data concurrently, it can be necessary to use “compare and set” type operations.
