goSpace

Synopsis

goSpace, a pSpace implementation in Go.

Importing goSpace

To get goSpace, do:

go get -u github.com/pspaces/gospace

To import goSpace into your project, add:

import (
      . "github.com/pspaces/gospace"
)

goSpace API

The goSpace API follows the Space API Specification. It contains the following operations:

Put(x_1, x_2, ..., x_n)
PutP(x_1, x_2, ..., x_n)
Get(x_1, x_2, ..., x_n)
GetP(x_1, x_2, ..., x_n)
GetAll(x_1, x_2, ..., x_n)
Query(x_1, x_2, ..., x_n)
QueryP(x_1, x_2, ..., x_n)
QueryAll(x_1, x_2, ..., x_n)

A space can be created by using NewSpace for creating a local space, or NewRemoteSpace for connecting to a remote space.

To create a space on the localhost, one can do:

spc := NewSpace("space")

To connect to a remote space with name space, one can do:

spc := NewRemoteSpace("tcp://example.com/space")

All operations act on a Space structures and x_1, x_2, ..., x_n are terms in a tuple.

Operations such as Put, Get, and so forth are blocking operations.

Operations postfixed by a P such as PutP, GetP, and so forth are non-blocking operations.

For Put and PutP operations, the terms are values and for the remaining operations terms are either values or binding variables.

Pattern matching can be achieved by passing a binding variable, that is, passing a pointer to a variabe by adding an & infront of the variable.

Binding variables can only be passed to Get* and Query* operations.

The specification for the pSpace Space API can be found here.

Limitations

There are currently some limitations to the implementation:

• Only TCP over IPv4 is supported.
• Gates and space repositories are not supported yet.
• Multiplexing of multiple spaces over a single gate is not supported yet.

Examples

Examples and cases for goSpace can be found here.
