store4 is a [Go](https://golang.org) package providing a fast in-memory quad store, with graph and subject views.
## Installation
```bash
go get github.com/jimsmart/store4
```
```go
import "github.com/jimsmart/store4"
```
### Dependencies
- Standard library.
- [Ginkgo](https://onsi.github.io/ginkgo/) and [Gomega](https://onsi.github.io/gomega/) if you wish to run the tests.
## Example
```go
import "github.com/jimsmart/store4"
s := store4.NewQuadStore()
s.Add("Alice", "knows", "Bob", "")
s.Add("Alice", "knows", "Charlie", "")
s.Add("Charlie", "knows", "Bob", "")
s.Add("Charlie", "age", 23, "")
// Find everyone that Alice knows, in any graph.
x := s.FindObjects("Alice", "knows", "*")
// Find everyone who knows Charlie, in the unnamed/default graph.
y := s.FindSubjects("knows", "Charlie", "")
// Iterate over all quads.
s.ForEach(func(s, p string, o interface{}, g string) {
// ...
})
// Iterate over quads matching given pattern.
s.ForEachWith("*", "*", "Bob", "*", func(s, p string, o interface{}, g string) {
// ...
})
// Remove all statements about Charlie, from all graphs.
s.Remove("Charlie", "*", "*", "*")
```
