Container

Central container for managing dependencies and performing dependency injection.

Mote: Container use Caster for get dependencies by type.

Create New Container

import "github.com/bopher/container";
cnt := container.NewContainer();

Usage

Container interface contains following methods:

Register

Add new dependency to container

// Signature:
Register(name string, dep any)

// Example:
cnt.Register("app-name", "My App")

Resolve

Get dependency. this function return false as second return value if dependency not exists.

Caution: Resolve return data as any type. if you need to parse data as special type use helper parser methods described later.

// Signature:
Resolve(name string) (any, bool)

// Example:
appName, exists := cnt.Resolve("app-name") // => "My App", true

Exists

Check if dependency exists.

// Signature:
Exists(name string) bool

// Example:
exists := cnt.Exists("app-name") // => true

Cast

Parse dependency as caster.

// Signature:
Cast(name string) caster.Caster

// Example:
v, err := cnt.Cast("timeout").Int()
