ProcessContainer class

Inversion of control (IoC) container that runs as a system process. It processes command line arguments and handles unhandled exceptions and Ctrl-C signal to gracefully shutdown the container.

Command line arguments

  • --config / -c path to JSON or YAML file with container configuration (default: './config/config.yml')
  • --param / --params / -p value(s) to parameterize the container configuration
  • --help / -h prints the container usage help

Methods

addFactory(IFactory factory) → void
Adds a factory to the container. The factory is used to create components added to the container by their locators (descriptors).
inherited
close(String? correlationId) → Future
Closes component and frees used resources.
inherited
configure(ConfigParams config) → void
Configures component by passing configuration parameters.
inherited
isOpen() → bool
Checks if the component is opened.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
open(String? correlationId) → Future
Opens the component.
inherited
readConfigFromFile(String? correlationId, String path, ConfigParams parameters) → Future
Reads container configuration from JSON or YAML file and parameterizes it with given values.
inherited
run(List<String> args) → void
Runs the container by instantiating and running components inside the container.
setReferences(IReferences references) → void
Sets references to dependent components.
inherited
toString() → String
A string representation of this object.
inherited
unsetReferences() → void
Unsets (clears) previously set references to dependent components.
