Methods

Modifier and Type	Method and Description
<T> List<T>	create(Class<T> spi) Creates instances of extensions listed under META-INF/services/ fully-qualified-SPI-name ; implementations must have a public no-arg constructor.
<T,C> List<T>	create(Class<T> spi, Class<C> contextType, C context) Creates instances of extensions listed under META-INF/services/ fully-qualified-SPI-name ; implementations must either have a public no-arg constructor or one with the declared context type.
static SisuExtensions	global(ClassSpace space) Returns global SisuExtensions from the surrounding class space.
void	install(com.google.inject.Binder binder) Installs modules listed under META-INF/services/com.google.inject.Module; modules must have a public no-arg constructor.
<C> void	install(com.google.inject.Binder binder, Class<C> contextType, C context) Installs modules listed under META-INF/services/com.google.inject.Module; modules must either have a public no-arg constructor or one with the declared context type.
<T> List<Class<? extends T>>	load(Class<T> spi) Loads extension types listed under META-INF/services/ fully-qualified-SPI-name.
static SisuExtensions	local(ClassSpace space) Returns local SisuExtensions from the containing class space.
SpaceVisitor	visitor(com.google.inject.Binder binder) SpaceModule strategy that lets META-INF/services/org.eclipse.sisu.space.SpaceVisitor extensions override the default scanning.
Wiring	wiring(com.google.inject.Binder binder) WireModule strategy that lets META-INF/services/org.eclipse.sisu.wire.Wiring extensions override the default wiring.
