Method Detail

lookup

public Object lookup(String name)

Description copied from interface: Scope

Lookups for bean name. It may happens that lookup is performed before the registration, therefore it should returns null if object is not yet registered.

Specified by:

lookup in interface Scope

register

public void register(String name,
                     Object bean)

Description copied from interface: Scope

Registers the bean within the current scope.

Specified by:

register in interface Scope

remove

public void remove(String name)

Description copied from interface: Scope

Removes the bean from the scope entirely.

Specified by:

remove in interface Scope

accept

public boolean accept(Scope referenceScope)

Description copied from interface: Scope

Returns true if a bean of referenced scope can be injected into target bean of this scope. Otherwise, returns false, which may be a sign for scoped proxy to be injected.

In general, injection of 'shorter' reference scopes into the 'longer' target scopes should not be accepted. In other words, if reference scope is 'longer' or equal (same), this method should return true.

Specified by:

accept in interface Scope

getHttpSessionId

protected String getHttpSessionId()

Returns request from current thread.
