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.

accept in interface Scope

getHttpSessionId

protected java.lang.String getHttpSessionId()
