Method Detail

getRequestMap

protected java.util.Map<java.lang.String,jodd.petite.scope.RequestScope.TransientBeanData> getRequestMap(javax.servlet.http.HttpServletRequest servletRequest)

Returns instance map from http request.

removeRequestMap

protected void removeRequestMap(javax.servlet.http.HttpServletRequest servletRequest)

Removes instance map from the request.

createRequestMap

protected java.util.Map<java.lang.String,jodd.petite.scope.RequestScope.TransientBeanData> createRequestMap(javax.servlet.http.HttpServletRequest servletRequest)

shutdown

public void shutdown()

Description copied from interface: Scope

Shutdowns the scope by removing all beans and calling destroy methods.

Specified by:

shutdown in interface Scope

lookup

public java.lang.Object lookup(java.lang.String name)

Description copied from interface: Scope

Lookups for bean name. Returns null if bean is not found or yet registered.

Specified by:

lookup in interface Scope

register

public void register(BeanDefinition beanDefinition,
                     java.lang.Object bean)

Description copied from interface: Scope

Registers the bean within the current scope. Usually registers it by its name from BeanDefinition. Also it may register destroy methods of a bean within this scope.

Specified by:

register in interface Scope

remove

public void remove(java.lang.String name)

Description copied from interface: Scope

Removes the bean from the scope entirely. Destroy methods are not called as it is assumed that bean is destroyed manually.

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.

Helpful is to ask the following question: "May the reference scope bean be injected into bean of this scope?".

Specified by:

accept in interface Scope

getCurrentHttpRequest

protected javax.servlet.http.HttpServletRequest getCurrentHttpRequest()

Returns request from current thread.
