Method Detail

setOrder

public void setOrder(int order)

getOrder

public int getOrder()

Description copied from interface: Ordered

Return the order value of this object, with a higher value meaning greater in terms of sorting.

Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE indicating greatest. Same order values will result in arbitrary positions for the affected objects.

Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).

Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.

Specified by:: getOrder in interface Ordered

Returns:: the order value
See Also:: Ordered.LOWEST_PRECEDENCE

isPerInstance

public boolean isPerInstance()

Description copied from interface: Advisor

Return whether this advice is associated with a particular instance (for example, creating a mixin) or shared with all instances of the advised class obtained from the same Spring bean factory.

Note that this method is not currently used by the framework. Typical Advisor implementations always return true. Use singleton/prototype bean definitions or appropriate programmatic proxy creation to ensure that Advisors have the correct lifecycle model.

Specified by:: isPerInstance in interface Advisor

Returns:: whether this advice is associated with a particular target instance

equals

public boolean equals(Object other)

Overrides:: equals in class Object

hashCode

public int hashCode()

Overrides:: hashCode in class Object
