canContainKeyMethodMapArray

private static final Method[] canContainKeyMethodMapArray

In order to determine if a given lease will be accepted by this map as a "legal" key value, the method canContainKey must verify that the corresponding methods of the initial lease used to create this map and the lease input to canContainKey have equivalent constraints. The array defined here contains the set of methods whose constraints will be compared in canContainKey.

methodConstraints

private MethodConstraints methodConstraints

Client constraints placed on this proxy (may be null).

Constructor Detail

FiddlerLeaseMap.ConstrainableFiddlerLeaseMap

private FiddlerLeaseMap.ConstrainableFiddlerLeaseMap(Fiddler server,
                                            FiddlerLease lease,
                                            long duration,
                                            MethodConstraints methodConstraints)

Constructs a new ConstrainableFiddlerLeaseMap instance.

For a description of all but the methodConstraints argument (provided below), refer to the description for the constructor of this class' super class.

Parameters:

methodConstraints - the client method constraints to place on this proxy (may be null).

Method Detail

canContainKey

public boolean canContainKey(Object key)

Examines the input parameter to determine if that parameter will be accepted or rejected by this map as a "legal" key value.

This method will return true if the key parameter is the type of lease which can be "batch-wise" renewed and cancelled along with all of the other leases in the map.

For this implementation of the service, two leases can be batched (placed in the same service-specific instance of LeaseMap) if those leases satisfy the following conditions:

• the leases are the same type; that is, the leases are both instances of the same, constrainable, service-specific Lease implementation
• the leases were granted by the same backend server
• the leases have the same constraints

Specified by:

canContainKey in interface LeaseMap

Overrides:

canContainKey in class FiddlerLeaseMap

Parameters:

key - reference to the object that this method examines to determine if this map will accept or reject it as a key

Returns:

true if this map will accept the key parameter, false otherwise

constrainServer

private static Fiddler constrainServer(Fiddler server,
                      MethodConstraints constraints)

Returns a copy of the given server proxy having the client method constraints that result after the specified method mapping is applied to the given client method constraints.
