Constructor Detail

RouteSpecificPool

public RouteSpecificPool(HttpRoute route,
                 int maxEntries)

Deprecated. (4.1) use RouteSpecificPool(HttpRoute, ConnPerRoute)

RouteSpecificPool

public RouteSpecificPool(HttpRoute route,
                 ConnPerRoute connPerRoute)

Deprecated.

Creates a new route-specific pool.

Parameters:

route - the route for which to pool

connPerRoute - the connections per route configuration

Method Detail

getRoute

public final HttpRoute getRoute()

Deprecated.

Obtains the route for which this pool is specific.

Returns:

the route

getMaxEntries

public final int getMaxEntries()

Deprecated.

Obtains the maximum number of entries allowed for this pool.

Returns:

the max entry number

isUnused

public boolean isUnused()

Deprecated.

Indicates whether this pool is unused. A pool is unused if there is neither an entry nor a waiting thread. All entries count, not only the free but also the allocated ones.

Returns:

true if this pool is unused, false otherwise

getCapacity

public int getCapacity()

Deprecated.

Return remaining capacity of this pool

Returns:

capacity

getEntryCount

public final int getEntryCount()

Deprecated.

Obtains the number of entries. This includes not only the free entries, but also those that have been created and are currently issued to an application.

Returns:

the number of entries for the route of this pool

allocEntry

public BasicPoolEntry allocEntry(Object state)

Deprecated.

Obtains a free entry from this pool, if one is available.

Returns:

an available pool entry, or null if there is none

freeEntry

public void freeEntry(BasicPoolEntry entry)

Deprecated.

Returns an allocated entry to this pool.

Parameters:

entry - the entry obtained from allocEntry or presented to createdEntry

createdEntry

public void createdEntry(BasicPoolEntry entry)

Deprecated.

Indicates creation of an entry for this pool. The entry will not be added to the list of free entries, it is only recognized as belonging to this pool now. It can then be passed to freeEntry.

Parameters:

entry - the entry that was created for this pool

deleteEntry

public boolean deleteEntry(BasicPoolEntry entry)

Deprecated.

Deletes an entry from this pool. Only entries that are currently free in this pool can be deleted. Allocated entries can not be deleted.
