Method Summary

Modifier and Type	Method and Description
public int	Returns: the number of acquired connections acquiredSize() Measure the current number of connections that have been successfully `ConnectionPool#create()` acquired} and are in active use.
public int	Returns: the total number of allocated connections managed by the `Pool` allocatedSize() Measure the current number of allocated connections in the `ConnectionPool`, acquired or idle.
public int	Returns: the maximum number of live connections that can be allocated by the `ConnectionPool`. getMaxAllocatedSize() Get the maximum number of live connections this `ConnectionPool` will allow.
public int	Returns: the maximum number of pending acquire that can be enqueued by the `ConnectionPool`. getMaxPendingAcquireSize() Get the maximum number of `ConnectionPool#create()` this `ConnectionPool` can queue in a pending state when no available connection is immediately handy (and the `ConnectionPool` cannot allocate more connections).
public int	Returns: the number of idle connections idleSize() Measure the current number of idle connections in the `ConnectionPool`.
public int	Returns: the number of pending acquire pendingAcquireSize() Measure the current number of "pending" `ConnectionPool#create()` acquire Monos in the `ConnectionPool`.

Method Detail

acquiredSize back to summary

acquiredSize	back to summary
public int acquiredSize() Measure the current number of connections that have been successfully `ConnectionPool#create()` acquired} and are in active use. Returns:int the number of acquired connections

public int acquiredSize()

Measure the current number of connections that have been successfully ConnectionPool#create() acquired} and are in active use.

Returns:int: the number of acquired connections

allocatedSize back to summary

allocatedSize	back to summary
public int allocatedSize() Measure the current number of allocated connections in the `ConnectionPool`, acquired or idle. Returns:int the total number of allocated connections managed by the `Pool`

public int allocatedSize()

Measure the current number of allocated connections in the ConnectionPool, acquired or idle.

Returns:int: the total number of allocated connections managed by the Pool

getMaxAllocatedSize back to summary

getMaxAllocatedSize	back to summary
public int getMaxAllocatedSize() Get the maximum number of live connections this `ConnectionPool` will allow. A `ConnectionPool` might be unbounded, in which case this method returns `Integer#MAX_VALUE`. Returns:int the maximum number of live connections that can be allocated by the `ConnectionPool`.

public int getMaxAllocatedSize()

Get the maximum number of live connections this ConnectionPool will allow.

A ConnectionPool might be unbounded, in which case this method returns Integer#MAX_VALUE.

Returns:int: the maximum number of live connections that can be allocated by the ConnectionPool.

getMaxPendingAcquireSize back to summary

getMaxPendingAcquireSize	back to summary
public int getMaxPendingAcquireSize() Get the maximum number of `ConnectionPool#create()` this `ConnectionPool` can queue in a pending state when no available connection is immediately handy (and the `ConnectionPool` cannot allocate more connections). A `ConnectionPool` pending queue might be unbounded, in which case this method returns `Integer#MAX_VALUE`. Returns:int the maximum number of pending acquire that can be enqueued by the `ConnectionPool`.

public int getMaxPendingAcquireSize()

Get the maximum number of ConnectionPool#create() this ConnectionPool can queue in a pending state when no available connection is immediately handy (and the ConnectionPool cannot allocate more connections).

A ConnectionPool pending queue might be unbounded, in which case this method returns Integer#MAX_VALUE.

Returns:int: the maximum number of pending acquire that can be enqueued by the ConnectionPool.

idleSize back to summary

idleSize	back to summary
public int idleSize() Measure the current number of idle connections in the `ConnectionPool`. Note that some connections might be lazily evicted when they're next considered for an incoming `ConnectionPool#create()` call. Such connections would still count towards this method. Returns:int the number of idle connections

public int idleSize()

Measure the current number of idle connections in the ConnectionPool.

Note that some connections might be lazily evicted when they're next considered for an incoming ConnectionPool#create() call. Such connections would still count towards this method.

Returns:int: the number of idle connections

pendingAcquireSize back to summary

pendingAcquireSize	back to summary
public int pendingAcquireSize() Measure the current number of "pending" `ConnectionPool#create()` acquire Monos in the `ConnectionPool`. An acquire is in the pending state when it is attempted at a point when no idle connections is available in the pool, and no new connection can be created. Returns:int the number of pending acquire

public int pendingAcquireSize()

Measure the current number of "pending" ConnectionPool#create() acquire Monos in the ConnectionPool.

An acquire is in the pending state when it is attempted at a point when no idle connections is available in the pool, and no new connection can be created.

Returns:int: the number of pending acquire
