RecyclerPool.ConcurrentDequePoolBase (jackson-core 2.17.0)

java.lang.Object
- com.fasterxml.jackson.core.util.RecyclerPool.StatefulImplBase<P>
- - com.fasterxml.jackson.core.util.RecyclerPool.ConcurrentDequePoolBase<P>

All Implemented Interfaces:

RecyclerPool<P>, Serializable

Direct Known Subclasses:

JsonRecyclerPools.ConcurrentDequePool

Enclosing interface:

RecyclerPool<P extends RecyclerPool.WithPool<P>>
```
public abstract static class RecyclerPool.ConcurrentDequePoolBase<P extends RecyclerPool.WithPool<P>>
extends RecyclerPool.StatefulImplBase<P>
```
RecyclerPool implementation that uses ConcurrentLinkedDeque for recycling instances.
Pool is unbounded: see RecyclerPool what this means.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`P`	`acquirePooled()` Method for sub-classes to implement for actual acquire logic; called by `RecyclerPool.acquireAndLinkPooled()`.
`boolean`	`clear()` Optional method that may allow dropping of all pooled Objects; mostly useful for unbounded pool implementations that may retain significant memory and that may then be cleared regularly.
`void`	`releasePooled(P pooled)` Method that should be called when previously acquired (see `RecyclerPool.acquireAndLinkPooled()`) pooled value that is no longer needed; this lets pool to take ownership for possible reuse.

```
public P acquirePooled()

    Description copied from interface: RecyclerPool
    
    Method for sub-classes to implement for actual acquire logic; called by RecyclerPool.acquireAndLinkPooled().
    
    Returns:
    
    Instance acquired (pooled or just constructed)
  - releasePooled
```
public void releasePooled(P pooled)
```
    Description copied from interface: RecyclerPool
    
    Method that should be called when previously acquired (see RecyclerPool.acquireAndLinkPooled()) pooled value that is no longer needed; this lets pool to take ownership for possible reuse.
    
    Parameters:
    
    pooled - Pooled instance to release back to pool
  - clear
```
public boolean clear()
```
    Description copied from interface: RecyclerPool
    
    Optional method that may allow dropping of all pooled Objects; mostly useful for unbounded pool implementations that may retain significant memory and that may then be cleared regularly.
    
    Returns:
    
    true If pool supports operation and dropped all pooled Objects; false otherwise.
