Class ByteBufferPool<T extends ByteBufferPool<T>>

java.lang.Object

org.wildfly.swarm.config.undertow.ByteBufferPool<T>

public class ByteBufferPool<T extends ByteBufferPool<T>>
extends Object

A byte buffer pool used for IO operations, this provides the same capabilities as the buffer pool from the IO subsystem, so they can be used interchangeably and must have a unique name. This buffer pool allows for more precise configuration of the total amount of retained memory than the IO subsystem.

Method Detail

getKey

public String getKey()

addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a property change listener

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a property change listener

bufferSize

public Integer bufferSize()

The size of the buffer

bufferSize

public T bufferSize(Integer value)

The size of the buffer

direct

public Boolean direct()

If this is true the buffer pool will use direct buffers, this is recommended for best performance

direct

public T direct(Boolean value)

If this is true the buffer pool will use direct buffers, this is recommended for best performance

leakDetectionPercent

public Integer leakDetectionPercent()

The percentage of buffers that will be allocated with a leak detector. This should only be larger than zero if you are experiencing issues with buffers leaking.

leakDetectionPercent

public T leakDetectionPercent(Integer value)

The percentage of buffers that will be allocated with a leak detector. This should only be larger than zero if you are experiencing issues with buffers leaking.

maxPoolSize

public Integer maxPoolSize()

The maximum amount of buffers to keep in the pool. If more buffers are required at runtime they will be allocated dynamically. Setting this to zero effectively disables pooling.

maxPoolSize

public T maxPoolSize(Integer value)

The maximum amount of buffers to keep in the pool. If more buffers are required at runtime they will be allocated dynamically. Setting this to zero effectively disables pooling.

threadLocalCacheSize

public Integer threadLocalCacheSize()

The maximum number of buffers to cache on each thread. The actual number may be lower depending on the calculated usage pattern.

threadLocalCacheSize

public T threadLocalCacheSize(Integer value)

The maximum number of buffers to cache on each thread. The actual number may be lower depending on the calculated usage pattern.
