Class ThreadSafeFormat

java.lang.Object
  org.compass.core.converter.basic.format.ThreadSafeFormat

All Implemented Interfaces:

Formatter

public class ThreadSafeFormat
extends Object
implements Formatter

Wrapper around Formatter that can be called by multiple threads concurrently.

Format has a high overhead in creating and is not thread safe. To make best use of resources, the ThreadSafeFormat provides a dynamically sizing pool of instances, each of which will only be called by a single thread at a time.

The pool has a maximum capacity, to limit overhead. If all instances in the pool are in use and another is required, it shall block until one becomes available.
