Class StringBufferFactoryConstants

java.lang.Object

public class StringBufferFactoryConstants
extends java.lang.Object

StringBufferFactoryConstants specifies the size of the various StringBuffer buckets for the StringBufferFactory. Use this to change the profile of sizes of StringBuffers that the system manages. Note that it is important that the size specified be an ODD NUMBER. We use the 'plus 1' to detect if StringBuffers' capacity was expanded during use. Since StringBuffers capacity is doubled when expanded it will never be ODD again. Tune the PER_CAPACITY_POOL_SIZE and PER_CAPACITY_POOL_LIMIT to match up with your expected thread concurrency (simultaneous requests for StringBuffers) and desired memory footprint.
