Field Detail

logger

protected final org.jboss.logging.Logger logger

generatedClasses

protected final ConcurrentHashMap<String,String> generatedClasses

Classnames of classes that will be created - we do not want to look for these in other pools. The main use for this is when a class is created in a parent pool, and we then want to create a class with the same name in a parent-last child pool. As part of the create process javassist.ClassPool will check if that class is frozen (which in turn will call getCached() and get0()). If the classname exists in this map, get0() and getCached() should return null;

localResources

protected final ConcurrentHashMap<String,Boolean> localResources

loadedButNotWovenClasses

protected final ConcurrentHashMap<String,Boolean> loadedButNotWovenClasses

Classnames of classes that have been loaded, but were not woven

SEARCH_ALL_STRATEGY

public static final Class<org.jboss.classpool.spi.AbstractClassPool.SearchAllRegisteredLoadersSearchStrategy> SEARCH_ALL_STRATEGY

Causes the AbstractClassPool.getCached() method to search all ClassPools registered in the repository

SEARCH_LOCAL_ONLY_STRATEGY

public static final Class<org.jboss.classpool.spi.AbstractClassPool.SearchLocalLoaderLoaderSearchStrategy> SEARCH_LOCAL_ONLY_STRATEGY

Causes the AbstractClassPool.getCached() method to search only itself
