Constructor Detail

ResourceOracleImpl

public ResourceOracleImpl(List<ClassPathEntry> classPath)

Constructs a ResourceOracleImpl from a set of ClassPathEntries. The list is held by reference and must not be modified.

ResourceOracleImpl

public ResourceOracleImpl(TreeLogger logger)

Constructs a ResourceOracleImpl from the thread's default ClassLoader.

ResourceOracleImpl

public ResourceOracleImpl(TreeLogger logger,
                          ClassLoader classLoader)

Constructs a ResourceOracleImpl from a ClassLoader. The specified ClassLoader and all of its parents which are instances of URLClassLoader will have their class path entries added to this instances underlying class path.

ResourceOracleImpl

public ResourceOracleImpl(TreeLogger logger,
                          ResourceLoader resources)

Method Detail

clearCache

public static void clearCache()

createEntryForUrl

public static ClassPathEntry createEntryForUrl(TreeLogger logger,
                                               URL url)
                                        throws URISyntaxException,
                                               IOException

Throws:

URISyntaxException

IOException

preload

public static void preload(TreeLogger logger)

Preinitializes the classpath from the thread default ClassLoader.

preload

public static void preload(TreeLogger logger,
                           ClassLoader classLoader)

Preinitializes the classpath for a given ClassLoader.

preload

public static void preload(TreeLogger logger,
                           ResourceLoader resources)

Preinitializes the classpath for a given ResourceLoader.

refresh

public static void refresh(TreeLogger logger,
                           ResourceOracleImpl first,
                           ResourceOracleImpl... rest)

Rescans the associated paths to recompute the available resources. TODO(conroy,scottb): This synchronization could be improved upon to allow disjoint sets of oracles to be refreshed simultaneously.

Parameters:

logger - status and error details are written here

first - At least one ResourceOracleImpl must be passed to refresh

rest - Callers may optionally pass several oracles

clear

public void clear()

Description copied from interface: ResourceOracle

Frees up all existing resources and transient internal state. All returned collections will be empty after this call until this ResourceOracle is refreshed.

Specified by:

clear in interface ResourceOracle

getPathNames

public Set<String> getPathNames()

Description copied from interface: ResourceOracle

Returns an unmodifiable set of unique abstract path names with constant lookup time.

Specified by:

getPathNames in interface ResourceOracle

getPathPrefixes

public PathPrefixSet getPathPrefixes()

getResourceMap

public Map<String,Resource> getResourceMap()

Description copied from interface: ResourceOracle

Returns an unmodifiable map of abstract path name to resource.

Specified by:

getResourceMap in interface ResourceOracle

getResources

public Set<Resource> getResources()

Description copied from interface: ResourceOracle

Returns an unmodifiable set of unique resources with constant lookup time.

Specified by:

getResources in interface ResourceOracle

setPathPrefixes

public void setPathPrefixes(PathPrefixSet pathPrefixSet)
