Interface ClassLoaderLookupPolicy

@NoImplement
public interface ClassLoaderLookupPolicy

Defines which resources in a class loader should be looked up using parent-first, child-first or child only strategies.

Default lookup strategy is parent first. To use child-first, the corresponding package must be added as an overridden. To use child-only, the corresponding package must be added as blocked.

Method Summary

Modifier and Type	Method and Description
ClassLoaderLookupPolicy	extend(Map<String,LookupStrategy> lookupStrategies) Creates a new instance extending the original policy configuration.
ClassLoaderLookupPolicy	extend(Map<String,LookupStrategy> lookupStrategies, boolean overwrite) Creates a new instance extending the original policy configuration
LookupStrategy	getClassLookupStrategy(String className) Returns the lookup strategy to use for a given class.
LookupStrategy	getPackageLookupStrategy(String packageName) Returns the lookup strategy to use for a given package.

Method Detail

getClassLookupStrategy

LookupStrategy getClassLookupStrategy(String className)

Returns the lookup strategy to use for a given class.

Parameters:

className - class to lookup.

Returns:

the configured lookup strategy for the class's package or ChildFirstLookupStrategy.CHILD_FIRST if not explicit configuration was defined for the class's package.

getPackageLookupStrategy

LookupStrategy getPackageLookupStrategy(String packageName)

Returns the lookup strategy to use for a given package.

Parameters:

packageName - package to lookup.

Returns:

the configured lookup strategy for the class's package or ChildFirstLookupStrategy.CHILD_FIRST if not explicit configuration was defined for the package.

extend

ClassLoaderLookupPolicy extend(Map<String,LookupStrategy> lookupStrategies)

Creates a new instance extending the original policy configuration.

This is equivalent of calling extend(Map, boolean) with overwrite=false.

Parameters:

lookupStrategies - lookup strategies to use with specific packages. Non null.

Returns:

a new policy containing the lookup strategies from the original policy and the lookup strategies passed on the parameter.

extend

ClassLoaderLookupPolicy extend(Map<String,LookupStrategy> lookupStrategies,
                               boolean overwrite)

Creates a new instance extending the original policy configuration

Parameters:

lookupStrategies - lookup strategies to use with specific packages. Non null.

overwrite - if a lookupStrategy for a package provided in lookupStrategies already exists on this policy, it will be overridden or not depending on this value.

Returns:

a new policy containing the lookup strategies from the original policy and the lookup strategies passed on the parameter.
