  org.apache.camel.impl.converter.CorePackageScanClassResolver

All Implemented Interfaces:

PackageScanClassResolver

public class CorePackageScanClassResolver
extends Object
implements PackageScanClassResolver

A ClassResolver which loads type converters from a hardcoded list of classes.

Important: Whenever a new type converter class is added to camel-core then the class should be added to the list in this class.

Method Detail

setClassLoaders

public void setClassLoaders(Set<ClassLoader> classLoaders)

Description copied from interface: PackageScanClassResolver

Sets the ClassLoader instances that should be used when scanning for classes. If none is set then the context classloader will be used.

Specified by:

setClassLoaders in interface PackageScanClassResolver

Parameters:

classLoaders - loaders to use when scanning for classes

getClassLoaders

public Set<ClassLoader> getClassLoaders()

Description copied from interface: PackageScanClassResolver

Gets the ClassLoader instances that should be used when scanning for classes.

This implementation will return a new unmodifiable set containing the classloaders. Use the PackageScanClassResolver.addClassLoader(ClassLoader) method if you want to add new classloaders to the class loaders list.

Specified by:

getClassLoaders in interface PackageScanClassResolver

Returns:

the class loaders to use

addClassLoader

public void addClassLoader(ClassLoader classLoader)

Description copied from interface: PackageScanClassResolver

Adds the class loader to the existing loaders

Specified by:

addClassLoader in interface PackageScanClassResolver

Parameters:

classLoader - the loader to add

findAnnotated

public Set<Class<?>> findAnnotated(Class<? extends Annotation> annotation,
                                   String... packageNames)

Description copied from interface: PackageScanClassResolver

Attempts to discover classes that are annotated with to the annotation.

Specified by:

findAnnotated in interface PackageScanClassResolver

Parameters:

annotation - the annotation that should be present on matching classes

packageNames - one or more package names to scan (including subpackages) for classes

Returns:

the classes found, returns an empty set if none found

findAnnotated

public Set<Class<?>> findAnnotated(Set<Class<? extends Annotation>> annotations,
                                   String... packageNames)

Description copied from interface: PackageScanClassResolver

Attempts to discover classes that are annotated with to the annotation.

Specified by:

findAnnotated in interface PackageScanClassResolver

Parameters:

annotations - the annotations that should be present (any of them) on matching classes

packageNames - one or more package names to scan (including subpackages) for classes

Returns:

the classes found, returns an empty set if none found

findImplementations

public Set<Class<?>> findImplementations(Class<?> parent,
                                         String... packageNames)

Description copied from interface: PackageScanClassResolver

Attempts to discover classes that are assignable to the type provided. In the case that an interface is provided this method will collect implementations. In the case of a non-interface class, subclasses will be collected.

Specified by:

findImplementations in interface PackageScanClassResolver

Parameters:

parent - the class of interface to find subclasses or implementations of

packageNames - one or more package names to scan (including subpackages) for classes

Returns:

the classes found, returns an empty set if none found

findByFilter

public Set<Class<?>> findByFilter(PackageScanFilter filter,
                                  String... packageNames)

Description copied from interface: PackageScanClassResolver

Attempts to discover classes filter by the provided filter

Specified by:

findByFilter in interface PackageScanClassResolver

Parameters:

filter - filter to filter desired classes.

packageNames - one or more package names to scan (including subpackages) for classes

Returns:

the classes found, returns an empty set if none found

addFilter

public void addFilter(PackageScanFilter filter)

Description copied from interface: PackageScanClassResolver

Add a filter that will be applied to all scan operations

Specified by:

addFilter in interface PackageScanClassResolver

Parameters:

filter - filter to filter desired classes in all scan operations

removeFilter

public void removeFilter(PackageScanFilter filter)

Description copied from interface: PackageScanClassResolver

Removes the filter

Specified by:

removeFilter in interface PackageScanClassResolver

Parameters:

filter - filter to filter desired classes in all scan operations
