saker.build.runtime.classpath.ClassPathServiceEnumerator<T>

java.io.Externalizable

java.io.Serializable

ClassPathServiceEnumerator implementation for locating a service for a class name and expected type.

The implementation will throw a ClassPathEnumerationError if the retrieved class is not an instance of the expected type.

TThe type of the requested service.

Constructors

public	NamedCheckingClassPathServiceEnumerator() For Externalizable.
public	NamedCheckingClassPathServiceEnumerator(String className, Class<?> expectedInstanceOf) Creates a new enumerator for the given class name and expected type.

Methods

protected Iterable<? extends T>	createIterable(Class<?> found) Creates a lazily instantiating Iterable for the found class.
public Class<?>	getExpectedInstanceOfClass() Gets the class that the service is expected to be an instance of.
public void	readExternal(ObjectInput in) The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays.
public void	writeExternal(ObjectOutput out) The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.

public NamedCheckingClassPathServiceEnumerator()

For Externalizable.

public NamedCheckingClassPathServiceEnumerator(String className, Class<?> expectedInstanceOf) throws NullPointerException

Creates a new enumerator for the given class name and expected type.

classNameThe class name of the service to look up.

expectedInstanceOfThe expected type to check the service for.

NullPointerExceptionIf any of the arguments are null.

protected Iterable<? extends T> createIterable(Class<?> found)

Overridden from: NamedClassPathServiceEnumerator

Creates a lazily instantiating Iterable for the found class.

foundThe found class.

The created iterable.

public Class<?> getExpectedInstanceOfClass()

Gets the class that the service is expected to be an instance of.

The class.

public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException

Overridden from: Externalizable

The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

IOExceptionif I/O errors occur

ClassNotFoundExceptionIf the class for an object being restored cannot be found.

public void writeExternal(ObjectOutput out) throws IOException

Overridden from: Externalizable

The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays.
