Class ClassTypeCallback<R>

java.lang.Object

ch.jalu.typeresolver.classutil.ClassTypeCallback<R>

Type Parameters:

R - the result type of the callback

public abstract class ClassTypeCallback<R>
extends Object

Extendable class with a method dedicated for each ClassType, with appropriately cast method parameters. This class's methods are meant to be overridden. The methods can be overridden partially if only certain class types are of interest.

Modifier and Type	Method and Description
R	forAnnotation(Class<? extends Annotation> annotationClass) Called when the class to process represents an annotation, such as Override.
R	forArrayType(Class<?> arrayClass) Called when the class to process is an array class, such as int[].class or String[][].class.
R	forEnum(Class<? extends Enum<?>> enumClass) Called when the class to process represents an enum, such as TimeUnit.
R	forEnumEntry(Class<? extends Enum<?>> enumClass, Class<? extends Enum<?>> enumEntryClass) Called when the class to process is a synthetic class of an enum entry, which is created when an enum extends the enum class anonymously (see ClassType.ENUM_ENTRY).
R	forInterface(Class<?> interfaceType) Called when the class to process is an interface, such as Map.
R	forPrimitiveType(Class<?> primitiveClass) Called when the class to process represents a primitive type, such as int.class, or void.class.
R	forProxyClass(Class<?> proxyClass) Called when the class to process is a dynamic proxy, cf.
R	forRegularClass(Class<?> regularClass) Called when the class to process is a "regular class", as explained in ClassUtils.isRegularJavaClass(java.lang.Class<?>).

Method Detail

forEnum

@Nullable
public R forEnum(Class<? extends Enum<?>> enumClass)

Called when the class to process represents an enum, such as TimeUnit.

Parameters:

enumClass - the enum class

Returns:

result or null

forEnumEntry

@Nullable
public R forEnumEntry(Class<? extends Enum<?>> enumClass,
                                Class<? extends Enum<?>> enumEntryClass)

Called when the class to process is a synthetic class of an enum entry, which is created when an enum extends the enum class anonymously (see ClassType.ENUM_ENTRY). This method is called with the enum class (e.g. Range) and the concrete enum entry class that was given to process.

Parameters:

enumClass - the enum class

enumEntryClass - the synthetic class of the enum entry

Returns:

result or null

forAnnotation

@Nullable
public R forAnnotation(Class<? extends Annotation> annotationClass)

Called when the class to process represents an annotation, such as Override.

Parameters:

annotationClass - the annotation class

Returns:

result or null

forPrimitiveType

@Nullable
public R forPrimitiveType(Class<?> primitiveClass)

Called when the class to process represents a primitive type, such as int.class, or void.class.

Parameters:

primitiveClass - the primitive class (or void)

Returns:

result or null

forArrayType

@Nullable
public R forArrayType(Class<?> arrayClass)

Called when the class to process is an array class, such as int[].class or String[][].class.

Note that the class cannot be cast to Class<? extends Object[]> without checking beforehand, due to arrays of primitive types such as int[].class.

Parameters:

arrayClass - the array class

Returns:

result or null

forInterface

@Nullable
public R forInterface(Class<?> interfaceType)

Called when the class to process is an interface, such as Map.

Parameters:

interfaceType - the interface

Returns:

result or null

forProxyClass

@Nullable
public R forProxyClass(Class<?> proxyClass)

Called when the class to process is a dynamic proxy, cf. Proxy.

Parameters:

proxyClass - the proxy class

Returns:

result or null

forRegularClass

@Nullable
public R forRegularClass(Class<?> regularClass)

Called when the class to process is a "regular class", as explained in ClassUtils.isRegularJavaClass(java.lang.Class<?>).

Parameters:

regularClass - the Java class

Returns:

result or null
