Method Detail

dispatch

public final R dispatch(Type type,
                        C context)
                 throws E extends Throwable

Dispatches the suitable visit* method. This can dispatch the following methods:

• Class - visitClass(type, context)
• GenericArrayType - visitGenericArrayType(type, context)
• ParameterizedType - visitParameterizedType(type, context)
• TypeVariable - visitTypeVariable(type, context)
• WildcardType - visitWildcardType(type, context)

Parameters:

type - the type to be dispatched

context - the current context (nullable)

Returns:

the processing result in visit*

Throws:

E - if error was occurred while processing the target element visit*

IllegalArgumentException - if the type is neither Class, GenericArrayType, ParameterizedType, TypeVariable, nor WildcardType

E extends Throwable

visitClass

protected R visitClass(Class<?> type,
                       C context)
                throws E extends Throwable

Processes Class using this visitor.

Parameters:

type - the processing target

context - the current context (nullable)

Returns:

the processing result

Throws:

E - if error was occurred while processing the target type

E extends Throwable

                           throws E extends Throwable

Processes GenericArrayType using this visitor.

Parameters:

type - the processing target

context - the current context (nullable)

Returns:

the processing result

Throws:

E - if error was occurred while processing the target type

Processes ParameterizedType using this visitor.

Parameters:

type - the processing target

context - the current context (nullable)

Returns:

the processing result
