方法详细资料

invoke

public Object invoke(Object proxy,
 Method method,
 Object[] args)

指定者:

invoke 在接口中 InvocationHandler

annotationEquals

private boolean annotationEquals(Object proxy,
 Object other)

See Annotation.equals(Object) for a definition of the required algorithm.

参数:

other - the other object to compare against

annotationHashCode

private int annotationHashCode()

See Annotation.hashCode() for a definition of the required algorithm.

computeHashCode

private Integer computeHashCode()

annotationToString

private String annotationToString()

toString

private String toString(Object value)

This method currently does not address the following issues which we may choose to address at a later point in time.

• non-ASCII, non-visible, and non-printable characters within a character or String literal are not escaped.
• formatting for float and double values does not take into account whether a value is not a number (NaN) or infinite.

参数:

value - the attribute value to format

返回:

the formatted string representation

getAttributeValue

private Object getAttributeValue(Method method,
 boolean cloneArray)

cloneArray

private static Object cloneArray(Object array)

Clone the provided array, ensuring that the original component type is retained.

参数:

array - the array to clone

createProxy

static <A extends Annotation> A createProxy(AbstractMergedAnnotation<A> annotation,
 Class<A> type)
