构造器详细资料

SynthesizingMethodParameter

public SynthesizingMethodParameter(Method method,
 int parameterIndex)

Create a new SynthesizingMethodParameter for the given method, with nesting level 1.

参数:

method - the Method to specify a parameter for

parameterIndex - the index of the parameter: -1 for the method return type; 0 for the first method parameter; 1 for the second method parameter, etc.

SynthesizingMethodParameter

public SynthesizingMethodParameter(Method method,
 int parameterIndex,
 int nestingLevel)

Create a new SynthesizingMethodParameter for the given method.

参数:

method - the Method to specify a parameter for

parameterIndex - the index of the parameter: -1 for the method return type; 0 for the first method parameter; 1 for the second method parameter, etc.

nestingLevel - the nesting level of the target type (typically 1; e.g. in case of a List of Lists, 1 would indicate the nested List, whereas 2 would indicate the element of the nested List)

SynthesizingMethodParameter

public SynthesizingMethodParameter(Constructor<?> constructor,
 int parameterIndex)

Create a new SynthesizingMethodParameter for the given constructor, with nesting level 1.

参数:

constructor - the Constructor to specify a parameter for

parameterIndex - the index of the parameter

SynthesizingMethodParameter

public SynthesizingMethodParameter(Constructor<?> constructor,
 int parameterIndex,
 int nestingLevel)

Create a new SynthesizingMethodParameter for the given constructor.

参数:

constructor - the Constructor to specify a parameter for

parameterIndex - the index of the parameter

nestingLevel - the nesting level of the target type (typically 1; e.g. in case of a List of Lists, 1 would indicate the nested List, whereas 2 would indicate the element of the nested List)

SynthesizingMethodParameter

protected SynthesizingMethodParameter(SynthesizingMethodParameter original)

Copy constructor, resulting in an independent SynthesizingMethodParameter based on the same metadata and cache state that the original object was in.

参数:

original - the original SynthesizingMethodParameter object to copy from

方法详细资料

adaptAnnotation

protected <A extends Annotation> A adaptAnnotation(A annotation)

从类复制的说明: MethodParameter

A template method to post-process a given annotation instance before returning it to the caller.

The default implementation simply returns the given annotation as-is.

覆盖:

adaptAnnotation 在类中 MethodParameter

参数:

annotation - the annotation about to be returned

返回:

the post-processed annotation (or simply the original one)

adaptAnnotationArray

protected Annotation[] adaptAnnotationArray(Annotation[] annotations)

从类复制的说明: MethodParameter

A template method to post-process a given annotation array before returning it to the caller.

The default implementation simply returns the given annotation array as-is.

覆盖:

adaptAnnotationArray 在类中 MethodParameter

参数:

annotations - the annotation array about to be returned

返回:

the post-processed annotation array (or simply the original one)

clone

public SynthesizingMethodParameter clone()

覆盖:

clone 在类中 MethodParameter

forExecutable

public static SynthesizingMethodParameter forExecutable(Executable executable,
 int parameterIndex)

Create a new SynthesizingMethodParameter for the given method or constructor.

This is a convenience factory method for scenarios where a Method or Constructor reference is treated in a generic fashion.

参数:

executable - the Method or Constructor to specify a parameter for

parameterIndex - the index of the parameter

返回:

the corresponding SynthesizingMethodParameter instance

forParameter

public static SynthesizingMethodParameter forParameter(Parameter parameter)

Create a new SynthesizingMethodParameter for the given parameter descriptor.

This is a convenience factory method for scenarios where a Java 8 Parameter descriptor is already available.

参数:

parameter - the parameter descriptor

返回:

the corresponding SynthesizingMethodParameter instance
