方法详细资料

visit

public void visit(String name,
 Object value)

从类复制的说明: AnnotationVisitor

Visits a primitive value of the annotation.

覆盖:

visit 在类中 AnnotationVisitor

参数:

name - the value name.

value - the actual value, whose type must be Byte, Boolean, Character, Short, Integer , Long, Float, Double, String or Type of Type.OBJECT or Type.ARRAY sort. This value can also be an array of byte, boolean, short, char, int, long, float or double values (this is equivalent to using AnnotationVisitor.visitArray(java.lang.String) and visiting each array element in turn, but is more convenient).

visitEnum

public void visitEnum(String name,
 String descriptor,
 String value)

从类复制的说明: AnnotationVisitor

Visits an enumeration value of the annotation.

覆盖:

visitEnum 在类中 AnnotationVisitor

参数:

name - the value name.

descriptor - the class descriptor of the enumeration class.

value - the actual enumeration value.

visitAnnotation

@Nullable
public AnnotationVisitor visitAnnotation(String name,
 String descriptor)

从类复制的说明: AnnotationVisitor

Visits a nested annotation value of the annotation.

覆盖:

visitAnnotation 在类中 AnnotationVisitor

参数:

name - the value name.

descriptor - the class descriptor of the nested annotation class.

返回:

a visitor to visit the actual nested annotation value, or null if this visitor is not interested in visiting this nested annotation. The nested annotation value must be fully visited before calling other methods on this annotation visitor.

visitArray

public AnnotationVisitor visitArray(String name)

从类复制的说明: AnnotationVisitor

Visits an array value of the annotation. Note that arrays of primitive values (such as byte, boolean, short, char, int, long, float or double) can be passed as value to visit. This is what ClassReader does for non empty arrays of primitive values.

覆盖:

visitArray 在类中 AnnotationVisitor

参数:

name - the value name.

返回:

a visitor to visit the actual array value elements, or null if this visitor is not interested in visiting these values. The 'name' parameters passed to the methods of this visitor are ignored. All the array values must be visited before calling other methods on this annotation visitor.

visitEnd

public void visitEnd()

从类复制的说明: AnnotationVisitor

Visits the end of the annotation.

覆盖:

visitEnd 在类中 AnnotationVisitor

visitEnum

public <E extends Enum<E>> void visitEnum(String descriptor,
 String value,
 Consumer<E> consumer)

visitAnnotation

@Nullable
private <T extends Annotation> AnnotationVisitor visitAnnotation(String descriptor,
 Consumer<MergedAnnotation<T>> consumer)
