Interface EnclosingMethodAttribute
- All Superinterfaces:
- Attribute<EnclosingMethodAttribute>,- ClassElement,- ClassFileElement
public sealed interface EnclosingMethodAttribute
extends Attribute<EnclosingMethodAttribute>, ClassElement
Models the 
EnclosingMethod attribute
 (JVMS 4.7.7), which indicates that this class is a local or
 anonymous class, and indicates the enclosing method or constructor of this
 class if this class is enclosed in exactly one method or constructor.
 This attribute only appears on classes, and does not permit multiple instances in a class. It has a data dependency on the constant pool.
The attribute was introduced in the Java SE Platform version 5.0, major version 49.

Method Details- 
enclosingClassClassEntry enclosingClass()Returns the class that encloses the declaration of the current class. If theenclosingMethod()is present, this is the declaring class of that enclosing method or constructor.- Returns:
- the class that encloses the declaration of the current class
- See Also:
 
- 
enclosingMethodOptional<NameAndTypeEntry> enclosingMethod()Returns the name and type of the enclosing method, if the class is immediately enclosed by exactly one method or constructor. This may be empty if the anonymous or local class appears in a field initializer (JLS 8.3.2), an instance initializer (JLS 8.6), or a static initializer (JLS 8.7). As a result, this never describes a class initialization method "<clinit>".- Returns:
- the name and type of the enclosing method, if the class is immediately enclosed by exactly one method or constructor
