GenericDeclaration

AI-generated Key Takeaways

• GenericDeclaration is an interface for entities that declare type variables.

• It provides a method, getTypeParameters(), to access declared type variables.

• getTypeParameters() returns an array of TypeVariable objects representing the declared type variables.

• If the declaration has no type variables, getTypeParameters() returns an empty array.

• A GenericSignatureFormatError is thrown if the signature is invalid.

public interface GenericDeclaration

Known Indirect Subclasses Class<T>, Constructor<T>, Executable, Method Class<T> Instances of the class Class represent classes and interfaces in a running Java application.  Constructor<T> Constructor provides information about, and access to, a single constructor for a class.  Executable A shared superclass for the common functionality of Method and Constructor.  Method A Method provides information about, and access to, a single method on a class or interface.

A common interface for all entities that declare type variables.
