Examples of java.lang.reflect.Method

java.lang.reflect.Method
A Method provides information about, and access to, a single method on a class or interface. The reflected method may be a class method or an instance method (including an abstract method).
A Method permits widening conversions to occur when matching the actual parameters to invoke with the underlying method's formal parameters, but it throws an IllegalArgumentException if a narrowing conversion would occur. @see Member @see java.lang.Class @see java.lang.Class#getMethods() @see java.lang.Class#getMethod(String,Class[]) @see java.lang.Class#getDeclaredMethods() @see java.lang.Class#getDeclaredMethod(String,Class[]) @author Kenneth Russell @author Nakul Saraiya
