Constructor Detail

ConstructorInfo

protected ConstructorInfo(ClassInfo declaringClass,
                          Constructor<?> c,
                          Constructor<?> rc)

Constructor.

Parameters:

declaringClass - The class that declares this method.

c - The constructor being wrapped.

rc - The "real" constructor if the constructor above is defined against a CGLIB proxy.

Method Detail

of

public static ConstructorInfo of(ClassInfo declaringClass,
                                 Constructor<?> c,
                                 Constructor<?> rc)

Convenience method for instantiating a ConstructorInfo;

Parameters:

declaringClass - The class that declares this method.

c - The constructor being wrapped.

rc - The "real" constructor if the constructor above is defined against a CGLIB proxy.

Returns:

A new ConstructorInfo object, or null if the method was null;

of

public static ConstructorInfo of(Constructor<?> c)

Convenience method for instantiating a ConstructorInfo;

Parameters:

c - The constructor being wrapped.

Returns:

A new ConstructorInfo object, or null if the method was null;

inner

public <T> Constructor<T> inner()

Returns the wrapped method.

Returns:

The wrapped method.

invoke

public <T> T invoke(Object... args)
             throws ExecutableException

Shortcut for calling the new-instance method on the underlying constructor.

Parameters:

args - the arguments used for the method call

Returns:

The object returned from the constructor.

Throws:

ExecutableException - Exception occurred on invoked constructor/method/field.

makeAccessible

public ConstructorInfo makeAccessible(Visibility v)

Makes constructor accessible if it matches the visibility requirements, or returns null if it doesn't.

Security exceptions thrown on the call to AccessibleObject.setAccessible(boolean) are quietly ignored.

Parameters:

v - The minimum visibility.

Returns:

The same constructor if visibility requirements met, or null if visibility requirement not met or call to AccessibleObject.setAccessible(boolean) throws a security exception.

compareTo

public int compareTo(ConstructorInfo o)

Specified by:

compareTo in interface Comparable<ConstructorInfo>
