Class Constructor<T>

public boolean equals(Object obj)

Compare two objects to see if they are semantically equivalent. Two Constructors are semantically equivalent if they have the same declaring class and the same parameter list.

Overrides:

equals in interface Object

Parameters:

Returns:

true if they are equal; false if not.

public extends Annotation> T getAnnotation(Class annoClass)

Returns the element's annotation for the specified annotation type, or null if no such annotation exists.

This method must be overridden by subclasses to provide appropriate behaviour.

Specified by:

extends Annotation> T getAnnotation in interface AnnotatedElement

Overrides:

extends Annotation> T getAnnotation in interface AccessibleObject

Parameters:

Returns:

this element's annotation for the specified type, or null if no such annotation exists.

Throws:

NullPointerException - if the annotation class is null.

public Annotation[] getDeclaredAnnotations()

Returns all annotations directly defined by the element. If there are no annotations directly associated with the element, then a zero-length array will be returned. The returned array may be modified by the client code, but this will have no effect on the annotation content of this class, and hence no effect on the return value of this method for future callers.

This method must be overridden by subclasses to provide appropriate behaviour.

Specified by:

getDeclaredAnnotations in interface AnnotatedElement

Overrides:

getDeclaredAnnotations in interface AccessibleObject

Returns:

the annotations directly defined by the element.

Since:

1.5

public Class getDeclaringClass()

Gets the class that declared this constructor.

Specified by:

getDeclaringClass in interface Member

Returns:

the class that declared this member

public Class[] getExceptionTypes()

Get the exception types this constructor says it throws, in no particular order. If the constructor has no throws clause, returns a 0-length array (not null).

Returns:

a list of the types in the constructor's throws clause

public Type[] getGenericExceptionTypes()

Returns an array of Type objects that represents the exception types declared by this constructor, in declaration order. An array of size zero is returned if this constructor declares no exceptions.

Returns:

the exception types declared by this constructor.

Since:

1.5

public Type[] getGenericParameterTypes()

Returns an array of Type objects that represents the parameter list for this constructor, in declaration order. An array of size zero is returned if this constructor takes no parameters.

Returns:

a list of the types of the constructor's parameters

Since:

1.5

public int getModifiers()

Gets the modifiers this constructor uses. Use the Modifier class to interpret the values. A constructor can only have a subset of the following modifiers: public, private, protected.

Specified by:

getModifiers in interface Member

Returns:

an integer representing the modifiers to this Member

See Also:

Modifier

public String getName()

Gets the name of this constructor (the non-qualified name of the class it was declared in).

Specified by:

getName in interface Member

Returns:

the name of this constructor

public Annotation[][] getParameterAnnotations()

public Class[] getParameterTypes()

Get the parameter list for this constructor, in declaration order. If the constructor takes no parameters, returns a 0-length array (not null).

Returns:

a list of the types of the constructor's parameters

public TypeVariable>[] getTypeParameters()

Returns an array of TypeVariable objects that represents the type variables declared by this constructor, in declaration order. An array of size zero is returned if this constructor has no type variables.

Specified by:

getTypeParameters in interface GenericDeclaration

Returns:

the type variables associated with this constructor.

Since:

1.5

public int hashCode()

Get the hash code for the Constructor. The Constructor hash code is the hash code of the declaring class's name.

Overrides:

hashCode in interface Object

Returns:

the hash code for the object

public boolean isSynthetic()

Return true if this constructor is synthetic, false otherwise. A synthetic member is one which is created by the compiler, and which does not appear in the user's source code.

Specified by:

isSynthetic in interface Member

Since:

1.5

public boolean isVarArgs()

Return true if this is a varargs constructor, that is if the constructor takes a variable number of arguments.

Since:

1.5

public T newInstance(java.lang.Object... args)
            throws InstantiationException,
                   IllegalAccessException,
                   IllegalArgumentException,
                   InvocationTargetException

Create a new instance by invoking the constructor. Arguments are automatically unwrapped and widened, if needed.

If this class is abstract, you will get an InstantiationException. If the constructor takes 0 arguments, you may use null or a 0-length array for args.

If this Constructor enforces access control, your runtime context is evaluated, and you may have an IllegalAccessException if you could not create this object in similar compiled code. If the class is uninitialized, you trigger class initialization, which may end in a ExceptionInInitializerError.

Then, the constructor is invoked. If it completes normally, the return value will be the new object. If it completes abruptly, the exception is wrapped in an InvocationTargetException.

Parameters:

args - the arguments to the constructor

Returns:

the newly created object

Throws:

IllegalAccessException - if the constructor could not normally be called by the Java code (i.e. it is not public)

IllegalArgumentException - if the number of arguments is incorrect; or if the arguments types are wrong even with a widening conversion

InstantiationException - if the class is abstract

InvocationTargetException - if the constructor throws an exception

public String toGenericString()

public String toString()

Get a String representation of the Constructor. A Constructor's String representation is "<modifier> <classname>(<paramtypes>) throws <exceptions>", where everything after ')' is omitted if there are no exceptions.
Example: public java.io.FileInputStream(java.lang.Runnable) throws java.io.FileNotFoundException

Overrides:

toString in interface Object

Returns:

the String representation of the Constructor
