getTypeParameters

public java.lang.reflect.TypeVariable[] getTypeParameters()

Returns an array of TypeVariable objects that represent the type variables declared by the generic declaration represented by this GenericDeclaration object, in declaration order. Returns an array of length 0 if the underlying generic declaration declares no type variables.

Returns:

an array of TypeVariable objects that represent the type variables declared by this generic declaration

Throws:

java.lang.reflect.GenericSignatureFormatError - if the generic signature of this generic declaration does not conform to the format specified in the Java Virtual Machine Specification, 3rd edition

getGenericParameterTypes

public java.lang.reflect.Type[] getGenericParameterTypes()

Returns an array of Type objects that represent the formal parameter types, in declaration order, of the method represented by this Constructor object. Returns an array of length 0 if the underlying method takes no parameters.

If a formal parameter type is a parameterized type, the Type object returned for it must accurately reflect the actual type parameters used in the source code.

If a formal parameter type is a type variable or a parameterized type, it is created. Otherwise, it is resolved.

Returns:

an array of Types that represent the formal parameter types of the underlying method, in declaration order

Throws:

java.lang.reflect.GenericSignatureFormatError - if the generic method signature does not conform to the format specified in the Java Virtual Machine Specification, 3rd edition

java.lang.TypeNotPresentException - if any of the parameter types of the underlying method refers to a non-existent type declaration

java.lang.reflect.MalformedParameterizedTypeException - if any of the underlying method's parameter types refer to a parameterized type that cannot be instantiated for any reason

getExceptionTypes

public ClassEx[] getExceptionTypes()

Returns an array of Class objects that represent the types of exceptions declared to be thrown by the underlying constructor represented by this Constructor object. Returns an array of length 0 if the constructor declares no exceptions in its throws clause.

Returns:

the exception types declared as being thrown by the constructor this object represents

getGenericExceptionTypes

public java.lang.reflect.Type[] getGenericExceptionTypes()

Returns an array of Type objects that represent the exceptions declared to be thrown by this Constructor object. Returns an array of length 0 if the underlying method declares no exceptions in its throws clause.

If an exception type is a parameterized type, the Type object returned for it must accurately reflect the actual type parameters used in the source code.

If an exception type is a type variable or a parameterized type, it is created. Otherwise, it is resolved.

Returns:

an array of Types that represent the exception types thrown by the underlying method

Throws:

java.lang.reflect.GenericSignatureFormatError - if the generic method signature does not conform to the format specified in the Java Virtual Machine Specification, 3rd edition

java.lang.TypeNotPresentException - if the underlying method's throws clause refers to a non-existent type declaration

java.lang.reflect.MalformedParameterizedTypeException - if the underlying method's throws clause refers to a parameterized type that cannot be instantiated for any reason

equals

public boolean equals(java.lang.Object obj)

Compares this Constructor against the specified object. Returns true if the objects are the same. Two Constructor objects are the same if they were declared by the same class and have the same formal parameter types.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Returns a hashcode for this Constructor. The hashcode is the same as the hashcode for the underlying constructor's declaring class name.

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Returns a string describing this Constructor. The string is formatted as the constructor access modifiers, if any, followed by the fully-qualified name of the declaring class, followed by a parenthesized, comma-separated list of the constructor's formal parameter types. For example:

    public java.util.Hashtable(int,float)
 

The only possible modifiers for constructors are the access modifiers public, protected or private. Only one of these may appear, or none if the constructor has default (package) access.

Overrides:

toString in class java.lang.Object

toGenericString

public java.lang.String toGenericString()

Returns a string describing this Constructor, including type parameters. The string is formatted as the constructor access modifiers, if any, followed by an angle-bracketed comma separated list of the constructor's type parameters, if any, followed by the fully-qualified name of the declaring class, followed by a parenthesized, comma-separated list of the constructor's generic formal parameter types. A space is used to separate access modifiers from one another and from the type parameters or return type. If there are no type parameters, the type parameter list is elided; if the type parameter list is present, a space separates the list from the class name. If the constructor is declared to throw exceptions, the parameter list is followed by a space, followed by the word "throws" followed by a comma-separated list of the thrown exception types.

The only possible modifiers for constructors are the access modifiers public, protected or private. Only one of these may appear, or none if the constructor has default (package) access.

Returns:

a string describing this Constructor, include type parameters

newInstance

public T newInstance(java.lang.Object[] initargs)
              throws java.lang.InstantiationException,
                     java.lang.IllegalAccessException,
                     java.lang.IllegalArgumentException,
                     java.lang.reflect.InvocationTargetException

Uses the constructor represented by this Constructor object to create and initialize a new instance of the constructor's declaring class, with the specified initialization parameters. Individual parameters are automatically unwrapped to match primitive formal parameters, and both primitive and reference parameters are subject to method invocation conversions as necessary.

If the number of formal parameters required by the underlying constructor is 0, the supplied initargs array may be of length 0 or null.

If the required access and argument checks succeed and the instantiation will proceed, the constructor's declaring class is initialized if it has not already been initialized.

If the constructor completes normally, returns the newly created and initialized instance.

Parameters:

initargs - array of objects to be passed as arguments to the constructor call; values of primitive types are wrapped in a wrapper object of the appropriate type (e.g. a float in a Float)

Returns:

a new object created by calling the constructor this object represents

Throws:

java.lang.IllegalAccessException - if this Constructor object enforces Java language access control and the underlying constructor is inaccessible.

java.lang.IllegalArgumentException - if the number of actual and formal parameters differ; if an unwrapping conversion for primitive arguments fails; or if, after possible unwrapping, a parameter value cannot be converted to the corresponding formal parameter type by a method invocation conversion; if this constructor pertains to an enum type.

java.lang.InstantiationException - if the class that declares the underlying constructor represents an abstract class.

java.lang.reflect.InvocationTargetException - if the underlying constructor throws an exception.

java.lang.ExceptionInInitializerError - if the initialization provoked by this method fails.

isVarArgs

public boolean isVarArgs()

Returns true if this constructor was declared to take a variable number of arguments; returns false otherwise.

Returns:

true if an only if this constructor was declared to take a variable number of arguments.

isSynthetic

public boolean isSynthetic()

Returns true if this constructor is a synthetic constructor; returns false otherwise.

Returns:

true if and only if this constructor is a synthetic constructor as defined by the Java Language Specification.

getParameterTypes

public ClassEx[] getParameterTypes()

Returns an array of Class objects that represent the formal parameter types, in declaration order, of the constructor represented by this Constructor object. Returns an array of length 0 if the underlying constructor takes no parameters.

Returns:

the parameter types for the constructor this object represents

getParameterAnnotations

public java.lang.annotation.Annotation[][] getParameterAnnotations()

Returns an array of arrays that represent the annotations on the formal parameters, in declaration order, of the method represented by this Method object. (Returns an array of length zero if the underlying method is parameterless. If the method has one or more parameters, a nested array of length zero is returned for each parameter with no annotations.) The annotation objects contained in the returned arrays are serializable. The caller of this method is free to modify the returned arrays; it will have no effect on the arrays returned to other callers.

Returns:

an array of arrays that represent the annotations on the formal parameters, in declaration order, of the method represented by this Method object

getLocalVariableAnnotations

public java.util.Map<java.lang.String,java.lang.annotation.Annotation[]> getLocalVariableAnnotations()

Returns a map from local variable names to arrays of annotations associated with them.

Returns:

map from local variable name to arrays of annotations
