Detailed Description

Constructor provides information about, and access to, a single constructor for a class.

Constructor permits widening conversions to occur when matching the actual parameters to newInstance() with the underlying constructor's formal parameters, but throws an IllegalArgumentException if a narrowing conversion would occur.

Constructor & Destructor Documentation

java::lang::reflect::Constructor::Constructor (  const ::java::lang::Class &  declaringClass, const ::xmog_java_array_template< ::java::lang::Class > &  parameterTypes, const ::xmog_java_array_template< ::java::lang::Class > &  checkedExceptions, jint  modifiers, jint  slot, ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

Package-private constructor used by ReflectAccess to enable instantiation of these objects in Java code from the java.lang package via sun.reflect.LangReflectAccess. Parameters: declaringClass  a reference to an outer class instance. parameterTypes  a reference to an outer class instance. checkedExceptions  a reference to an outer class instance. modifiers  a reference to an outer class instance. slot  a reference to an outer class instance. p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL.

Member Function Documentation

bool java::lang::reflect::Constructor::equals (  const ::java::lang::Object &  obj, ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )  [virtual]

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. Parameters: obj  a reference to an outer class instance. p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::Object.

::java::lang::Class java::lang::reflect::Constructor::getDeclaringClass (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

Returns the Class object representing the class that declares the constructor represented by this Constructor object. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::reflect::Member.

::xmog_java_array_template< ::java::lang::Class > java::lang::reflect::Constructor::getExceptionTypes (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

Returns an array of Class objects that represent the types of 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. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: the exception types declared as being thrown by the constructor this object represents

jint java::lang::reflect::Constructor::getModifiers (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )  [virtual]

Returns the Java language modifiers for the constructor represented by this Constructor object, as an integer. The Modifier class should be used to decode the modifiers. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::reflect::Member.

::java::lang::String java::lang::reflect::Constructor::getName (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

Returns the name of this constructor, as a string. This is always the same as the simple name of the constructor's declaring class. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::reflect::Member.

::xmog_java_array_template< ::java::lang::Class > java::lang::reflect::Constructor::getParameterTypes (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

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. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: the parameter types for the constructor this object represents

jint java::lang::reflect::Constructor::hashCode (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )  [virtual]

Returns a hashcode for this Constructor. The hashcode is the same as the hashcode for the underlying constructor's declaring class name. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::Object.

::java::lang::Object java::lang::reflect::Constructor::newInstance (  const ::xmog_java_array_template< ::java::lang::Object > &  initargs, ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

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) p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: a new object created by calling the constructor this object represents

::java::lang::String java::lang::reflect::Constructor::toString (  ::xmog_localenv *  p_xenv = NULL, xmog_flags  f_xflags = xmogDefaultFlags )

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. Parameters: p_xenv  the local call environment. The default value is NULL. f_xflags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: Reimplemented from java::lang::Object.
