  ch.javasoft.lang.reflect.Array

public class Array
extends Object

The Array class contains static methods to instantiate arrays for generic types.

Method Summary

static <T> T[]	newInstance(Class<T> componentType, int length) Creates a new array of the given component type.
static <T> T[][]	newInstance(Class<T> componentType, int rows, int cols) Creates a new array of the given component type.
static <T> T[]	newInstanceInstantiate(Class<T> componentType, int length) Creates a new array of the given component type, and initializes the array with new instances by calling the default constructor of componentType
static <T> T[][]	newInstanceInstantiate(Class<T> componentType, int rows, int cols) Creates a new array of the given component type, and initializes the array with new instances by calling the default constructor of componentType

Method Detail

newInstance

public static final <T> T[] newInstance(Class<T> componentType,
                                        int length)

Creates a new array of the given component type. The new array contains null values

Type Parameters:

T - the component type generic parameter

Parameters:

componentType - the component type class

length - the length of the new array

Returns:

the array

newInstance

public static final <T> T[][] newInstance(Class<T> componentType,
                                          int rows,
                                          int cols)

Creates a new array of the given component type. The new array contains null values

Type Parameters:

T - the component type generic parameter

Parameters:

componentType - the component type class

rows - the length of the first dimension of the new array

cols - the length of the second dimension of the new array

Returns:

the array

newInstanceInstantiate

public static final <T> T[] newInstanceInstantiate(Class<T> componentType,
                                                   int length)
                                        throws InstantiationException,
                                               IllegalAccessException

Creates a new array of the given component type, and initializes the array with new instances by calling the default constructor of componentType

Type Parameters:

T - the component type generic parameter

Parameters:

componentType - the component type class

length - the length of the new array

Returns:

the array with new instances

Throws:

InstantiationException - if calling the default constructor fails

IllegalAccessException - if calling the default constructor fails

newInstanceInstantiate

public static final <T> T[][] newInstanceInstantiate(Class<T> componentType,
                                                     int rows,
                                                     int cols)
                                          throws InstantiationException,
                                                 IllegalAccessException

Creates a new array of the given component type, and initializes the array with new instances by calling the default constructor of componentType

Type Parameters:

T - the component type generic parameter

Parameters:

componentType - the component type class

rows - the length of the first dimension of the new array

cols - the length of the second dimension of the new array

Returns:

the array with new instances

Throws:

InstantiationException - if calling the default constructor fails

IllegalAccessException - if calling the default constructor fails
