Method Details

getArrayType

Class<T> getArrayType()

isAssignableFrom

default boolean isAssignableFrom(Class<?> clazz)

isAssignableFromObject

default boolean isAssignableFromObject(Object o)

getLength

int getLength(T array)

A strongly-typed equivalent to Array.getLength(Object).

Parameters:

array - the array

Returns:

the length of the array

newInstance

T newInstance(int len)

A strongly-typed equivalent to Array.newInstance(Class, int).

Parameters:

len - the length of the new array

Returns:

the new array

arrayCopy

void arrayCopy(T src,
 int srcPos,
 T dest,
 int destPos,
 int length)

A strongly-typed equivalent to System.arraycopy(Object, int, Object, int, int).

Parameters:

src - the source array.

srcPos - starting position in the source array.

dest - the destination array.

destPos - starting position in the destination data.

length - the number of array elements to be copied.

copyOfRange

default T copyOfRange(T src,
 int from,
 int to)

A strongly-typed equivalent to Arrays.copyOfRange(Object[], int, int).

Parameters:

src - the array from which a range is to be copied

from - the initial index of the range to be copied, inclusive

to - the final index of the range to be copied, exclusive

Returns:

a new array containing the specified range from the original array
