Class CLongPointer

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.CLongPointer

public class CLongPointer
extends Pointer

The peer class to native pointers and arrays of long. All operations take into account the position and limit, when appropriate.

We need this class because platforms supported by Java do not all agree on the size of the native C++ long type, unlike int and short.

Constructor Detail

CLongPointer

public CLongPointer(int size)

Allocates a native long array of the given size.

Parameters:

size - the number of long elements to allocate

CLongPointer

public CLongPointer()

See Also:

Pointer.Pointer()

CLongPointer

public CLongPointer(Pointer p)

See Also:

Pointer.Pointer(Pointer)

Method Detail

allocateArray

private void allocateArray(int size)

position

public CLongPointer position(int position)

Description copied from class: Pointer

Sets the position and returns this. That makes the array.position(i) statement sort of equivalent to the array[i] statement in C++.

Overrides:

position in class Pointer

Parameters:

position - the new position

Returns:

this

See Also:

Pointer.position(int)

limit

public CLongPointer limit(int limit)

Description copied from class: Pointer

Sets the limit and returns this. Used to limit the size of an operation on this object.

Overrides:

limit in class Pointer

Parameters:

limit - the new limit

Returns:

this

See Also:

Pointer.limit(int)

capacity

public CLongPointer capacity(int capacity)

Description copied from class: Pointer

Sets the capacity and returns this. Should not be called more than once after allocation.

Overrides:

capacity in class Pointer

Parameters:

capacity - the new capacity

Returns:

this

See Also:

Pointer.capacity(int)

get

public long get()

Returns:

get(0)

get

public long get(int i)

Returns:

the i-th long value of a native array

put

public CLongPointer put(long l)

Returns:

put(0, l)

put

public CLongPointer put(int i,
               long l)

Copies the long value to the i-th element of a native array.

Parameters:

i - the index into the array

l - the long value to copy

Returns:

this
