Class BoolPointer

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.javacpp.BoolPointer

public class BoolPointer
extends Pointer

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

We need this class because C++ does not define the size of the bool type.

Constructor Detail

BoolPointer

public BoolPointer(int size)

Allocates a native bool array of the given size.

Parameters:

size - the number of bool elements to allocate

BoolPointer

public BoolPointer()

See Also:

Pointer.Pointer()

BoolPointer

public BoolPointer(Pointer p)

See Also:

Pointer.Pointer(Pointer)

Method Detail

allocateArray

private void allocateArray(int size)

position

public BoolPointer 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 BoolPointer 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 BoolPointer 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 boolean get()

Returns:

get(0)

get

public boolean get(int i)

Returns:

the i-th bool value of a native array

put

public BoolPointer put(boolean b)

Returns:

put(0, b)

put

public BoolPointer put(int i,
              boolean b)

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

Parameters:

i - the index into the array

b - the bool value to copy

Returns:

this
