Package org.bytedeco.javacpp
Class BooleanPointer
java.lang.Object
org.bytedeco.javacpp.Pointer
org.bytedeco.javacpp.BooleanPointer
- All Implemented Interfaces:
AutoCloseable
The peer class to native pointers and arrays of
jboolean
.
All operations take into account the position and limit, when appropriate.
Assumes sizeof(jboolean)
is always 1 byte with false == 0
and true == 1
.

array
- the array to copy- See Also:

BooleanPointer
For direct buffers, callsPointer(Buffer)
, while for buffers backed with an array, allocates enough memory for the array and copies it.- Parameters:
buffer
- the Buffer to reference or copy- See Also:
-

allocateArray
private void allocateArray(long size) -
position
Description copied from class:Pointer
Sets the position and returns this. That makes thearray.position(i)
statement sort of equivalent to thearray[i]
statement in C++. -
limit
Description copied from class:Pointer
Sets the limit and returns this. Used to limit the size of an operation on this object. -
capacity
Description copied from class:Pointer
Sets the capacity and returns this. Should not be called more than once after allocation. -
sizeof
public int sizeof()Description copied from class:Pointer
Returns 1 for Pointer or BytePointer elseLoader.sizeof(getClass())
or -1 on error. -
getPointer
Description copied from class:Pointer
ReturnsgetPointer(getClass(), i)
.- Overrides:
getPointer

-
get
public boolean get()- Returns:
get(0)
-
get
public boolean get(long i) - Returns:
- the i-th
boolean
value of a native array
-
put
- Returns:
put(0, b)
-
put
Copies theboolean
value to the i-th element of a native array.- Parameters:
i
- the index into the arrayb
- theboolean
value to copy- Returns:
- this
-
get
- Returns:
get(array, 0, array.length)
-
put
- Returns:
put(array, 0, array.length)
-
get
Reads a portion of the native array into a Java array.- Parameters:
array
- the array to write tooffset
- the offset into the array where to start writinglength
- the length of data to read and write- Returns:
- this
-
put
Writes a portion of a Java array into the native array.- Parameters:
array
- the array to read fromoffset
- the offset into the array where to start readinglength
- the length of data to read and write- Returns:
