@Properties(inherit=javacpp.class) public class DoublePointer extends Pointer
double.
All operations take into account the position and limit, when appropriate.Pointer.CustomDeallocator, Pointer.Deallocator, Pointer.NativeDeallocator, Pointer.ReferenceCounter| Constructor and Description |
|---|
DoublePointer() |
DoublePointer(double... array)
Allocates enough memory for the array and copies it.
|
DoublePointer(java.nio.DoubleBuffer buffer)
For direct buffers, calls
Pointer.Pointer(Buffer), while for buffers
backed with an array, allocates enough memory for the array and copies it. |
DoublePointer(long size)
Allocates a native
double array of the given size. |
DoublePointer(Pointer p) |
| Modifier and Type | Method and Description |
|---|---|
java.nio.DoubleBuffer |
asBuffer()
Same as
Pointer.asByteBuffer(), but can be overridden to return subclasses of Buffer. |
DoublePointer |
capacity(long capacity)
Sets the capacity and returns this.
|
double |
get() |
DoublePointer |
get(double[] array) |
DoublePointer |
get(double[] array,
int offset,
int length)
Reads a portion of the native array into a Java array.
|
double |
get(long i) |
DoublePointer |
limit(long limit)
Sets the limit and returns this.
|
DoublePointer |
position(long position)
Sets the position and returns this.
|
DoublePointer |
put(double... array) |
DoublePointer |
put(double d) |
DoublePointer |
put(double[] array,
int offset,
int length)
Writes a portion of a Java array into the native array.
|
DoublePointer |
put(long i,
double d)
Copies the
double value to the i-th element of a native array. |
int |
sizeof()
Returns 1 for Pointer or BytePointer else
Loader.sizeof(getClass()) or -1 on error. |
