Constructor and Description |
---|
FloatPointer() |
FloatPointer(float... array)
Allocates enough memory for the array and copies it.
|
FloatPointer(FloatBuffer buffer)
For direct buffers, calls
Pointer.Pointer(Buffer) , while for buffers
backed with an array, allocates enough memory for the array and copies it. |
FloatPointer(long size)
Allocates a native
float array of the given size. |
FloatPointer(Pointer p) |
Modifier and Type | Method and Description |
---|---|
private void |
allocateArray(long size) |
FloatBuffer |
asBuffer()
Same as
Pointer.asByteBuffer() , but can be overridden to return subclasses of Buffer. |
FloatPointer |
capacity(long capacity)
Sets the capacity and returns this.
|
float |
get() |
FloatPointer |
get(float[] array) |
FloatPointer |
get(float[] array,
int offset,
int length)
Reads a portion of the native array into a Java array.
|
float |
get(long i) |
FloatPointer |
limit(long limit)
Sets the limit and returns this.
|
FloatPointer |
position(long position)
Sets the position and returns this.
|
FloatPointer |
put(float... array) |
FloatPointer |
put(float f) |
FloatPointer |
put(float[] array,
int offset,
int length)
Writes a portion of a Java array into the native array.
|
FloatPointer |
put(long i,
float f)
Copies the
float 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. |
