Constructor Details

DoublePtr

public DoublePtr()

Creates a new DoublePtr with a value of 0.0.

DoublePtr

public DoublePtr(double value)

Creates a new DoublePtr and initializes it with the specified value.

Parameters:

value - the value.

Method Details

get

public double get()

Returns the current value.

Returns:

the value.

set

public void set(double value)

Sets the value.

Parameters:

value - the new value.

asDoubleBuffer

public DoubleBuffer asDoubleBuffer(int n)

Returns a DoubleBuffer which reads and writes to the same memory location pointed to by this DoublePtr.

Parameters:

n - the maximum number of doubles the DoubleBuffer can read/write. This will be the DoubleBuffer's capacity.

Returns:

the DoubleBuffer.

toDoubleArray

public double[] toDoubleArray(int n)

Copies n doubles from the memory pointed to by this DoublePtr to a new double[] instance.

Parameters:

n - the number of doubles to copy.

Returns:

the double[].

get

public void get(double[] dst)

Copies dst.length doubles from the memory pointed to by this DoublePtr to dst.

Parameters:

dst - the destination.

get

public void get(double[] dst,
int offset,
int count)

Copies count doubles from the memory pointed to by this DoublePtr to dst starting at offset offset.

Parameters:

dst - the destination.

offset - the offset within the destination array to start copying to.

count - the number of elements to copy.

set

public void set(double[] src)

Copies src.length doubles from src to the memory pointed to by this DoublePtr.

Parameters:

src - the source.

set

public void set(double[] src,
int offset,
int count)

Copies count doubles from src starting at offset offset to the memory pointed to by this DoublePtr.

Parameters:

src - the source.

offset - the offset within the source array to start copying from.

count - the number of elements to copy.
