Method Detail

wrap

public static ArraySubVector wrap(double[] data,
                  int offset,
                  int length)

length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector

get

public double get(int i)

Specified by:

get in interface IVector

Specified by:

get in class AVector

set

public void set(int i,
       double value)

Specified by:

set in interface IVector

Specified by:

set in class AVector

add

public void add(ArrayVector v)

Overrides:

add in class ArrayVector

addMultiple

public void addMultiple(ArrayVector v,
               double factor)

Overrides:

addMultiple in class ArrayVector

fill

public void fill(double value)

Description copied from class: AVector

Fills a vector with a given value

Overrides:

fill in class AVector

multiply

public void multiply(double factor)

Description copied from class: AVector

Multiplies the vector by a constant factor

Overrides:

multiply in class AVector

Parameters:

factor - Factor by which to multiply each component of the vector

hashCode

public int hashCode()

Vector hashcode, designed to match hashcode of Java double array

Overrides:

hashCode in class AVector

getArray

public double[] getArray()

Specified by:

getArray in class ArrayVector

getArrayOffset

public int getArrayOffset()

Specified by:

getArrayOffset in class ArrayVector

isReference

public boolean isReference()

Description copied from class: AVector

Returns true if this vector is of a type that references other vectors / data.

Overrides:

isReference in class AVector

Returns:

clone

public AVector clone()

Description copied from class: AVector

Clones the vector, creating a new copy of all data. The clone is: - not guaranteed to be of the same type. - guaranteed to be fully mutable - guaranteed not to contain a reference (i.e. is a full deep copy)

Overrides:

clone in class AVector
