Class GrowableVector

java.lang.Object

mikera.arrayz.impl.AbstractArray<Double>

mikera.vectorz.AVector

mikera.vectorz.impl.AStridedVector

mikera.vectorz.impl.AArrayVector

mikera.vectorz.GrowableVector

All Implemented Interfaces:

Serializable, Cloneable, Comparable<AVector>, Iterable<Double>, IStridedArray, INDArray, IVector

public final class GrowableVector
extends AArrayVector

Implements a growable vector, intended for incrementally building vectors Note that getting the underlying array or a subVector is unsafe, since the underlying array may be discarded as the vector is grown.

Constructor Detail

GrowableVector

public GrowableVector(AVector v)

GrowableVector

public GrowableVector()

Method Detail

ofInitialCapacity

public static GrowableVector ofInitialCapacity(int capacity)

Returns a new, empty GrowableVector with the specified initial capacity

getArray

public double[] getArray()

Gets the current underlying array of the GrowableVector. Since this array may be discarded by the GrowableVector, it is not safe to assume that it will continue to be a valid reference if the GrowableVector is changed.

Specified by:

getArray in interface IStridedArray

Specified by:

getArray in class AStridedVector

getArrayOffset

public int getArrayOffset()

Specified by:

getArrayOffset in interface IStridedArray

Specified by:

getArrayOffset in class AStridedVector

length

public int length()

Specified by:

length in interface IVector

Specified by:

length in class AVector

currentCapacity

public int currentCapacity()

ensureCapacity

public void ensureCapacity(int capacity)

get

public double get(int i)

Description copied from interface: INDArray

Returns the double value at the specified position in a 1D vector

Specified by:

get in interface INDArray

Specified by:

get in interface IVector

Specified by:

get in class AArrayVector

Returns:

set

public void set(int i,
       double value)

Specified by:

set in interface INDArray

Specified by:

set in interface IVector

Specified by:

set in class AArrayVector

unsafeGet

public double unsafeGet(int i)

Specified by:

unsafeGet in class AArrayVector

unsafeSet

public void unsafeSet(int i,
             double value)

Specified by:

unsafeSet in class AArrayVector

isView

public boolean isView()

Description copied from class: AVector

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

Specified by:

isView in interface INDArray

Overrides:

isView in class AArrayVector

Returns:

append

public void append(double v)

append

public void append(AVector v)

build

public AVector build()

Function to build a fixed-size vector containing a copy of data once the GrowableVector is constructed

Returns:

clone

public GrowableVector 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)

Specified by:

clone in interface INDArray

Overrides:

clone in class AStridedVector

Returns:

clear

public void clear()

exactClone

public GrowableVector exactClone()

Description copied from class: AVector

Returns an exact clone of this vector, i.e. of the same type

Specified by:

exactClone in interface INDArray

Specified by:

exactClone in class AVector

Returns:

validate

public void validate()

Description copied from interface: INDArray

Validates the internal data structure of the INDArray. Throws an exception on failure. Failure indicates a serious bug and/or data corruption.

Specified by:

validate in interface INDArray

Overrides:

validate in class AArrayVector
