Constructor Details

DoubleVector

public DoubleVector(double[] data)

Creates a double vector.

Parameters:

data - the backing values

Method Details

data

public double[] data()

Returns the value of the data record component.

Returns:

the value of the data record component

getType

public @NonNull Class<? extends Number> getType()

Return the primitive number type the vector is backed by.

Specified by:

getType in interface Vector

Returns:

the primitive number type (Byte.TYPE, Float.TYPE or Double.TYPE)

toFloatArray

public float[] toFloatArray()

Convert this vector to a new float array copy.

Specified by:

toFloatArray in interface Vector

Returns:

a new float[] with the vector content

toDoubleArray

public double[] toDoubleArray()

Convert this vector to a new double array copy.

Specified by:

toDoubleArray in interface Vector

Returns:

a new double[] with the vector content

toByteArray

public byte[] toByteArray()

Convert this vector to a new byte array copy.

Specified by:

toByteArray in interface Vector

Returns:

a new byte[] with the vector content

toString

public @NonNull String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

obj - the object with which to compare

Returns:

true if this object is the same as the obj argument; false otherwise.
