Method Detail

getField

public static GradientField getField(int parameters)

Get the field for number of free parameters.

Parameters:

parameters - number of free parameters

Returns:

cached field

getOne

public Gradient getOne()

Get the multiplicative identity of the field.

The multiplicative identity is the element e₁ of the field such that for all elements a of the field, the equalities a × e₁ = e₁ × a = a hold.

Specified by:

getOne in interface Field<Gradient>

Returns:

multiplicative identity of the field

getZero

public Gradient getZero()

Get the additive identity of the field.

The additive identity is the element e₀ of the field such that for all elements a of the field, the equalities a + e₀ = e₀ + a = a hold.

Specified by:

getZero in interface Field<Gradient>

Returns:

additive identity of the field

getRuntimeClass

public Class<? extends FieldElement<Gradient>> getRuntimeClass()

Returns the runtime class of the FieldElement.

Specified by:

getRuntimeClass in interface Field<Gradient>

Returns:

The Class object that represents the runtime class of this object.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
