Constructor Details

ComplexField

private ComplexField()

Private constructor for the singleton.

Method Details

getInstance

public static ComplexField getInstance()

Get the unique instance.

Returns:

the unique instance

getOne

public Complex 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<Complex>

Returns:

multiplicative identity of the field

getZero

public Complex 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<Complex>

Returns:

additive identity of the field

getRuntimeClass

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

Returns the runtime class of the FieldElement.

Specified by:

getRuntimeClass in interface Field<Complex>

Returns:

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

readResolve

private Object readResolve()

Handle deserialization of the singleton.

Returns:

the singleton instance
