Constructor Details

Angle

Angle(double value)

Parameters:

value - Value in turns.

Method Details

getAsDouble

public double getAsDouble()

Specified by:

getAsDouble in interface DoubleSupplier

Returns:

the value.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object other)

Test for equality with another object. Objects are considered to be equal if their concrete types are equal and their values are exactly the same (or both are Double.NaN).

Overrides:

equals in class Object

Parameters:

other - Object to test for equality with this instance.

Returns:

true if the objects are equal, false if other is null, not of the same type as this instance, or not equal to this instance.

toTurn

public abstract Angle.Turn toTurn()

Convert to a Angle.Turn.

Returns:

the angle in turns.

toRad

public abstract Angle.Rad toRad()

Convert to a Angle.Rad.

Returns:

the angle in radians.

toDeg

public abstract Angle.Deg toDeg()

Convert to a Angle.Deg.

Returns:

the angle in degrees.
