Class PVector2D.Builder<T>

java.lang.Object

com.io7m.jtensors.core.parameterized.vectors.PVector2D.Builder<T>

Enclosing class:

PVector2D<T>

public static final class PVector2D.Builder<T>
extends Object

Builds instances of type PVector2D. Initialize attributes and then invoke the build() method to create an immutable instance.

Builder is not thread-safe and generally should not be stored in a field or collection, but instead used immediately to create instances.

Method Summary

Modifier and Type	Method and Description
