protected abstract boolean eq(AbstractQuantity<Q> dq)

isZero

protected abstract boolean isZero()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

Casts this quantity to a parameterized quantity of specified nature or throw a ClassCastException if the dimension of the specified quantity and its unit's dimension do not match. For example:
Quantity length = BaseQuantity.of("2 km").asType(Length.class);

Specified by:

asType in interface javax.measure.Quantity<Q extends javax.measure.Quantity<Q>>

Parameters:

type - the quantity class identifying the nature of the measure.

Returns:

this measure parameterized with the specified type.

Throws:

ClassCastException - if the dimension of this unit is different from the specified quantity dimension.

UnsupportedOperationException - if the specified quantity class does not have a public static field named "UNIT" holding the SI unit for the quantity.
