Method Detail

isEquivalentOf

boolean isEquivalentOf(javax.measure.Unit<Q> that)

Compares two instances of , doing the conversion of unit if necessary.

Parameters:

that - the Unit<Q> to be compared with this instance.

Returns:

true if that < this.

Throws:

NullPointerException - if the unit is null

isSystemUnit

boolean isSystemUnit()

Indicates if this unit belongs to the set of coherent SI units (unscaled SI units). The base and coherent derived units of the SI form a coherent set, designated the set of coherent SI units. The word coherent is used here in the following sense: when coherent units are used, equations between the numerical values of quantities take exactly the same form as the equations between the quantities themselves. Thus if only units from a coherent set are used, conversion factors between units are never required.

Returns:

equals(toSystemUnit())
