Interface Unit<U extends Unit<U>>

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

Data, Duration, Money, Occurrence

public interface Unit<U extends Unit<U>>
extends java.io.Serializable

Represents a generic unit of measurement. Any measurable unit for Rating can be represented by the Unit interface. Each Unit has a symbol like "sec" - if measuring duration or "KB" - if measuring data volume and an internal symbol table. The symbol table assists in local conversion between supported units like a factor of 1000 if it is a millisecond to second and 1024 between Bytes and KiloBytes.

Method Detail

getRatio

@Deprecated
long getRatio(U u)
                   throws Unit.UnitMisMatchException

Deprecated.

NOTE: for backward compatibility, actually obsolete Deprecated, use convert instead The method returns the ratio of numeric conversion between the this and the passed unit. The method throws Unit.UnitMisMatchException if ratio between the two units is not supported.

Parameters:

u - Unit

Returns:

long the ratio between the two Units.

Throws:

Unit.UnitMisMatchException - If ration cannot be obtained between two Units.

valueOf

UnitValue<U> valueOf(java.math.BigDecimal b)

Returns an instance of the UnitValue with this Unit and provided quantity

Parameters:

b - BigDecimal

Returns:

UnitValue

convert

UnitValue<U> convert(UnitValue<U> otherValue)

Returns an instance of the UnitValue with this Unit converted according to a specific ratio

Parameters:

otherValue - UnitValue unit value to convert to

Returns:

UnitValue unit value resulting from conversion of otherValue to the unit
