Method Detail

format

public abstract Appendable format(javax.measure.Quantity<?> quantity,
                                  Appendable dest)
                           throws IOException

Formats the specified quantity into an Appendable.

Specified by:

format in interface javax.measure.format.QuantityFormat

Parameters:

quantity - the quantity to format.

dest - the appendable destination.

Returns:

the specified Appendable.

Throws:

IOException - if an I/O exception occurs.

parse

public abstract javax.measure.Quantity<?> parse(CharSequence csq,
                                                ParsePosition cursor)
                                         throws IllegalArgumentException,
                                                javax.measure.format.MeasurementParseException

Parses a portion of the specified CharSequence from the specified position to produce an object. If parsing succeeds, then the index of the cursor argument is updated to the index after the last character used.

Specified by:

parse in interface javax.measure.format.QuantityFormat

Parameters:

csq - the CharSequence to parse.

cursor - the cursor holding the current parsing index.

Returns:

the object parsed from the specified character sub-sequence.

Throws:

IllegalArgumentException - if any problem occurs while parsing the specified character sequence (e.g. illegal syntax).

javax.measure.format.MeasurementParseException

parse

public abstract javax.measure.Quantity<?> parse(CharSequence csq)
                                         throws javax.measure.format.MeasurementParseException

Parses a portion of the specified CharSequence from the specified position to produce an object. If parsing succeeds, then the index of the cursor argument is updated to the index after the last character used.

Specified by:

parse in interface javax.measure.format.QuantityFormat

Specified by:

parse in interface tech.uom.lib.common.function.Parser<CharSequence,javax.measure.Quantity>

Parameters:

csq - the CharSequence to parse.

Returns:

the object parsed from the specified character sub-sequence.

Throws:

IllegalArgumentException - if any problem occurs while parsing the specified character sequence (e.g. illegal syntax).

javax.measure.format.MeasurementParseException

parse

protected abstract javax.measure.Quantity<?> parse(CharSequence csq,
                                                   int index)
                                            throws IllegalArgumentException,
                                                   javax.measure.format.MeasurementParseException

Parses a portion of the specified CharSequence from the specified position to produce an object. If parsing succeeds, then the index of the cursor argument is updated to the index after the last character used.

Parameters:

csq - the CharSequence to parse.

index - the current parsing index.

Returns:

the object parsed from the specified character sub-sequence.

Throws:

IllegalArgumentException - if any problem occurs while parsing the specified character sequence (e.g. illegal syntax).

javax.measure.format.MeasurementParseException

format

public final StringBuffer format(Object obj,
                                 StringBuffer toAppendTo,
                                 FieldPosition pos)

Specified by:

format in class Format

parseObject

public final javax.measure.Quantity<?> parseObject(String source,
                                                   ParsePosition pos)

Specified by:

parseObject in class Format

format

public final String format(javax.measure.Quantity<?> quantity)

Formats an object to produce a string. This is equivalent to

format(unit, new StringBuilder()).toString();

Specified by:

format in interface javax.measure.format.QuantityFormat

Parameters:

quantity - The quantity to format

Returns:

Formatted string.

format

protected final StringBuffer format(ComparableQuantity<?> quantity,
                                    StringBuffer dest)

Convenience method equivalent to #format(ComparableQuantity, Appendable) except it does not raise an IOException.

Parameters:

quantity - the quantity to format.

dest - the appendable destination.

Returns:

the specified StringBuilder.

formatMixed

protected abstract StringBuffer formatMixed(MixedQuantity<?> mixed,
                                            StringBuffer dest)

Convenience method equivalent to #format(MixedQuantity, Appendable) except it does not raise an IOException.

Parameters:

mixed - the mixed quantity to format.

dest - the appendable destination.

Returns:

the specified StringBuilder.

formatCompound

protected abstract StringBuffer formatCompound(CompoundQuantity<?> comp,
                                               StringBuffer dest)

Deprecated. use #formatMixed

Convenience method equivalent to #format(CompoundQuantity, Appendable) except it does not raise an IOException.

Parameters:

comp - the composite quantity to format.

dest - the appendable destination.

Returns:

the specified StringBuilder.
