Method Details

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 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 ComparableQuantity<?> parse(CharSequence csq,
 ParsePosition cursor)
                                     throws IllegalArgumentException,
javax.measure.format.ParserException

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 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.ParserException

parse

public abstract ComparableQuantity<?> parse(CharSequence csq)
                                     throws javax.measure.format.ParserException

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 tech.uom.lib.common.function.Parser<CharSequence, ComparableQuantity>

Specified by:

parse in interface 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.ParserException

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 StringBuilder format(AbstractQuantity<?> quantity,
 StringBuilder dest)

Convenience method equivalent to

invalid reference

#format(AbstractQuantity, Appendable)

except it does not raise an IOException.

Parameters:

quantity - the quantity to format.

dest - the appendable destination.

Returns:

the specified StringBuilder.
