Method Detail

getPattern

public String getPattern()

Yields the underlying format pattern.

Returns:

String

getType

public Class<U> getType()

Yields the associated reified unit type.

Returns:

Class

format

public String format(TimeSpan<? super U> duration)

Creates a textual output of given duration.

Parameters:

duration - duration object

Returns:

textual representation of duration

Throws:

IllegalArgumentException - if some aspects of duration prevents printing (for example too many nanoseconds)

print

public void print(TimeSpan<? super U> duration,
                  Appendable buffer)
           throws IOException

Creates a textual output of given duration and writes to the buffer.

Parameters:

duration - duration object

buffer - I/O-buffer where the result is written to

Throws:

IllegalArgumentException - if some aspects of duration prevents printing (for example too many nanoseconds)

IOException - if writing into buffer fails

parse

public S parse(CharSequence text)
        throws ParseException

Equivalent to parse(text, 0).

Parameters:

text - custom textual representation to be parsed

Returns:

parsed duration

Throws:

ParseException - (for example in case of mixed signs or if trailing unparsed characters exist)

parse

public S parse(CharSequence text,
               int offset)
        throws ParseException

Analyzes given text according to format pattern and parses the text to a duration.

Parameters:

text - custom textual representation to be parsed

offset - start position for the parser

Returns:

parsed duration

Throws:

ParseException - (for example in case of mixed signs or if trailing unparsed characters exist)
