Method Detail

convertMsDuration

public static javax.xml.datatype.Duration convertMsDuration(int milliseconds)

Converts a duration value in milliseconds to an Duration instance.

Parameters:

milliseconds - the number of milliseconds to convert.

Returns:

the Duration instance or null if the conversion fails.

convertDuration

public static javax.xml.datatype.Duration convertDuration(byte[] value)

Checks if the value is of the form mm:ss or if it is a milliseconds value and returns a Duration instance.

Parameters:

value - the byte array to convert.

Returns:

the Duration instance or null if the conversion fails.

convertMinSecDuration

public static javax.xml.datatype.Duration convertMinSecDuration(byte[] minSec)

Converts a duration value of the form mm:ss to an Duration instance.

Parameters:

minSec - the byte array containing the duration value.

Returns:

the Duration instance or null if the conversion fails.

convertDate

public static javax.xml.datatype.XMLGregorianCalendar convertDate(java.util.Date date)

Converts a date value to an XMLGregorianCalendar instance.

Parameters:

date - the Date value to convert.

Returns:

the XMLGregorianCalendar instance or null if the conversion fails.

fireDateEvents

public static void fireDateEvents(NewFSParser parser,
                                  Metadata meta,
                                  java.io.File file)
                           throws java.io.IOException

Writes the date values of the file to the parser.

Parameters:

parser - the NewFSParser instance to fire NewFSParser.metaEvent(Metadata) events.

meta - the metadata item to use.

file - the file to read time values from.

Throws:

java.io.IOException - if any error occurs while writing to the parser.

checkUTF

public static byte[] checkUTF(byte[] data)

Checks if the given byte array only contains valid UTF-8 characters. All invalid chars are replaced by spaces.

Parameters:

data - the byte array to check.

Returns:

a byte array containing only valid UTF-8 chars.
