Method Detail

values

public static FileUpload.Unit[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (FileUpload.Unit c : FileUpload.Unit.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static FileUpload.Unit valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getFactor

public long getFactor()

the factor to multiply with to get the number of bytes per whole unit

Returns:

the factor

format

public String format(long size,
                     NumberFormat format)

Formats the given size using a NumberFormat

Parameters:

size - the size in bytes

format - the NumberFormat

Returns:

the formatted size

format(FileUpload.Unit, long, NumberFormat)

format

public static String format(FileUpload.Unit unit,
                            long size,
                            NumberFormat format)

Formats the given size of the given FileUpload.Unit using a NumberFormat, appending the given FileUpload.Unit.
Example:

 NumberFormat numberFormat = new DecimalFormat("0.0# ", new DecimalFormatSymbols(Locale.ENGLISH));
 String format = Unit.format(Unit.MB, (long) (2.46d * 1024l * 1024l), numberFormat);
 org.junit.Assert.assertEquals("2.46 MB", format);
 
 

Parameters:

unit - the FileUpload.Unit

size - the size in bytes

format - the NumberFormat

Returns:

the formatted size
