Field Detail

fullName

public final String fullName

Full name of this storage unit. Like Megabyte for MB.

bits

public final long bits

Amount of bits represented by this storage unit.

bytes

public final float bytes

Amount of bytes (bits / 8) represented by this storage unit.

Method Detail

values

public static Storage.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 (Storage.Unit c : Storage.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 Storage.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

formatBits

public float formatBits(long bits)

Formats the given amount of bits to format specific for this storage unit.

For example, Unit.MB.formatBits(8388608) will result in 1 which can be printed as 1 MB.

Parameters:

bits - The amount of bits to format to this storage unit's representative value.

Returns:

Formatted representative value of this storage unit for the given amount of bits.

See Also:

formatBytes(long)

formatBytes

public float formatBytes(long bytes)

Formats the given amount of bytes to format specific for this storage unit.

For example, Unit.MB.formatBytes(1048576) will result in 1 which can be printed as 1 MB.

Parameters:

bytes - The amount of bytes to format to this storage unit's representative value.

Returns:

Formatted representative value of this storage unit for the given amount of bytes.
