Method Detail

values

public static NumericEncoding[] 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 (NumericEncoding c : NumericEncoding.values())
    System.out.println(c);

Returns:

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

valueOf

public static NumericEncoding valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

isBigendian

public java.lang.Boolean isBigendian()

Gives the big/little-endianness of this encoding, if that's all the work that has to be done. If the return value is non-null, then numeric values are encoded the same way that java does it (two's complement for integers and IEEE754 for floating point) with big- or little-endian byte ordering, according to the return value. Otherwise, some unspecified encoding is in operation.

Returns:

TRUE for simple big-endian, FALSE for simple little-endian, null for something weird

getEncoding

public static NumericEncoding getEncoding(int code)
                                   throws CdfFormatException

Returns the encoding corresponding to the value of the encoding field of the CDF Descriptor Record.

Parameters:

code - encoding code

Returns:

encoding object

Throws:

CdfFormatException - if code is unknown
