Enum Constant Detail

UNCOMPRESSED

public static final PointEncoders UNCOMPRESSED

Denotes the uncompressed point encoding / decoding method.

COMPRESSED

public static final PointEncoders COMPRESSED

Denotes the compressed point encoding / decoding method.

Method Detail

values

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

Returns:

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

valueOf

public static PointEncoders 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

getEncoding

public byte getEncoding()

Returns the encoding of this point encoder. It is 0x02 for COMPRESSED and 0x04 for UNCOMPRESSED.

Returns:

the encoding as byte

getDefaultPointEncoder

public static PointEncoders getDefaultPointEncoder()

Gets the default point encoding algorithm identifier.

Returns:

the default point encoding algorithm identifier

See Also:

setDefaultPointEncoder(PointEncoders)

setDefaultPointEncoder

public static void setDefaultPointEncoder(PointEncoders defaultPointEncoder)

Sets the default point encoding algorithm identifier.

Parameters:

defaultPointEncoder - the default encoding algorithm identifier

See Also:

getDefaultPointEncoder()

getSupportedEncodings

public static byte getSupportedEncodings()

Returns all supported compression algorithms.

Returns:

one of the defined encoding values or a combination of them
