Method Detail

values

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

Returns:

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

valueOf

public static PageCodecMarker 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

isSet

public boolean isSet(byte value)

set

public byte set(byte value)

unset

public byte unset(byte value)

none

public static byte none()

The byte value of no PageCodecMarker values set to true

toSummaryString

public static String toSummaryString(byte markers)
