Method Detail

values

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

Returns:

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

valueOf

public static FSEditLogOpCodes 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

getOpCode

public byte getOpCode()

return the byte value of the enum

Returns:

the byte value of the enum

getOpClass

public java.lang.Class<? extends FSEditLogOp> getOpClass()

fromByte

public static FSEditLogOpCodes fromByte(byte opCode)

Converts byte to FSEditLogOpCodes enum value

Parameters:

opCode - get enum for this opCode

Returns:

enum with byte value of opCode
