Method Detail

values

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

Returns:

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

valueOf

public static LM.LockType 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

isCompatible

public boolean isCompatible(LM.LockType current)

check whether current lock type is compatible with this lock type

Parameters:

current - type of lock currently held

Returns:

true if the two locks are compatible.

conflicts

public boolean conflicts(LM.LockType current)

check whether current lock type conflicts to this lock type

Parameters:

current - type of lock currently held

Returns:

true if the two locks conflicts.

subsume

public boolean subsume(LM.LockType other)

check whether this lock type subsumes (is stronger) other lock type

Parameters:

other -

Returns:

true if this lock type is stronger than other
