Method Detail

values

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

Returns:

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

valueOf

public static AccessHint 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

getValue

public byte getValue()

Returns the byte value of the enumerations value.

Returns:

byte representation

getAccessHint

public static AccessHint getAccessHint(byte byteIdentifier)

Get the AccessHint enumeration value by passing the byte identifier to this method.

Parameters:

byteIdentifier - of AccessHint.

Returns:

AccessHint instance.

Throws:

java.lang.IllegalArgumentException - if the access hint for the byteIdentifier cannot be found
