Enum Constant Detail

DENSE

public static final StorageType DENSE

Dense storage. Use Dense to store small quantities of values, or values where zero is not common, or larger access times are unacceptable, or memory availability is high.

SPARSE

public static final StorageType SPARSE

Sparse storage. Use Sparse to store large quantities of values when most are zero and larger access times are acceptable and memory availability is low. Changing a zero value to a non-zero value is CPU-time-expensive

Method Detail

values

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

Returns:

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

valueOf

public static StorageType 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
