Enum Constant Detail

NEVER

public static final EqualsAndHashCode.CacheStrategy NEVER

Never cache. Perform the calculation every time the method is called.

LAZY

public static final EqualsAndHashCode.CacheStrategy LAZY

Cache the result of the first invocation of hashCode and use it for subsequent invocations. This can improve performance if all fields used for calculating the hashCode are immutable and thus every invocation of hashCode will always return the same value. Do not use this if there's any chance that different invocations of hashCode might return different values.

Method Detail

values

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

Returns:

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

valueOf

public static EqualsAndHashCode.CacheStrategy 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
