public final class Identifier

  1. Object
  2. Identifier
Immutable composite identity, in the model’s declared identifier-field order.

Methods

public static Identifier of(Object... values)Creates a composite identifier, normalizing scalar storage representations.
public Object[] values()Returns a copy of the normalized key component array.
public boolean equals(Object other)Compares normalized components in identifier-field order.
public int hashCode()Computes a hash from the normalized key components.

Inherited methods

Method details

of

public static Identifier of(Object... values)
Creates a composite identifier, normalizing scalar storage representations. Integral byte, short, and int values compare as longs. Copies the supplied array; components should be immutable. Binary components are unsupported.

Parameters

values Object...
key components in declared identifier-field order

Returns

composite identifier for session lookup

Throws

IllegalArgumentException
if a component is binary

values

public Object[] values()
Returns a copy of the normalized key component array.

Returns

components in identifier-field order

equals

public boolean equals(Object other)
Compares normalized components in identifier-field order.

Parameters

other Object
object to compare

Returns

true if the other identifier has equal components

hashCode

public int hashCode()
Computes a hash from the normalized key components.

Returns

component-based hash code
