Enum Constant Detail

LOCAL

public static final ValidationDepth LOCAL

Perform a client-side only validation. Typically to determine whether a connection is still active or other mechanism that does not involve remote communication.

REMOTE

public static final ValidationDepth REMOTE

Perform a remote connection validations. Typically by sending a database message or some other mechanism to validate that the database connection and session are active and can be used for database queries. Any query submitted by the driver to validate the connection is executed in the context of the current transaction.

Method Detail

values

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

Returns:

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

valueOf

public static ValidationDepth 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
