Enum Constant Detail

INDEXED

public static final ParamType INDEXED

Indexed values to be passed to the statement in order. In JDBC, this is used for statements that use ? as a placeholder for parameters.

NAMED

public static final ParamType NAMED

Named values to be passed to the statement by name. Unless the underlying database directly supports named parameters, we use :name in the statement text to represent a named parameter.

UNKNOWN

public static final ParamType UNKNOWN

Statement type is not known.

Method Detail

values

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

Returns:

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

valueOf

public static ParamType 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
