Enum Constant Detail

NONE

public static final SqlOperandTypeChecker.Consistency NONE

Do not try to make arguments consistent.

COMPARE

public static final SqlOperandTypeChecker.Consistency COMPARE

Make arguments of consistent type using comparison semantics. Character values are implicitly converted to numeric, date-time, interval or boolean.

LEAST_RESTRICTIVE

public static final SqlOperandTypeChecker.Consistency LEAST_RESTRICTIVE

Convert all arguments to the least restrictive type.

Method Detail

values

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

Returns:

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

valueOf

public static SqlOperandTypeChecker.Consistency 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
