Method Detail

values

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

Returns:

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

valueOf

public static Operator 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

getValue

public int getValue()

Get the integer value that is used when storing an operator in the database.

getSymbol

public String getSymbol()

Get the symbol for this operator, useful for display in client applications.

getSqlSymbol

public String getSqlSymbol()

Get the SQL symbol for this operator. This can be used when creating SQL/HQL queries.

isExpressionOperator

public boolean isExpressionOperator()

getRestriction

public abstract Restriction getRestriction(Expression lvalue,
                                           Expression rvalue)
                                    throws InvalidDataException

Throws:

InvalidDataException

fromValue

public static Operator fromValue(int value)

Get the Operator object when you know the integer code.
