Enum Constant Detail

INNER

public static final JoinType INNER
Inner JOIN.


LEFT_OUTER

public static final JoinType LEFT_OUTER
Left outer JOIN.


RIGHT_OUTER

public static final JoinType RIGHT_OUTER
Right outer JOIN.


FULL_OUTER

Method Detail

values

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

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

valueOf

public static JoinType valueOf(java.lang.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:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
java.lang.NullPointerException - if the argument is null

getType

public static final JoinType getType(int identifier)
Translate an integer to a JOIN type.

Parameters:
identifier - The native ID defined in the C++ AEJoinType enum. The ordinals of the JoinType enum in Java are all 1 equal to those in C++.
Returns:
A corresponding object of this class.
