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(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

symbol

public String symbol()

Returns:

symbol

isOuter

public boolean isOuter()

Check if this join type is an outer join.

Returns:

true if left/right/full outer, or false otherwise

toString

public String toString()

Overrides:

toString in class Enum<JoinType>

See Also:

Enum.toString()

forSymbol

public static JoinType forSymbol(String symbol)

Attempt to find the JoinType given a symbol. The matching is done independent of case.

Parameters:

symbol - the symbol

Returns:

the JoinType having the supplied symbol, or null if there is no JoinType with the supplied symbol

Throws:

IllegalArgumentException - if the symbol is null

getString

public String getString()

Get the string representation of this query object.

Specified by:

getString in interface Readable

Returns:

the string representation; never null
