Method Detail

values

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

Returns:

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

valueOf

public static SearchArgument.TruthValue 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

or

public SearchArgument.TruthValue or(SearchArgument.TruthValue right)

Compute logical or between the two values.

Parameters:

right - the other argument or null

Returns:

the result

and

public SearchArgument.TruthValue and(SearchArgument.TruthValue right)

Compute logical AND between the two values.

Parameters:

right - the other argument or null

Returns:

the result

not

public SearchArgument.TruthValue not()

isNeeded

public boolean isNeeded()

Does the RecordReader need to include this set of records?

Returns:

true unless none of the rows qualify
