Enum Constant Summary

Enum Constants

Enum Constant	Description
APPROXIMATION	If a good, and secure estimate is needed (the actual number can be lower or higher).
EXACT	If the exact number is needed.
FAST_APPROXIMATION	If a rough estimate is needed (the actual number can be lower or higher).

Method Summary

Modifier and Type	Method	Description
static Result.SizePrecision	valueOf(String name)	Returns the enum constant of this type with the specified name.

Enum Constant Detail

EXACT

public static final Result.SizePrecision EXACT

If the exact number is needed.

APPROXIMATION

public static final Result.SizePrecision APPROXIMATION

If a good, and secure estimate is needed (the actual number can be lower or higher). This is supposed to be faster than exact count, but slower than a fast approximation.

FAST_APPROXIMATION

public static final Result.SizePrecision FAST_APPROXIMATION

If a rough estimate is needed (the actual number can be lower or higher). This is supposed to be faster than a good approximation. It could be (for example) the expected cost of the query.

Method Detail

values

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

Returns:

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

valueOf

public static Result.SizePrecision 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
