Enum Constant Detail

AUTO

public static final CompressionFactory.LongEncodingStrategy AUTO

AUTO strategy scans all values once before encoding them. It stores the value cardinality and maximum offset of the values to determine whether to use DELTA, TABLE, or LONGS format.

LONGS

public static final CompressionFactory.LongEncodingStrategy LONGS

LONGS strategy always encode the values using LONGS format

Method Detail

values

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

Returns:

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

valueOf

public static CompressionFactory.LongEncodingStrategy 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

toString

public String toString()

Overrides:

toString in class Enum<CompressionFactory.LongEncodingStrategy>
