All Implemented Interfaces:

Serializable, Comparable<ColStatsProcessor.ColumnStatsType>

Enclosing class:

ColStatsProcessor

public static enum ColStatsProcessor.ColumnStatsType
extends Enum<ColStatsProcessor.ColumnStatsType>

Enumeration of column stats type. Each Hive primitive type maps into a single column stats type, e.g., byte, short, int, and bigint types map into long column type. Each column stats type has _n_ column stats fields associated with it.

Method Detail

values

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

Returns:

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

valueOf

public static ColStatsProcessor.ColumnStatsType 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
