public enum TableFieldTypeEnum
extends java.lang.Enum<TableFieldTypeEnum>

Enum class that defines values corresponding to each of the enum values defined in FieldDef.Type; which represent the possible field types of a KV Store table. The methods of this enum provide a mechanism for mapping a table defined in a given KV Store and a table created in Hive.

Method Detail

values

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

Returns:

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

valueOf

public static TableFieldTypeEnum valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

fromKvType

public static TableFieldTypeEnum fromKvType(FieldDef.Type kvType)

Maps the given field type of a KV Store table to the corresponding enum value defined in this class; corresponding to a field type of a KV Store table.

fromHiveType

public static TableFieldTypeEnum fromHiveType(TypeInfo hiveType)

Maps the given Hive column type to the corresponding enum value defined in this class; corresponding to a field type of a KV Store table. Note that some of the Hive types have no corresponding type; in which case, TABLE_FIELD_UNKNOWN_TYPE is returned.

fromHiveType

public static TableFieldTypeEnum fromHiveType(TypeInfo hiveType,
                                              FieldDef.Type kvType)

stringToEnumValue

public static TableFieldTypeEnum stringToEnumValue(java.lang.String str)

kvHiveTypesMatch

public static boolean kvHiveTypesMatch(FieldDef kvFieldDef,
                                       TypeInfo hiveColumnType)
