Enum Constant Detail

COLUMNS

public static final RowGroup._Fields COLUMNS

Metadata for each column chunk in this row group. This list must have the same order as the SchemaElement list in FileMetaData.

TOTAL_BYTE_SIZE

public static final RowGroup._Fields TOTAL_BYTE_SIZE

Total byte size of all the uncompressed column data in this row group *

NUM_ROWS

public static final RowGroup._Fields NUM_ROWS

Number of rows in this row group *

SORTING_COLUMNS

public static final RowGroup._Fields SORTING_COLUMNS

If set, specifies a sort ordering of the rows in this RowGroup. The sorting columns can be a subset of all the columns.

Method Detail

values

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

Returns:

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

valueOf

public static RowGroup._Fields 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

findByThriftId

public static RowGroup._Fields findByThriftId(int fieldId)

Find the _Fields constant that matches fieldId, or null if its not found.

findByThriftIdOrThrow

public static RowGroup._Fields findByThriftIdOrThrow(int fieldId)

Find the _Fields constant that matches fieldId, throwing an exception if it is not found.

findByName

public static RowGroup._Fields findByName(String name)

Find the _Fields constant that matches name, or null if its not found.
