Enum parquet.ParquetDataPageVersion

java.lang.Object

java.lang.Enum<parquet.ParquetDataPageVersion>

org.bytedeco.arrow.global.parquet.ParquetDataPageVersion

All Implemented Interfaces:

Serializable, Comparable<parquet.ParquetDataPageVersion>

Enclosing class:

parquet

@Namespace(value="parquet")
public static enum parquet.ParquetDataPageVersion
extends Enum<parquet.ParquetDataPageVersion>

Controls serialization format of data pages. parquet-format v2.0.0 introduced a new data page metadata type DataPageV2 and serialized page structure (for example, encoded levels are no longer compressed). Prior to the completion of PARQUET-457 in 2020, this library did not implement DataPageV2 correctly, so if you use the V2 data page format, you may have forward compatibility issues (older versions of the library will be unable to read the files). Note that some Parquet implementations do not implement DataPageV2 at all.

Method Detail

values

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

Returns:

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

valueOf

public static parquet.ParquetDataPageVersion 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
