Enum Constant Detail

OFFSET

public static final PageLocation._Fields OFFSET

Offset of the page in the file *

COMPRESSED_PAGE_SIZE

public static final PageLocation._Fields COMPRESSED_PAGE_SIZE

Size of the page, including header. Sum of compressed_page_size and header length

FIRST_ROW_INDEX

public static final PageLocation._Fields FIRST_ROW_INDEX

Index within the RowGroup of the first row of the page; this means pages change on record boundaries (r = 0).

Method Detail

values

public static PageLocation._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 (PageLocation._Fields c : PageLocation._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 PageLocation._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 PageLocation._Fields findByThriftId(int fieldId)

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

findByThriftIdOrThrow

public static PageLocation._Fields findByThriftIdOrThrow(int fieldId)

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

findByName

public static PageLocation._Fields findByName(String name)

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