Enum Constant Detail

INSERT

public static final TableWriter.InsertMode INSERT

insert rows whose key do not exist, ignore the others

UPSERT

public static final TableWriter.InsertMode UPSERT

insert rows as they come, overwriting old values if the key already exist

INSERT_APPEND

public static final TableWriter.InsertMode INSERT_APPEND

like INSERT but if the row already exist, append to it all the columns that are not already there

UPSERT_APPEND

public static final TableWriter.InsertMode UPSERT_APPEND

like INSERT_APPEND but if the row already exists, add all the columns from the new row, overwriting old values if necessary

LOAD

public static final TableWriter.InsertMode LOAD

like INSERT but do not update histograms.

used for bulk load when we know that the data cannot be in the table

Method Detail

values

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

Returns:

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

valueOf

public static TableWriter.InsertMode 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
