Enum Constant Detail

CREATE_NEVER

public static final BigQueryIO.Write.CreateDisposition CREATE_NEVER

Specifics that tables should not be created.

If the output table does not exist, the write fails.

CREATE_IF_NEEDED

public static final BigQueryIO.Write.CreateDisposition CREATE_IF_NEEDED

Specifies that tables should be created if needed. This is the default behavior.

Requires that a table schema is provided via BigQueryIO.Write.withSchema(com.google.api.services.bigquery.model.TableSchema). This precondition is checked before starting a job. The schema is not required to match an existing table's schema.

When this transformation is executed, if the output table does not exist, the table is created from the provided schema. Note that even if the table exists, it may be recreated if necessary when paired with a BigQueryIO.Write.WriteDisposition.WRITE_TRUNCATE.

Method Detail

values

public static BigQueryIO.Write.CreateDisposition[] 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 (BigQueryIO.Write.CreateDisposition c : BigQueryIO.Write.CreateDisposition.values())
    System.out.println(c);

Returns:

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

valueOf

public static BigQueryIO.Write.CreateDisposition 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
