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
.

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(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 nameNullPointerException
- if the argument is null
