Google BigQuery Table Field Value class. Objects of this class represent values of a BigQuery Table Field. A list of values forms a table row. Tables rows can be gotten as the result of a query or when listing table data.
Implements
SerializableStatic Methods
of(FieldValue.Attribute attribute, Object value)
public static FieldValue of(FieldValue.Attribute attribute, Object value)
Creates an instance of FieldValue
, useful for testing.
If the attribute
is Attribute#PRIMITIVE, the value
should be the
string representation of the underlying value, eg "123"
for number 123
.
If the attribute
is Attribute#REPEATED or Attribute#RECORD, the
value
should be List
of FieldValues or FieldValueList,
respectively.
This method is unstable. See this discussion for more context.
