Static 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.
