Parameter Name Description elementType Type
Returns bool()
public static Type bool () Returns the descriptor for the BOOL type.
Returns bytes()
public static Type bytes () Returns the descriptor for the BYTES type: a variable-length byte string.
Returns date()
public static Type date () Returns the descriptor for the DATE type: a timezone independent date in the range [0001-01-01, 9999-12-31).
Returns equals(Object o)
public boolean equals ( Object o ) Parameter Returns Overrides float64()

Returns numeric()
public static Type numeric () Returns the descriptor for the NUMERIC type.
Returns string()
public static Type string () Returns the descriptor for the STRING type: a variable-length Unicode character string.
