public final class Type implements Serializable
Describes a type in the Cloud Spanner type system. Types can either be primitive (for example,
INT64 and STRING) or composite (for example, ARRAY<INT64> or
STRUCT<INT64,STRING>).
Type instances are immutable.
Static Methods
array(Type elementType)
public static Type array(Type elementType)
Returns a descriptor for an array of elementType.

Returns
bool()
public static Type bool()
Returns the descriptor for the BOOL type.
bytes()
public static Type bytes()
Returns the descriptor for the BYTES type: a variable-length byte string.
date()
public static Type date()

[0001-01-01, 9999-12-31).
float64()
public static Type float64()
Returns the descriptor for the FLOAT64 type: a floating point type with the same value
domain as a Java {code double}.
int64()
public static Type int64()
