public abstract class ValueBinder<R>
An interface for binding a Value in some context. Users of the Cloud Spanner client
library never create a ValueBinder
directly; instead this interface is returned from
other parts of the library involved in Value
construction. For example, Mutation.WriteBuilder#set(String) returns a binder to bind a column value, and
Statement#bind(String)
returns a binder to bind a parameter to a value.
ValueBinder
subclasses typically carry state and are therefore not thread-safe,
although the core implementation itself is thread-safe.

Methods
to(boolean value)
public R to(boolean value)
Binds to Value.bool(value)
Parameter |
---|
Name | Description |
value | boolean
|
to(ByteArray value)
public R to(ByteArray value)
Binds to Value.bytes(value)
. Use #to(Value) in combination with Value#bytesFromBase64(String) if you already have the value that you want to bind in base64
format. This prevents unnecessary decoding and encoding of base64 strings.
