Class ValueBinder<R> (6.74.0) 

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
Returns
Type Description
R

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.
