Class ValueBinder<R>

java.lang.Object

com.google.cloud.spanner.ValueBinder<R>

public abstract class ValueBinder<R>
extends Object

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.
