Class Mutation

java.lang.Object

com.google.cloud.bigtable.data.v2.models.Mutation

All Implemented Interfaces:

MutationApi<Mutation>, Serializable

public final class Mutation
extends Object
implements MutationApi<Mutation>, Serializable

The concrete implementation of MutationApi that can be used to create and represent a list of mutations. It used by RowMutation and ConditionalRowMutation to encapsulate a list of mutations that will to be applied to a single row.

Method Detail

create

public static Mutation create()

Creates new instance of Mutation object.

createUnsafe

@BetaApi
public static Mutation createUnsafe()

Creates new instance of Mutation object which allows setCell operation to use server side timestamp. This is dangerous because mutations will no longer be idempotent, which might cause multiple duplicate values to be stored in Bigtable. This option should only be used for advanced usecases with extreme care.

setCell

public Mutation setCell(@Nonnull
                        String familyName,
                        @Nonnull
                        String qualifier,
                        @Nonnull
                        String value)

Description copied from interface: MutationApi

Adds a mutation which sets the value of the specified cell.

This a convenience method that converts Strings to ByteStrings and uses microseconds since epoch as the timestamp.
