Mutation (Google Cloud 0.89.0-alpha API)

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 Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`static Mutation`	`create()` Creates new instance of Mutation object.
`static Mutation`	`createUnsafe()` Creates new instance of Mutation object which allows setCell operation to use server side timestamp.
`Mutation`	`deleteCells(String familyName, ByteString qualifier)` Adds a mutation which deletes cells from the specified column.
`Mutation`	`deleteCells(String familyName, ByteString qualifier, Range.TimestampRange timestampRange)` Adds a mutation which deletes cells from the specified column, restricted to a given timestamp range.
`Mutation`	`deleteCells(String familyName, String qualifier)` Adds a mutation which deletes cells from the specified column.
`Mutation`	`deleteFamily(String familyName)` Adds a mutation which deletes all cells from the specified column family.
`Mutation`	`deleteRow()` Adds a mutation which deletes all cells from the containing row.
`static Mutation`	`fromProtoUnsafe(List<com.google.bigtable.v2.Mutation> protos)` Wraps the List of protobuf `Mutation`.
`Mutation`	`setCell(String familyName, ByteString qualifier, ByteString value)` Adds a mutation which sets the value of the specified cell.
`Mutation`	`setCell(String familyName, ByteString qualifier, long timestamp, ByteString value)` Adds a mutation which sets the value of the specified cell.
`Mutation`	`setCell(String familyName, String qualifier, long timestamp, String value)` Adds a mutation which sets the value of the specified cell.
`Mutation`	`setCell(String familyName, String qualifier, String value)` Adds a mutation which sets the value of the specified cell.

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.

fromProtoUnsafe
```
@BetaApi
public static Mutation fromProtoUnsafe(List<com.google.bigtable.v2.Mutation> protos)
```
Wraps the List of protobuf Mutation. This methods, like createUnsafe(), 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.
