Interface Mutation.SimpleBuilder

All Known Implementing Classes:

SimpleBuilders.MutationBuilder

Enclosing class:

Mutation

public static interface Mutation.SimpleBuilder

Interface for building mutations geared towards human.

This should generally not be used when performance matters too much, but provides a more convenient interface to build a mutation than using the class constructor when performance is not of the utmost importance.

Method Summary

Modifier and Type	Method and Description
Mutation	build() Build the mutation represented by this builder.
Mutation.SimpleBuilder	timestamp(long timestamp) Sets the timestamp to use for the following additions to this builder or any derived (update or row) builder.
Mutation.SimpleBuilder	ttl(int ttl) Sets the ttl to use for the following additions to this builder or any derived (update or row) builder.
PartitionUpdate.SimpleBuilder	update(java.lang.String tableName) Adds an update for table identified by the provided name and return a builder for that partition.
PartitionUpdate.SimpleBuilder	update(TableMetadata metadata) Adds an update for table identified by the provided metadata and return a builder for that partition.

Method Detail

timestamp

Mutation.SimpleBuilder timestamp(long timestamp)

Sets the timestamp to use for the following additions to this builder or any derived (update or row) builder.

Parameters:

timestamp - the timestamp to use for following additions. If that timestamp hasn't been set, the current time in microseconds will be used.

Returns:

this builder.

ttl

Mutation.SimpleBuilder ttl(int ttl)

Sets the ttl to use for the following additions to this builder or any derived (update or row) builder.

Note that the for non-compact tables, this method must be called before any column addition for this ttl to be used for the row LivenessInfo.

Parameters:

ttl - the ttl to use for following additions. If that ttl hasn't been set, no ttl will be used.

Returns:

this builder.

update

PartitionUpdate.SimpleBuilder update(TableMetadata metadata)

Adds an update for table identified by the provided metadata and return a builder for that partition.

Parameters:

metadata - the metadata of the table for which to add an update.

Returns:

a builder for the partition identified by metadata (and the partition key for which this is a mutation of).

update

PartitionUpdate.SimpleBuilder update(java.lang.String tableName)

Adds an update for table identified by the provided name and return a builder for that partition.

Parameters:

tableName - the name of the table for which to add an update.

Returns:

a builder for the partition identified by metadata (and the partition key for which this is a mutation of).

build

Mutation build()

Build the mutation represented by this builder.

Returns:

the built mutation.
