Examples of Mutation

com.google.collide.dto.Mutation
Dual use. Used by clients to request tree mutations on the server, and broadcast by the server to inform clients about mutations that happened.
com.sleepycat.persist.evolve.Mutation
The base class for all mutations. @see com.sleepycat.persist.evolve Class Evolution @author Mark Hayes
jfun.yan.Mutation
To represent any mutation to an object or any side effect.

org.apache.accumulo.core.data.Mutation

Mutation represents an action that manipulates a row in a table. A mutation holds a list of column/value pairs that represent an atomic set of modifications to make to a row.
Convenience methods which takes columns and value as CharSequence (String implements CharSequence) are provided. CharSequence is converted to UTF-8 by constructing a new Text object.
When always passing in the same data as a CharSequence/String, its probably more efficient to call the Text put methods. This way the data is only encoded once and only one Text object is created.
All of the put methods append data to the mutation, they do not overwrite anything that was previously put. The mutation holds a list of all column/values that were put into it. The putDelete() methods do not remove something that was previously added to the mutation, rather they indicate that Accumulo should insert a delete marker for that row column.
org.apache.cassandra.avro.Mutation
org.apache.cassandra.db.Mutation
org.apache.cassandra.hadoop.avro.Mutation
org.apache.cassandra.thrift.Mutation
A Mutation is either an insert, represented by filling column_or_supercolumn, or a deletion, represented by filling the deletion attribute. @param column_or_supercolumn. An insert to a column or supercolumn @param deletion. A deletion of a column or supercolumn
org.apache.hadoop.hbase.client.Mutation
org.apache.hadoop.hbase.thrift.generated.Mutation
A Mutation object is used to either update or delete a column-value.
