Class VarCharVector.BufferedMutator

java.lang.Object

org.apache.drill.exec.vector.VarCharVector.BufferedMutator

Enclosing class:

VarCharVector

public static final class VarCharVector.BufferedMutator
extends Object

Helper class to buffer container mutation as a means to optimize native memory copy operations. Ideally, this should be done transparently as part of the Mutator and Accessor APIs. NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.
