Class VarCharVector.Mutator

java.lang.Object

org.apache.arrow.vector.BaseValueVector.BaseMutator

org.apache.arrow.vector.VarCharVector.Mutator

All Implemented Interfaces:

ValueVector.Mutator, VariableWidthVector.VariableWidthMutator

Enclosing class:

VarCharVector

public final class VarCharVector.Mutator
extends BaseValueVector.BaseMutator
implements VariableWidthVector.VariableWidthMutator

MutableVarChar implements a vector of variable width values. Elements in the vector are accessed by position from the logical start of the vector. A fixed width offsetVector is used to convert an element's position to it's offset from the start of the (0-based) ArrowBuf. Size is inferred by adjacent elements. The width of each element is 4 byte(s) The equivalent Java primitive is 'int' NB: this class is automatically generated from ValueVectorTypes.tdd using FreeMarker.
