Interface RepeatedVariableWidthVectorLike

public interface RepeatedVariableWidthVectorLike

A ValueVector mix-in that can be used in conjunction with variable RepeatedValueVector subtypes (e.g. Strings, Lists, etc).

Method Summary

Modifier and Type	Method and Description
void	allocateNew(int totalBytes, int parentValueCount, int childValueCount) Allocate a new memory space for this vector.
int	getByteCapacity() Provide the maximum amount of variable width bytes that can be stored int his vector.

Method Detail

allocateNew

void allocateNew(int totalBytes,
                 int parentValueCount,
                 int childValueCount)

Allocate a new memory space for this vector. Must be called prior to using the ValueVector.

Parameters:

totalBytes - Desired size of the underlying data buffer.

parentValueCount - Number of separate repeating groupings.

childValueCount - Number of supported values in the vector.

getByteCapacity

int getByteCapacity()

Provide the maximum amount of variable width bytes that can be stored int his vector.

Returns:

the byte capacity
