Interface VarLenBulkEntry

public interface VarLenBulkEntry

A bulk input entry enables us to process potentially multiple VL values in one shot (especially for very small values); please refer to org.apache.drill.exec.vector.VarBinaryVector.BulkInput.

Format -

• data: [<val1><val2><val3>..]
• value lengths: [<val1-len><val2-len><val3-len>..]

NOTE - Bulk entries are immutable

Method Detail

getTotalLength

int getTotalLength()

Returns:

total length of this bulk entry data

getDataStartOffset

int getDataStartOffset()

Returns:

data start offset

arrayBacked

boolean arrayBacked()

Returns:

true if this entry's data is backed by an array

getArrayData

byte[] getArrayData()

Returns:

byte buffer containing the data; the data is located within buffer[start-offset, length-1] where buffer is the byte array returned by this method

getData

DrillBuf getData()

Returns:

DrillBuf containing the data; the data is located within [start-offset, length-1]

getValuesLength

int[] getValuesLength()

Returns:

length table (one per VL value)

getNumValues

int getNumValues()

Returns:

number of values (including null values)

getNumNonNullValues

int getNumNonNullValues()

Returns:

number of non-null values

hasNulls

boolean hasNulls()

Returns:

true if this bulk entry has nulls; false otherwise
