Method Details

init

void init(io.airlift.slice.Slice input)

readNext

int readNext(boolean[] values,
 int offset,
 int length)

Populate 'values' with true for nulls and return the number of non-nulls encountered. 'values' array is assumed to be empty at the start of reading a batch, i.e. contain only false values.

skip

int skip(int length)

Skip 'length' values and return the number of non-nulls encountered

getFlatDefinitionLevelDecoder

static FlatDefinitionLevelDecoder getFlatDefinitionLevelDecoder(int maxDefinitionLevel)
