public UInt8ColumnReader()

Method Detail

valueType

public ValueType valueType()

Description copied from interface: ScalarReader

Describe the type of the value. This is a compression of the value vector type: it describes which method will return the vector value.

Returns:

the value type which indicates which get method is valid for the column

width

public int width()

Specified by:

width in class BaseScalarReader.BaseFixedWidthReader

getLong

public long getLong()

Specified by:

getLong in interface ScalarReader

Overrides:

getLong in class AbstractScalarReader
