Method Details

bindVector

public void bindVector(ColumnMetadata schema,
 VectorAccessor va)

Overrides:

bindVector in class BaseScalarReader

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

getDecimal

public BigDecimal getDecimal()

Specified by:

getDecimal in interface ScalarReader

Overrides:

getDecimal in class AbstractScalarReader
