```
@Nullable
BitmapColumnIndex forValue(@Nonnull
                           Object value,
                           TypeSignature<ValueType> valueType)
```
    Get a BitmapColumnIndex which can compute the ImmutableBitmap corresponding to rows matching the supplied value. Generates an empty bitmap when passed a value that doesn't exist. May return null if a value index cannot be computed for the supplied value type.
    Does not match null, use NullValueIndex for matching nulls.
    
    Parameters:
    
    value - value to match
    
    valueType - type of the value to match, used to assist conversion from the match value type to the column value type
    
    Returns:
    
    ImmutableBitmap corresponding to the rows which match the value, or null if an index connot be computed for the supplied value type
