convertToDouble

public QualifiedValues<Double> convertToDouble()
                                        throws ValueConverters.ConversionException

Converts this object's values to Double. This a equivalent to this.convertTo(Double.class).

Returns:

this object, with all its values converted to Double.

Throws:

ValueConverters.ConversionException - if the value could not be converted to a double. Note that this may happen even if isNumeric() is True: converting a rational with a denominator equal to zero throw a ConversionException.

isNumeric()

isNA

public boolean isNA()

Tells if all values are NA.

Returns:

true if all values are NA, false otherwise.

rawValues

public List<T> rawValues()

Returns the list of the QualifiedValue-s' values.

Returns:

the list of values stored in this object's QualifiedValue-s

getValuesTypes

public List<Type> getValuesTypes()

Return the list of types of the values.

Returns:

the list of types of this object's values.

See Also:

Type.of(Object)

isNumeric

public boolean isNumeric()

Tells if all values are numeric.

Returns:

true if all values are numeric, false otherwise.

convertToDouble()

checkConversion

public <U> void checkConversion(Class<U> clazz)
                         throws ValueConverters.ConversionException

Checks that the conversion can be done on all of the object's QualifiedValue, but do not modify these values.

Type Parameters:

U - the class to which the value should be converted

Parameters:

clazz - the class to which the value should be converted

Throws:

ValueConverters.ConversionException - raised if the conversion cannot be done

See Also:

convertTo(Class)

convertTo

public <U> QualifiedValues<U> convertTo(Class<U> clazz)
                                 throws ValueConverters.ConversionException

Converts this object's values to the specified type. If the conversion cannot be done, ConversionException is raised, and the values are left untouched.

Type Parameters:

U - class of the converted values

Parameters:

clazz - the class of the converted values

Returns:

this object

Throws:

ValueConverters.ConversionException - if at least one element could not be converted
