Constructor and Description
BooleanDataType(String name, boolean primitive) Constructor for a boolean datatype (either a primitive boolean type or the Boolean class).

Method Summary

Modifier and Type	Method and Description
protected Boolean	cast(Object value, Cloud cloud, Node node, Field field) Cast a bit more conservatively, because Casting aggressively casts everything to boolean, which would make nearly every value valid.
protected <D> D	preCast(D value, Cloud cloud, Node node, Field field) This method implements 'precasting', which can be seen as a kind of datatype specific casting.

Constructor Detail

BooleanDataType

public BooleanDataType(String name,
                       boolean primitive)

Constructor for a boolean datatype (either a primitive boolean type or the Boolean class).

Parameters:

name - the name of the data type

primitive - indicate if a primitive type should be used

Method Detail

preCast

protected <D> D preCast(D value,
                        Cloud cloud,
                        Node node,
                        Field field)

Description copied from class: BasicDataType

This method implements 'precasting', which can be seen as a kind of datatype specific casting. It should anticipate that every argument can be null. It should not change the actual type of the value.

Overrides:

preCast in class BasicDataType<Boolean>

cast

protected final Boolean cast(Object value,
                             Cloud cloud,
                             Node node,
                             Field field)
                      throws CastException

Cast a bit more conservatively, because Casting aggressively casts everything to boolean, which would make nearly every value valid.

Overrides:

cast in class BasicDataType<Boolean>

Throws:

CastException
