validate

public final List<ValidationWarnings.WarningsGroup> validate(List<ICalComponent> hierarchy)

Checks the component for data consistency problems or deviations from the spec. These problems will not prevent the component from being written to a data stream, but may prevent it from being parsed correctly by the consuming application. These problems can largely be avoided by reading the Javadocs of the component class, or by being familiar with the iCalendar standard.

Parameters:

hierarchy - the hierarchy of components that the component belongs to

Returns:

a list of warnings or an empty list if no problems were found

ICalendar.validate()

validate

protected void validate(List<ICalComponent> components,
                        List<String> warnings)

Checks the component for data consistency problems or deviations from the spec. Meant to be overridden by child classes.

Parameters:

components - the hierarchy of components that the component belongs to

warnings - the list to add the warnings to

checkRequiredCardinality

protected void checkRequiredCardinality(List<String> warnings,
                                        Class<? extends ICalProperty>... classes)

Utility method for validating that there is exactly one instance of each of the given properties.

Parameters:

warnings - the list to add the warnings to

classes - the properties to check

checkOptionalCardinality

protected void checkOptionalCardinality(List<String> warnings,
                                        Class<? extends ICalProperty>... classes)

Utility method for validating that there is no more than one instance of each of the given properties.

Parameters:

warnings - the list to add the warnings to

classes - the properties to check
