public TagValidator()

Method Details

preMissingItem

public boolean preMissingItem(DbControl dc,
 OverviewContext context,
 Node parentNode)

If the parent item has a subtype that is related to a TAG subtype, report the missing item as a Validator.MISSING_TAG failure. Otherwise, ignore the missing tag.

Specified by:

preMissingItem in interface NodeValidator<Tag>

Overrides:

preMissingItem in class BasicNodeValidator<Tag>

Parameters:

dc - A DbControl to use if the validation needs to access the database

context - The current overview context

parentNode - The parent node that is missing the item

Returns:

Always false

postValidate

public void postValidate(DbControl dc,
 OverviewContext context,
 Node node,
 Node parentNode)

Checks if the tag is of the correct subtype.

Specified by:

postValidate in interface NodeValidator<Tag>

Overrides:

postValidate in class NameableNodeValidator<Tag>

Parameters:

dc - A DbControl to use if the validation needs to access the database

context - The current overview context

node - The node object that represents item

parentNode - The parent node that is linked with the item

getMissingItemFix

protected Fix getMissingItemFix(DbControl dc,
 Node parentNode)

Description copied from class: BasicNodeValidator

Subclasses should override this method if they have a suggessted fix for a missing item problem. The default implementation does nothing, but the following template may be usable by most subclasses:

                new Fix("Add item to parent", parentNode.getItem())
                

Specified by:

getMissingItemFix in class BasicNodeValidator<Tag>

Returns:

Suggested fix is to add a tag to the parent item

getExpectedTagSubtype

protected ItemSubtype getExpectedTagSubtype(DbControl dc,
 BasicItem parentItem)

Get the subtype of the associated tag that we expect for the given parent item.
