public class DateRangeItem
extends CanvasItem

Allows a user to select an absolute or relative range of dates via two RelativeDateItems (if allowRelativeDates is true) or two DateItems.

The item's data type is expected to be one of "date" or "datetime" and dictates whether the dates in the range include a time portion. If unset and the item's form is databound, the data type is detected from the associated dataSource field. If there is no such field, or the form is not databound, the default data type value is "date".

DateRangeItem is just a convenience relative to using two RelativeDateItem or DateItem controls in a form, then using operator and criteriaField to cause them to produce a date range. If you need more control over layout, validation, event handling or any other aspect of appearance or behavior, stop using DateRangeItem and use two DateItem/RelativeDateItem controls directly instead.

setDefaultProperties

public static void setDefaultProperties(DateRangeItem dateRangeItemProperties)

Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

Parameters:

dateRangeItemProperties - properties that should be used as new defaults when instances of this class are created

setFromDate

public void setFromDate(java.util.Date fromDate)

Initial value for the "from" date. Sets the fromDate for this DateRangeItem.

Parameters:

fromDate - the date from which this item should start it's range. Default value is today

getFromDate

public java.util.Date getFromDate()

Initial value for the "from" date.

Returns:

java.util.Date

getValue

public DateRange getValue()

Retrieves the current value of this dateRangeItem. The return value is a DateRange object that excludes start and end values if they aren't set.

Overrides:

getValue in class FormItem

Returns:

the current value of this item

setValue

public void setValue(DateRange value)

Sets the value for this dateRangeItem. The value parameter is a DateRange object that optionally includes both start and end values.

Parameters:

value - the new value for this item

setCanEditCriterionPredicate

public void setCanEditCriterionPredicate(FormItemCanEditCriterionPredicate predicate)

The default canEditCriterion() predicate returns true if the specified criterion contains:

• A single "lessOrEqual" or "greaterOrEqual" criterion on this field
• An "and" type criterion containing a "lessOrEqual" and a "greaterOrEqual" criterion on this field
• A single "equals" criterion. Internally, this will be converted into a range by constructing an "and" type criterion containing both a "lessOrEqual" and a "greaterOrEqual" criterion on this field. Note that subsequent calls to the FormItemCriterionGetter's getCriterion() method will return this more complex criterion.

Overrides:

setCanEditCriterionPredicate in class CanvasItem

Parameters:

predicate - the predicate to determine the form items that can edit the criterion in question

See Also:

FormItem.setCanEditCriterionPredicate, CriteriaEditing overview and related methods

setCriterionSetter

public void setCriterionSetter(FormItemCriterionSetter setter)

The default setCriterion() implementation applies the specified criterion to this item for editing. Applies any specified "greaterOrEqual" operator criterion or sub-criterion to our fromField and any specified "lessOrEqual" operator criterion or sub-criterion to our toField.

Note that a single "equals" criterion can also be passed. See setCanEditCriterionPredicate() for more detail.

Overrides:

setCriterionSetter in class CanvasItem

Parameters:

setter - provides a method to update this field with the edited criterion
