Constructor Detail

DateRefinement

public DateRefinement(java.util.List<Refinement.Clause<java.util.Calendar>> clauses,
                      int count)

Constructs a DateRefinement with a List of clauses and a count.

Parameters:

clauses - the List off Refinement.Clause objects to be used in this Refinement.

count - the number of results expected when this DateRefinement is applied

DateRefinement

public DateRefinement(java.util.Calendar date,
                      int count)

Constructs a DateRefinement with one single Calendar value and the number of times that Calendar value shows up.

Parameters:

date - the Calendar value based on which an EQUALS clause is built

count - the number of results expected when this DateRefinement is applied

Method Detail

initClauses

protected java.util.List<Refinement.Clause<java.util.Calendar>> initClauses(java.util.Calendar value,
                                                                            java.lang.String comparator)

Overrides:

initClauses in class Refinement<java.util.Calendar>

isAccumulative

public boolean isAccumulative()

Is this refinement accumulative over another refinement?

setAccumulative

public void setAccumulative(boolean value)

Set the accumulative characteristic of this refinement

setCalendarType

public void setCalendarType(int value)

Set calendar type

Parameters:

value - Calendar field constant

isYearly

public boolean isYearly()

Is calendar type yearly?

isMonthly

public boolean isMonthly()

Is calendar type monthly?

isDaily

public boolean isDaily()

Is calendar type daily?

isSinceNumDays

public boolean isSinceNumDays()

Is calender type since num days?

getYear

public java.util.Calendar getYear()

If refinement is a yearly refinement, return a calendar object of the year.

createPredicate

protected AttributePredicate<java.util.Calendar> createPredicate(QName name,
                                                                 java.lang.String comparator,
                                                                 java.util.Calendar value)

Overrides:

createPredicate in class Refinement<java.util.Calendar>

buildName

protected void buildName(java.util.Calendar calendar)

Builds the name of the DateRefinement with a Calendar by formatting it and setting the name to be that String value.

Specified by:

buildName in class Refinement<java.util.Calendar>

Parameters:

calendar - the Calendar value to use to build the name

getConjunctionOp

public ComplexPredicate.ConjunctionOp getConjunctionOp()

Returns the conjunction operator for this DateRefinement.

Specified by:

getConjunctionOp in class Refinement<java.util.Calendar>

Returns:

a ConjunctionOp value that is either an And or an Or.

addAttributePredicate

protected void addAttributePredicate(java.util.List<Predicate> children,
                                     AttributePredicate<java.util.Calendar> newPredicate)
                              throws ContradictionException

Adds an attribute predicate to the list of Predicate objects held within a top-level ComplexPredicate. The assumption on the top-level ComplexPredicate is that it serves only one Refiner and therefore in this case, we only care about the DateRefiner.

Overrides:

addAttributePredicate in class Refinement<java.util.Calendar>

Parameters:

children - a List of child Predicates coming from a ComplexPredicate dedicated to a DateRefiner.

newPredicate - the new Predicate to be added to the list of child Predicates.

Throws:

ContradictionException

hasMatch

public final boolean hasMatch(java.util.Calendar value)

Returns whether the calendar value passed in matches the criteria held in this Refinement.

Specified by:

hasMatch in class Refinement<java.util.Calendar>

Parameters:

value - the Calendar value to be matched.

Returns:

true if the value falls within the range defined by this Refinement.

hasMatch

public static final boolean hasMatch(java.util.Calendar value,
                                     java.lang.String comparator,
                                     java.util.Calendar clauseValue)

Matches a Calendar value with a criterion made up of a comparator and another Calendar.

Parameters:

value - the value to compare

comparator - the comparator to use

clauseValue - the value to compare against

Returns:

true if the value compares positively with the comparator and the clause value.

getNumDaysAsCalendar

public static final java.util.Calendar getNumDaysAsCalendar(int num)

Get Calendar object for operand of SinceNumDays comparator

Parameters:

num - number of days

Returns:

Calendar representing the operand of SinceNumDays comparator

getCalendarSinceNumDays

public static final java.util.Calendar getCalendarSinceNumDays(java.util.Calendar cal)

Get Calendar object for query execution of SinceNumDays comparator

Parameters:

cal - representing the operand of SinceNumDays comparator

Returns:

Calendar representing the calendar for SinceNumDays comparator

getNumDays

public static final int getNumDays(java.util.Date date)

Get number of days from Date object of operand of SinceNumDays comparator

Parameters:

date - Date object of operand of SinceNumDays comparator

int - value of NumDays
