Method Detail

appendValue

public final DateSource appendValue(java.util.Date appendValue)
Appends the specified Date object to this DateSource.
Parameters:
appendValue - The Date to append to this DateSource.
Returns:
A DateSource that has the same elements as this DateSource with an appended element that has the specified Date as its value.

appendValues

public final DateSource appendValues(java.util.Date[] appendValues)
Appends the specified Date objects to this DateSource.
Parameters:
appendValues - An array of Date objects to append to this DateSource.
Returns:
A DateSource that has the same elements as this DateSource with appended elements that have the specified Date objects as values.

eq

public final BooleanSource eq(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value and determines they are equal.
Parameters:
rhs - The Date value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element that has a value of true when the value of the corresponding element of this DateSource equals the specified Date value, or false when it does not.

ge

public final BooleanSource ge(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value, and determines whether it has a greater or equal value. The BooleanSource returned by this method has an element that is true when the value of a given element of this DateSource is greater than or equal to the specified Date value, or a value of false when it is not.
Parameters:
rhs - The Date value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element with a value of true when the value of a given element of this DateSource is greater than or equal to the specified Date value, or false when it is not.

getDataType

public Source getDataType()
Gets the fundamental Source that represents the OLAP Java API data type of this DateSource, which is Date.
Overrides:
getDataType in class Source
Returns:
The fundamental Source that represents the OLAP Java API Date data type.

gt

public final BooleanSource gt(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value, and determines whether it has a greater value.
Parameters:
rhs - The Date value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element with a value of true when the value of the corresponding element of this DateSource is greater than the specified Date value, or false when it is not.

le

public final BooleanSource le(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value, and determines whether it has a lesser or equal value.
Parameters:
rhs - The boolean value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element with a value of true when the value of the corresponding element of this DateSource is less than or equal to the specified Date value, or false when it is not.

lt

public final BooleanSource lt(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value, and determines whether it has a lesser value.
Parameters:
rhs - The Date value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element with a value of true when the value of a given element of this DateSource is less than the specified Date value, or false when it is not.

ne

public final BooleanSource ne(java.util.Date rhs)
Compares the value of each element of this DateSource to the specified Date value, and determines whether it is not equal to the value.
Parameters:
rhs - The Date value that you want to compare to the values of the elements of this DateSource.
Returns:
A BooleanSource that has an element with a value of true when the value of a given element of this DateSource is not equal to the specified Date value, or false when it is equal to the specified value.

plusDays

public final DateSource plusDays(int rhs)
Adds the specified number of days to the value of each element of this DateSource. For example, the following code creates a DateSource, aDate, and then adds five days to the value of aDate. The dp object is the DataProvider.
 // Get an instance of a java.util.Calendar object.
 Calendar calendar =  Calendar.getInstance();
 // Set the date and time for the Calendar object.
 calendar.set(2009, 6, 17, 14, 24, 23);
 // Get a java.util.Date object from the Calendar object.
 Date date = calendar.getTime();
 // Create a DateSource using the Date object.
 DateSource aDate = dp.createConstantSource(date);
 DateSource aDatePlus5 = aDate.plusDays(5);
If the value of aDate is Fri Jul 17 19:24:23 GMT-05:00 2009, then the value of aDatePlus5 is Wed Jul 22 19:24:23 GMT-05:00 2009.
