Description

A composite of display conditions combined using a Binary Logic Operation. For example, several Time Interval Display Condition objects can be added to a composite. The composite can then be assigned to an object so the object is only rendered when the current animation time is within one of the time intervals.

Object Model

Public Methods

Add	Adds a display condition to the end of the composite.
AddWithNegate	Adds a display condition to the end of the composite.
Clear	Removes all display conditions from the composite.
GetNegate	Determines if a logical `not` operation is applied to a display condition in the composite.
GetNegateAt	Determines if a logical `not` operation is applied to a display condition in the composite.
Insert	Inserts a display condition at the given zero-based index, shifting existing display conditions.
InsertWithNegate	Inserts a display condition at the given zero-based index, shifting existing display conditions.
Remove	Removes a display condition from the composite.
RemoveAt	Removes the display condition at the given zero-based index, shifting existing display conditions.
Reserve	Requests enough memory for the composite to contain at least count display conditions. Count will not be affected but Capacity may be.
SetNegate	Sets if a logical `not` operation is applied to a display condition in the composite when the composite is evaluated.
SetNegateAt	Sets if a logical `not` operation is applied to a display condition in the composite when the composite is evaluated.

Public Properties

Capacity	Gets the number of display conditions for which memory has been allocated. This will always be greater or equal to Count.
Count	Gets the number of display conditions in the composite.
Item	Returns the condition at the given zero-based index.
LogicOperation	Gets or sets the binary logic operation applied to all display conditions in the composite when the composite is evaluated. To combine logical `and` and `or` operations in the same expression, create composites containing composites.
