## Detailed Description

A sequence wrapper.

This objects holds the reference to the original sequence and also implements iObject. Basically a sequence corresponds to a series of operations that are time based and can be scheduled on the sequence manager. This class enhances iSequence with support for custom operations and parameter blocks.

Note that many parameters given to the AddOperation functions are of type iParameterESM.

Main creators of instances implementing this interface:

- iEngineSequenceManager::CreateSequence ()

Main ways to get pointers to this interface:

- iEngineSequenceManager::GetSequence()
- iEngineSequenceManager::FindSequenceByName()

Main users of this interface:

Operation: test trigger state and run a sequence if trigger is still valid or another sequence if not (both sequences can be 0 in which case nothing is run).

Use in combination with AddOperationCheckTrigger().

Parameters:

  | time | is the relative time at which this operation will fire.
  | trigger | is a parameter representing a trigger to enable or disable.

virtual iEngineSequenceParameters* iSequenceWrapper::CreateBaseParameterBlock | ( |  | ) | `[pure virtual]`

| Create a parameter block for this sequence wrapper. After creating this you can initialized the parameters (with names and optional default values). Later on you can use GetSequenceParameters() to get a copy of a parameter block to use for running a sequence.

virtual csPtr<iEngineSequenceParameters> iSequenceWrapper::CreateParameterBlock | ( |  | ) | `[pure virtual]`

Create a parameter block which you can then fill in and then give as a parameter running this sequence.

This essentially creates a copy of the base parameter block created with CreateBaseParameterBlock(). Modifications on the parameter block returned by this function have no effect on the parameter block which is kept internally. You should only set the values of the given parameter block and not create/remove variables. This function returns 0 if there is no parameter block for this sequence.

virtual iEngineSequenceParameters* iSequenceWrapper::GetBaseParameterBlock | ( |  | ) | `[pure virtual]`

| Get the pointer to the base parameter block (or 0 if there is no such block).

virtual iSequence* iSequenceWrapper::GetSequence | ( |  | ) | `[pure virtual]`

| Get the sequence that this wrapper maintains. It is allowed to use the underlying sequence for general sequence operations like adding conditions, operations, and general sequence management. The AddOperationBla() functions provided in this wrapper do nothing more than add custom operations through the regular iSequence->AddOperation().

virtual iObject* iSequenceWrapper::QueryObject | ( |  | ) | `[pure virtual]`

| Query iObject that is implemented by the sequence manager.
