## Detailed Description

An interface for passing on parameters to the engine sequence manager.

You can create a ready-made instance of this interface by calling iSequenceWrapper->CreateBaseParameterBlock(). This will create an empty parameter block that specifies the supported parameters (and optional default values) that are relevant for that sequence. When running a sequence later you can call iSequenceWrapper->CreateParameterBlock() to make a clone of the base parameter block and then fill in the values.
To use a value from this parameter block you can call CreateParameterESM() which will return a parameter that you can give to an operation.

Main creators of instances implementing this interface:

- iSequenceWrapper::CreateBaseParameterBlock()
- iSequenceWrapper::CreateParameterBlock ()

Main ways to get pointers to this interface:

- iSequenceWrapper::GetBaseParameterBlock ()
- iSequenceTrigger::GetParameters ()

Main users of this interface:

- iSequenceWrapper

## Member Function Documentation

virtual void iEngineSequenceParameters::AddParameter | ( | const char * | name,
|  | iBase * | def_value = `0`
| ) | `[pure virtual]`

| Add a parameter. Warning! ONLY call this for setting up the base parameter block. Don't use this to set the values for parameters later on blocks created with CreateParameterBlock()!

virtual csPtr<iParameterESM> iEngineSequenceParameters::CreateParameterESM | ( | const char * | name | ) | `[pure virtual]`

| Create a parameter ESM which keeps a reference to this parameter block and knows how to resolve the specified parameter. Returns 0 if the parameter 'name' is not known in this block. You can use the return of this function to give as an argument for operations.

virtual iBase* iEngineSequenceParameters::GetParameter | ( | const char * | name | ) | const`[pure virtual]`

| Get a parameter by name.

virtual iBase* iEngineSequenceParameters::GetParameter | ( | size_t | idx | ) | const`[pure virtual]`

| Get a parameter.

virtual size_t iEngineSequenceParameters::GetParameterCount | ( |  | ) | const`[pure virtual]`

| Get the number of parameters supported.

virtual size_t iEngineSequenceParameters::GetParameterIdx | ( | const char * | name | ) | const`[pure virtual]`

| Get a parameter index by name.

virtual const char* iEngineSequenceParameters::GetParameterName | ( | size_t | idx | ) | const`[pure virtual]`

| Get parameter name.

virtual void iEngineSequenceParameters::SetParameter | ( | const char * | name,
|  | iBase * | value
| ) | `[pure virtual]`

| Set a parameter by name.

virtual void iEngineSequenceParameters::SetParameter | ( | size_t | idx,
|  | iBase * | value
| ) | `[pure virtual]`

| Set a parameter by index.
