UpdateContext Class Reference

---

Detailed Description

This object represents the operator update context. It gives access to the operator and the evaluation time. The UpdateContext is only valid within the context of the Update() function for operators that are based on a Preset and SPDL. Self-Installed CustomOperators use the OperatorContext object instead.

Member Function Documentation

bool IsA

(

siClassID

in_ClassID

)

const [virtual]

Returns true if a given class type is compatible with this API class.

Parameters:

in_ClassID

class type.

Returns:

true if the class is compatible, false otherwise.

Reimplemented from SIObject.

siClassID GetClassID

(

)

const [virtual]

Returns the type of the API class.

Returns:

The class type.

Reimplemented from SIObject.

UpdateContext& operator=

(

const UpdateContext &

in_obj

)

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

in_obj

constant class object.

Returns:

The new UpdateContext object.

UpdateContext& operator=

(

const CRef &

in_ref

)

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

in_ref

constant class object.

Returns:

The new UpdateContext object.

Reimplemented from SIObject.

Operator GetOperator

(

)

Returns the Operator object for the update context.

Returns:

The current Operator.

double GetCurrentFrame

(

)

Returns the time in frames at which the Operator is being evaluated.

Returns:

Time (frame) at which the Operator is being evaluated.

CValue GetUserData

(

)

Returns the user data stored in the UpdateContext.

Returns:

The user data.

CStatus PutUserData

(

const CValue &

in_val

)

Sets user data which is passed to the compiled scripted operator from evaluation to evaluation.

Parameters:

in_val

user data to be set for the operator instance.

Returns:

CStatus::OK success

CStatus::Fail failure.
