#### Defined in
client/v2/algod/models/types.ts:5119
___
### scratchChanges
• `Optional` **scratchChanges**: [`ScratchChange`](modelsv2.ScratchChange.md)[]
The writes into scratch slots.
#### Defined in
client/v2/algod/models/types.ts:5124
___
### spawnedInners
• `Optional` **spawnedInners**: (`number` \| `bigint`)[]
The indexes of the traces for inner transactions spawned by this opcode, if any.
#### Defined in
client/v2/algod/models/types.ts:5129
___
### stackAdditions
• `Optional` **stackAdditions**: [`AvmValue`](modelsv2.AvmValue.md)[]
The values added by this opcode to the stack.
#### Defined in
client/v2/algod/models/types.ts:5134
___
### stackPopCount
• `Optional` **stackPopCount**: `number` \| `bigint`

___
### stateChanges
• `Optional` **stateChanges**: [`ApplicationStateOperation`](modelsv2.ApplicationStateOperation.md)[]

## Methods
### get\_obj\_for\_encoding
▸ **get_obj_for_encoding**(`binary?`): `Record`\<`string`, `any`\>
Get an object ready for encoding to either JSON or msgpack.
#### Parameters
| Name | Type | Default value | Description |
| :------ | :------ | :------ | :------ |
| `binary` | `boolean` | `false` | Use true to indicate that the encoding can handle raw binary objects (Uint8Arrays). Use false to indicate that raw binary objects should be converted to base64 strings. True should be used for objects that will be encoded with msgpack, and false should be used for objects that will be encoded with JSON. |
#### Returns
`Record`\<`string`, `any`\>
#### Inherited from
BaseModel.get\_obj\_for\_encoding
#### Defined in
client/v2/basemodel.ts:65
___
### from\_obj\_for\_encoding
▸ `Static` **from_obj_for_encoding**(`data`): [`SimulationOpcodeTraceUnit`](modelsv2.SimulationOpcodeTraceUnit.md)
#### Parameters
| Name | Type |
| :------ | :------ |
| `data` | `Record`\<`string`, `any`\> |
#### Returns
