DSIntermediateResultUnit

The IntermediateResultUnit class represents the base structure for units of intermediate results in image processing. This class acts as a base and contains common methods shared by all intermediate result units.

@interface DSIntermediateResultUnit : NSObject

class IntermediateResultUnit : NSObject

Methods

Method	Description
`getHashId`	Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit.
`getOriginalImageHashId`	Gets the hash ID of the original image associated with this unit.
`getOriginalImageTag`	Gets the tag associated with the original image.
`getType`	Gets the type of the intermediate result unit, defined by the enumeration `IntermediateResultUnitType`.
`getTransformMatrix`	Gets the transformation matrix via `DSTransformMatrixType`.
`clone`	Creates a copy of the intermediate result unit.
`replace`	Replaces the content of the intermediate result unit.

getHashId

Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit.

Objective-C
Swift

```
-(NSString*)getHashId;
```
```
func getHashId() -> String
```

getOriginalImageHashId

Gets the hash ID of the original image associated with this unit. You can use this ID to get the original image via DSIntermediateResultManager class.

Objective-C
Swift

```
-(NSString*)getOriginalImageHashId;
```

func getOriginalImageHashId() -> String

getOriginalImageTag

Gets the tag associated with the original image.

Objective-C
Swift

-(nullable DSImageTag*)getOriginalImageTag;

func getOriginalImageTag() -> ImageTag?

Return Value

The image tag of the original image.

getType

Gets the type of the intermediate result unit, defined by the enumeration DSIntermediateResultUnitType.

Objective-C
Swift

-(DSIntermediateResultUnitType)getType;

func getType() -> IntermediateResultUnitType

Return Value

The type of the intermediate result unit.

getTransformMatrix

Gets the transformation matrix via DSTransformMatrixType.

Objective-C
Swift

-(CGAffineTransform)getTransformMatrix:(DSTransformMatrixType)type;

func getTransformMatrix(_ type: TransformMatrixType) -> CGAffineTransform

Parameters

[in] matrixType: The transform matrix type.

Return Value

The corresponding transformation matrices are as follows:

local image to original image
original image to local image
rotated image to original image
original image to rotated image

clone

Creates a copy of the intermediate result unit.

Objective-C
Swift

```
- (DSIntermediateResultUnit*)clone;
```
```
func clone() -> IntermediateResultUnit
```

Return Value

A copy of the intermediate result unit.

replace

Replaces the content of the intermediate result unit.

Objective-C
Swift

- (NSInteger)replace:(DSIntermediateResultUnit*)oldUnit;

func replace(_ oldUnit: IntermediateResultUnit) -> NSInteger

Parameters

[in] oldUnit: The old unit.

Return Value

A NSInteger that indicates whether the replace is success. If success returns 0, otherwise returns the error code.
