◆ ~InstanceObject()

~InstanceObject ( )

Member Function Documentation

◆ Alloc()

static InstanceObject* Alloc ( )

Allocates a ObjectInstance object. Destroy the allocated ObjectInstance object with Free(). Use AutoAlloc to automate the allocation and destruction based on scope.

The allocated ObjectInstance object, or nullptr if the allocation failed.

◆ Free()

static void Free ( InstanceObject *&  bl)

Destructs ObjectInstance objects allocated with Alloc(). Use AutoAlloc to automate the allocation and destruction based on scope.

[in,out]blThe ObjectInstance object to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆ UpdateInstanceList()

static void UpdateInstanceList ( BaseObject pObj,
InstanceObjectList *  pCurrent,
InstanceObjectList *&  pList,
const Matrix m,
const void *  instanceCRC = nullptr 

Update pCurrent data with the given information, added to the list if one is provided.

[in]pObjObject used for the instance.
[in]pCurrentData structure to fill up.
[in,out]pListOptional List, pCurrent is added to the list if provided.
[in]mMatrix to use for this instance.
[in]instanceCRCUnique pointer used for CRC (used for multi-instance).

◆ RecurseGenList()

static void RecurseGenList ( BaseObject op,
BaseObject generator,
HierarchyHelp hh = nullptr 

Add op and its children as a dependency to the generator.

[in]opBaseObject the generator depends on.
[in]generatorGenerator to add the dependencies to.
[in]hhOptional HierarchyHelp.

◆ AddCacheInstanceData()

maxon::Result<void> AddCacheInstanceData ( InstanceObjectList *&  pList)

Update the instance list with the cached instance data.

[in,out]pListCurrent list to fill if provided. If null, a new list may be returned.

◆ GetReferenceObject()

BaseObject* GetReferenceObject ( BaseDocument doc) const

Return the pointer to the BaseObject being instanciated. Same as accessing the INSTANCEOBJECT_LINK element in the BaseContainer.

[in]docThe current document.
Object being instanciated. Will be null if this instance object is unassigned.

◆ SetReferenceObject()

maxon::Result<void> SetReferenceObject ( BaseObject refObj)

Set the reference object used for the multiple instances (INSTANCEOBJECT_LINK in BaseContainer).

[in]refObjdesired reference object.

◆ IsMultiInstance()

Bool IsMultiInstance ( ) const

Return whether this InstanceObject is in multi-instance mode.

True if in multi-instance mode.

◆ SetInstanceMatrices()

maxon::Result<void> SetInstanceMatrices ( const maxon::BaseArray< Matrix > &  matrices)

Set matrices for the instance(s). The array size determines the instance count.

[in]matricesInstance matrix array.

◆ GetInstanceMatrices()

const maxon::BaseArray<Matrix>* GetInstanceMatrices ( ) const

Returns an array of matrices with one element for each instance.

Pointer to the matrix array. Owned by the InstanceObject.

◆ GetInstanceMatrix()

Matrix GetInstanceMatrix ( UInt  index) const

Return the global matrix of the instance at the specified index.

[in]indexInstance index.
Instance matrix.

◆ SetInstanceMatrix()

maxon::Result<void> SetInstanceMatrix ( UInt  index,
const Matrix globalMatrix 

Set the global matrix of the instance at the specified index. index must be valid, there is no allocation for index out of range.

[in]indexInstance index.
[in]globalMatrixInstance matrix.

◆ GetMatrixDirtyID()

UInt32 GetMatrixDirtyID ( UInt  index) const

Return the Matrix dirtyID of the instance at the specified index.

[in]indexInstance index.
dirty ID.

◆ GetInstanceCount()

UInt GetInstanceCount ( ) const

Return the multi-instance count (number of instances and matrices).

Multi-instance count.

◆ SetInstanceColors()

maxon::Result<void> SetInstanceColors ( const maxon::BaseArray< maxon::Color64 > &  colors)

Set colors for the instances. Colors will be clamped between 0 and 1.

[in]colorsArray of instance colors.

◆ GetInstanceColors()

const maxon::BaseArray<maxon::Color64>* GetInstanceColors ( ) const

Return an array of instance colors. If the array is null or empty, the default color is used.

Pointer to the color array. Owned by the InstanceObject.

◆ GetInstanceColor()

maxon::Color64 GetInstanceColor ( UInt  index) const

Return the color of the instance at the specified index. If no custom color is found or the index is invalid, the default color is returned.

[in]indexInstance index.
Instance color.

◆ SetInstanceUniqueIPs()

maxon::Result<void> SetInstanceUniqueIPs ( const maxon::BaseArray< Int32 > &  uniqueIPs)

Pointer to the unique IP array. Owned by the InstanceObject.

◆ GetInstanceUniqueIP()

Int32 GetInstanceUniqueIP ( UInt  index) const

Return the unique IP of the instance at the specified index. If no unique IP is found or the index is invalid, 0 is returned.

[in]indexInstance index.
Instance unique IP.

◆ GetInstancePersistentHashes()

maxon::Block<const maxon::UniqueHash> GetInstancePersistentHashes ( ) const

Return a block of persistent hashes. These allow to uniquely identify instances over time. If the block is empty, persistent hashes aren't supported, in that case you have to use GetInstanceUniqueIPs().

Block of instances hashes.
