#include <c4d_fielddata.h>

Detailed Description

The full result from sampling a field. Struct own the sampled data if it is not a sub block of the full sample. FieldOutput used as subblock don't own the memory and don't carry a ref count on the allocated memory, hence the real block must stay valid during the use of a subblock.

Constructor & Destructor Documentation

◆ FieldOutput() [1/2]

FieldOutput ( )

default

Creates and empty sample.

◆ FieldOutput() [2/2]

FieldOutput ( FieldOutput && moveRef )

Move construction. Takes ownership of the sample memory.

Parameters

[in] moveRef The source sample.

◆ ~FieldOutput()

~FieldOutput ( )

Frees sample memory if not a sub block.

Member Function Documentation

◆ MAXON_OPERATOR_MOVE_ASSIGNMENT()

MAXON_OPERATOR_MOVE_ASSIGNMENT ( FieldOutput )

◆ operator FieldOutputBlock()

operator FieldOutputBlock ( ) const

Casting operator, equivalent to GetBlock().

Returns: A sub block for the whole FieldOutput.

◆ GetBlock()

FieldOutputBlock GetBlock ( ) const

Gets the total arrays in a FieldOutputBlock.

Returns: A sub block for the whole FieldOutput.

◆ GetSubBlock()

maxon::Result<FieldOutputBlock> GetSubBlock	(	Int	offset,
		Int	blockSize = `FIELD_EXECUTION_BLOCK_SIZE`
	)		const

Gets a sub-section of the total arrays.

Parameters

[in]	offset	The offset index to retrieve a sub-block starting at.
[in]	blockSize	Suggested size of the block, will be clamped against the maximum number of entries.

Returns: The sub block.

◆ Reset()

void Reset ( )

Resets the FieldOutput to an empty state. All memory will be deallocated.

◆ Flush()

void Flush ( )

Flush the FieldOutput content, keeping the arrays allocated for future resize.

◆ GetCount()

Int GetCount ( void ) const

Gets the number of elements in the FieldOutput

Returns: The count.

◆ IsValid()

Bool IsValid ( ) const

Checks if the FieldOutput allocations and sizes are valid (empty FieldOutput is considered valid).

◆ IsPopulated()

Bool IsPopulated ( ) const

Checks if the FieldOutput is valid and non-empty.

◆ IsEqual()

Bool IsEqual ( const FieldOutput & comp ) const

Compares the content of both FieldOutput. Count and array content must be the same.

Parameters

[in] comp Source for the comparison.

Returns: True if equal.

◆ CopyFrom()

maxon::Result<void> CopyFrom ( const FieldOutput & src )

Copies from the FieldOutput described by src. Performs a deep copy.

Parameters

[in] src Source for the duplication.

Returns: OK on success.

◆ CopyArrayContentFrom() [1/2]

maxon::Result<void> CopyArrayContentFrom ( const FieldOutput & src )

Copies from the FieldOutput array content from src. Size and flags will not be affected by this action. Source data content will be copied into target up to current size. If target is bigger than source, the remaining items are cleared.

Parameters

[in] src Source for the duplication.

Returns: OK on success.

◆ CopyArrayContentFrom() [2/2]

maxon::Result<void> CopyArrayContentFrom ( const FieldOutputBlock & src )

Copies from the FieldOutput array content from src. Size and flags will not be affected by this action. Source data content will be copied into target up to current size. If target is bigger than source, the remaining items are cleared.

Parameters

[in] src Source for the duplication.

Returns: OK on success.

◆ Resize()

maxon::Result<void> Resize	(	Int	newSize,
		FIELDSAMPLE_FLAG	sampleFlags = `FIELDSAMPLE_FLAG::ALL`,
		maxon::COLLECTION_RESIZE_FLAGS	resizeFlags = `maxon::COLLECTION_RESIZE_FLAGS::DEFAULT`
	)

Resizes the arrays held in the FieldOutput. Unspecified channel arrays will be resized to 0 length (according to resizeFlags).

Parameters

[in]	newSize	The size that the arrays should become.
[in]	sampleFlags	The channels to sample.
[in]	resizeFlags	The flags for which channels should be resized.

Returns: OK on success.

◆ ClearMemory() [1/2]

void ClearMemory	(	Bool	deactivatedOnly = `true`,
		Bool	deactivatedState = `false`
	)

Reset the sample's data to default values, optionally only the deactivated content too. Values are reset to 0, colors to 1.0, direction to 0, deactivated to 0.

Parameters

[in]	deactivatedOnly	True to deactivated only.
[in]	deactivatedState	(Optional) The state the deactivated should be cleared to

◆ ClearMemory() [2/2]

void ClearMemory	(	Int	startIdx,
		Int	count,
		Bool	deactivatedOnly,
		Bool	deactivatedState
	)

Reset the sample's data to default values, optionally only the deactivated content too. Values are reset to 0, colors to 1.0, direction to 0, deactivated to 0.

Parameters

[in]	startIdx	Array clear start index.
[in]	count	Number of array items to reset to default value.
[in]	deactivatedOnly	True to deactivated only.
[in]	deactivatedState	(Optional) The state the deactivated should be cleared to

◆ ClearDeactivated()

void ClearDeactivated ( Bool state = false )

Clears the deactivated array.

◆ CalculateCrc()

UInt32 CalculateCrc ( ) const

Calculates a crc on all internal data using maxon::Crc32C. Crc is not kept internally and will be calculated from scratch on each CalculateCrc call.

Returns: The crc.

◆ Alloc()

static maxon::Result<FieldOutput*> Alloc	(	Int	size,
		FIELDSAMPLE_FLAG	flags = `FIELDSAMPLE_FLAG::ALL`
	)

static

Allocate a heap FieldOutput with all specified sampling arrays. Equivalent of calling empty constructor followed by Resize. Use FieldOutputRef to have a scoped or auto deleted FieldOutput.

Parameters

[in]	size	The size.
[in]	flags	The flags.

Returns: A MemoryError if it fails, else a FieldOutput*.

◆ Free()

static void Free ( FieldOutput *& p )

◆ Create() [1/2]

static maxon::Result<FieldOutput> Create	(	Int	size,
		FIELDSAMPLE_FLAG	flags = `FIELDSAMPLE_FLAG::ALL`

Create a FieldOutput with all specified sampling arrays. Same as Alloc, but on the stack. Equivalent of calling empty constructor followed by Resize.

Parameters

[in]	flags	The flags.

Returns: The resulting FieldOutput.

◆ Create() [2/2]

static maxon::Result<FieldOutput> Create ( FieldOutputBlock & src )

static

Create a FieldOutput with all specified sampling arrays. Size will be fetched from the source FieldOutput. Array content will be copied from source FieldOutput. Equivalent of calling empty constructor followed by CopyFrom.

Parameters

[in] src The source FieldOutput.

Returns: The resulting FieldOutput.

MAXON_DISALLOW_COPY_AND_ASSIGN ( FieldOutput )

private
