FieldOutputBlockTemplate< CONSTBLOCK > Struct Template Reference

#include <c4d_fielddata.h>

Detailed Description

template<Bool CONSTBLOCK>
struct cinema::FieldOutputBlockTemplate< CONSTBLOCK >

FieldOutput sub block class. FieldOutputBlock never own the memory of the sampling arrays, it is owned by the FieldOutput structure. Lifetime of a block is the same as its owner. Resizing, resetting the owner, or any other operation that will have the owner reallocate or deallocate memory will invalidate the blocks.

Member Function Documentation

GetSubBlock()

maxon::Result<FieldOutputBlockTemplate> GetSubBlock	(	Int	offset,
		Int	blockSize = FIELD_EXECUTION_BLOCK_SIZE
	)

Gets a sub-section of "this" which can be indexed from 0 to "blockSize".

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 FieldOutputBlock to default state (i.e. null count, no owner, no data, empty).

GetCount()

MAXON_ATTRIBUTE_FORCE_INLINE Int GetCount

(

)

const

Gets the number of elements in the sub block.

Returns

The count.

GetFullCount()

Int GetFullCount

(

)

const

Gets the number of elements used in the owning FieldOutput.

Returns

The count.

GetOffset()

MAXON_ATTRIBUTE_FORCE_INLINE Int GetOffset

(

)

const

Gets the offset of the sub block in the FieldOutput.

Returns

The offset.

GetOwner()

MAXON_ATTRIBUTE_FORCE_INLINE const FieldOutput* GetOwner

(

)

const

Returns the owner FieldOutput.

CopyFrom()

void CopyFrom

(

const FieldOutputBlockTemplate< CONSTBLOCK > &

src

)

Copies from the FieldOutputBlock described by src. Note that FieldOutputBlock never owns the arrays, so the copy only copies the raw pointers.

Parameters

[in]

src

Source for the duplication.

CopyArrayContentFrom()

maxon::Result<void> CopyArrayContentFrom

(

const typename std::conditional< CONSTBLOCK, maxon::DummyParamType, ConstFieldOutputBlock >::type &

src

)

Copies from the FieldOutput array content from src. Block size and flags will not be affected by this action. The destination allocated size must be big enough to accept the full content of the src block. Destination block will own memory if it is a normal block or not own it if it is a subblock.

Parameters

[in]

src

Source for the duplication.

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.

IsValid()

Bool IsValid

(

)

const

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

IsPopulated()

Bool IsPopulated

(

)

const

Checks if the FieldOutputBlock is valid and non-empty.

operator const typename std::conditional< CONSTBLOCK, maxon::DeleteReturnType01, ConstFieldOutputBlock >::type &()

operator const typename std::conditional< CONSTBLOCK, maxon::DeleteReturnType01, ConstFieldOutputBlock >::type &
