Detailed Description

Abstract Field containing an array of values.

Subclasses of this field can contain a 2D or 3D array of values of a specified type.

Member Enumeration Documentation

◆ CopyPolicy

enum SoSFArray::CopyPolicy

SoSFArray may be manipulating some large amounts of memory.

It is therefore convienent to be able to set the memory usage policy dynamically. By default, the memory policy is COPY, which is consistent with other OIV fields. The most likely to be efficient is NO_COPY. See also setNeverWrite.

Enumerator
COPY	Open Inventor will make a copy of the data (default)
NO_COPY	Passed buffer used , user will delete.
NO_COPY_AND_DELETE	Passed buffer used, SoSFImage will delete. Use this if memory is allocated with "new".
NO_COPY_AND_FREE	Passed buffer used, SoSFImage will free. Use this if memory is allocated with "malloc".

Definition at line 63 of file SoSFArray.h.

◆ DataType

enum SoSFArray::DataType

Supported data type enumeration values.

Enumerator
UNSIGNED_BYTE	UNSIGNED_BYTE.
UNSIGNED_SHORT	UNSIGNED_SHORT.
UNSIGNED_INT32	UNSIGNED_INT32.
SIGNED_BYTE	SIGNED_BYTE.
SIGNED_SHORT	SIGNED_SHORT.
SIGNED_INT32	SIGNED_INT32.
FLOAT	FLOAT.

Definition at line 85 of file SoSFArray.h.

Constructor & Destructor Documentation

◆ SoSFArray()

SoSFArray::SoSFArray ( )

Default constructor.

◆ ~SoSFArray()

virtual SoSFArray::~SoSFArray ( )

virtual

Destructor.

Member Function Documentation

◆ finishEditing()

void SoSFArray::finishEditing ( )

Indicates that batch edits have finished.

See startEditing().

◆ getClassTypeId()

static SoType SoSFArray::getClassTypeId ( )

static

Returns the type identifier for this class.

◆ getDataType()

DataType SoSFArray::getDataType ( ) const

inline

Returns the data type of the array.

Definition at line 113 of file SoSFArray.h.

◆ getSize()

const SbVec3i32 & SoSFArray::getSize ( ) const

inline

Returns the dimensions of the array.

Definition at line 263 of file SoSFArray.h.

◆ getTypeId()

virtual SoType SoSFArray::getTypeId ( ) const

virtual

Returns the type identifier for this specific instance.

Implements SoTypedObject.

Reimplemented in SoSFArray2D, and SoSFArray3D.

◆ getValue() [1/2]

void * SoSFArray::getValue ( ) const

inline

Returns a read-only pointer to the array's values.

Definition at line 253 of file SoSFArray.h.

◆ getValue() [2/2]

const void * SoSFArray::getValue	(	SbVec3i32 &	size,
		SbDataType &	dataType
	)		const

Returns a read-only pointer to the array's values and its dimensions and data type.

◆ getValueSize()

size_t SoSFArray::getValueSize ( ) const

inlinevirtual

Returns the size in bytes of one data value, e.g.

returns 1 if the data type is UNSIGNED_BYTE.

Reimplemented from SoField.

Definition at line 270 of file SoSFArray.h.

◆ isEmpty()

SbBool SoSFArray::isEmpty ( ) const

Returns TRUE if the current array is empty.

◆ isNeverWrite()

SbBool SoSFArray::isNeverWrite ( )

inline

Returns the "neverWrite" flag.

Definition at line 145 of file SoSFArray.h.

◆ operator!=()

virtual int SoSFArray::operator!= ( const SoSFArray & f ) const

inlinevirtual

Returns TRUE if all of the values of this field do not equal those of the given field f.

Definition at line 129 of file SoSFArray.h.

◆ operator=()

const SoSFArray & SoSFArray::operator= ( const SoSFArray & f )

Copy from another field of same type.

◆ operator==()

virtual int SoSFArray::operator== ( const SoSFArray & f ) const

virtual

Returns TRUE if all of the values of this field equal those of the given field f.

If the fields are different types FALSE will always be returned.

◆ setNeverWrite()

void SoSFArray::setNeverWrite ( SbBool neverWrite )

inline

Sets the "neverWrite" flag.

As this field may have to handle large amounts of data and its representation in an .iv file is not very efficient, it is often a good idea not to allow that data to be written out when required by a write action. By default, the "neverWrite" condition is FALSE.

Definition at line 139 of file SoSFArray.h.

◆ setValue() [1/2]

void SoSFArray::setValue	(	const SbVec3i32 &	size,
		const SbDataType &	dataType,
		const void *	data,
		CopyPolicy	copy = `COPY`
	)

Fill the array with data of the specified dimensions and type using the specified copy policy.

◆ setValue() [2/2]

void SoSFArray::setValue	(	const SbVec3i32 &	size,
		SoMemoryObject *	memObj,
		CopyPolicy	copy
	)

Fill the array with the specified dimensions and data from an SoMemoryObject using the specified copy policy.

◆ startEditing()

void * SoSFArray::startEditing	(	SbVec3i32 &	size,
		SbDataType &	dataType
	)

Returns a pointer to the internally maintained array that can be modified.

The values in the array may be changed, but values cannot be added or removed. It is illegal to call any other editing methods between startEditing() and finishEditing() (e.g. setValue(), etc.). Fields, engines or sensors connected to this field are not triggered until finishEditing() is called. Calling finishEditing() always sets the isDefault() flag to FALSE and informs engines and sensors that the field changed, even if none of the values actually were changed.
