Detailed Description

Multiple-value field containing any number of four-dimensional vectors.

A multiple-value field that contains any number of four-dimensional vectors, each vector component being an integer.

SoMFVec4i32s are written to file as one or more quadruples of integer values separated by whitespace.

When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:

     [ 0 0 0 1, 2 4 6 5, 8 -4 2 1 ]
    

Data copying:

SoMF fields are a kind of "smart container", automatically expanding as necessary to hold the data provided by the application. This is very convenient, but for large blocks of data it may be desireable to avoid making a copy of the application data. The setValuesPointer() methods allow Open Inventor to directly use an array of values supplied by the application. The application data is not copied. Please see SoMFVec3f for more information and example code.

Member Function Documentation

virtual void SoMFVec4i32::disableDeleteValues

(

)

[inline, virtual]

Temporary disable value deleting.

virtual void SoMFVec4i32::enableDeleteValues

(

)

[inline, virtual]

Sets the enableDeleteValues flag.

This flag (if TRUE) allows Open Inventor to destroy the user data array given to setValuesPointer(). This user data array will be managed exactly like internal field data values. Default is FALSE.

int SoMFVec4i32::find	(	const SbVec4i32 &	targetValue,
		SbBool	addIfNotFound = FALSE
	)

Finds the given targetValue in the array and returns the index of that value.

in the array. If the value is not found, -1 is returned. If addIfNotFound is set, then targetValue is added to the end of the array (but -1 is still returned).

void SoMFVec4i32::finishEditing

(

)

[inline]

Indicates that batch edits have finished.

See startEditing().

static SoType SoMFVec4i32::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoMField.

virtual SoType SoMFVec4i32::getTypeId

(

)

const [virtual]

Returns the type identifier for this specific instance.

Implements SoTypedObject.

const SbVec4i32* SoMFVec4i32::getValues

(

int

start

)

const [inline]

Returns a pointer into the array of values in the field, starting at index start.

The values are read-only. See the startEditing()/finishEditing() methods for a way of modifying values in place.

virtual size_t SoMFVec4i32::getValueSize

(

)

const [inline, virtual]

Get size of the value.

Reimplemented from SoField.

virtual SbBool SoMFVec4i32::isDeleteValuesEnabled

(

)

[inline, virtual]

Returns FALSE if user data array has been given to.

setValuesPointer() and enableDeleteValues() has never been called, and memory for data has not been reallocated. Otherwise, returns TRUE.

int SoMFVec4i32::operator!=

(

const SoMFVec4i32 &

f

)

const [inline]

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

those of the given f. If the fields are different types TRUE will always be returned.

Reimplemented from SoField.

const SbVec4i32& SoMFVec4i32::operator=

(

const SbVec4i32 &

newValue

)

[inline]

Sets the first value in the array to newValue, and deletes.

the second and subsequent values.

const SoMFVec4i32& SoMFVec4i32::operator=

(

const SoMFVec4i32 &

f

)

Copy from another field of same type.

int SoMFVec4i32::operator==

(

const SoMFVec4i32 &

f

)

const

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

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

Reimplemented from SoField.

const SbVec4i32& SoMFVec4i32::operator[]

(

int

i

)

const [inline]

Returns the i'th value of the field.

Indexing past the end of the field (passing in i greater than getNum()) will return garbage.

void SoMFVec4i32::set1Value	(	int	index,
		const SbVec4d &	vec4d
	)

Sets one value from double precision vector.

void SoMFVec4i32::set1Value	(	int	index,
		const SbVec4f &	vec4f
	)

Sets one value from single precision vector.

void SoMFVec4i32::set1Value	(	int	index,
		const int32_t	xyzw[4]
	)

Sets one value from 4 integers in array.

void SoMFVec4i32::set1Value	(	int	index,
		int32_t	x,
		int32_t	y,
		int32_t	z,
		int32_t	w
	)

Sets one value from 4 integers.

void SoMFVec4i32::set1Value	(	int	index,
		const SbVec4i32 &	newValue
	)

Sets the index'th value in the array to newValue.

The array will be automatically expanded, if necessary.

void SoMFVec4i32::setValue

(

const SbVec4d &

vec4d

)

Sets to one value from double precision vector.

void SoMFVec4i32::setValue

(

const SbVec4f &

vec4f

)

Sets to one value from single precision vector.

void SoMFVec4i32::setValue

(

const int32_t

xyzw[4]

)

Sets to one value from 4 integers in array.

void SoMFVec4i32::setValue	(	int32_t	x,
		int32_t	y,
		int32_t	z,
		int32_t	w
	)

Sets to one value from 4 integers.

void SoMFVec4i32::setValue

(

const SbVec4i32 &

newValue

)

Sets the first value in the array to newValue, and deletes.

the second and subsequent values.

void SoMFVec4i32::setValues	(	int	start,
		int	num,
		const SbVec4d *	vec4d
	)

Sets values from array of double precision vectors.

void SoMFVec4i32::setValues	(	int	start,
		int	num,
		const SbVec4f *	vec4f
	)

Sets values from array of single precision vectors.

void SoMFVec4i32::setValues	(	int	start,
		int	num,
		const int32_t	xyzw[][4]
	)

Sets values from array of arrays of 4 integers.

void SoMFVec4i32::setValues	(	int	start,
		int	num,
		const SbVec4i32 *	newValues
	)

Sets num values starting at index start to the values.

in newValues. The array will automatically be made larger to accommodate the new values, if necessary.

void SoMFVec4i32::setValuesPointer	(	int	num,
		SbVec4i32 *	userData
	)

See setValuesPointer(int, const SbVec4i32 *).

void SoMFVec4i32::setValuesPointer	(	int	num,
		const SbVec4i32 *	userData
	)

Sets the field to contain the num values stored in userData array.

This array will not be copied into the field: it will be directly used by the field. If num and userData are not correctly specified, the results are undefined (and probably undesirable). param num is the number of values that userData contains and must be a positive integer. param userData is an array allocated by malloc or realloc and can be deallocated by free (no constructor or destructor is called). userData must not be NULL. Its size must be at least num*sizeof(valueType).

void SoMFVec4i32::setValuesPointer	(	int	num,
		int32_t *	userData
	)

See setValuesPointer(int, const int32_t *).

void SoMFVec4i32::setValuesPointer	(	int	num,
		const int32_t *	userData
	)

Sets the field to contain the num values stored in userData array.

This array will not be copied into the field: it will be directly used by the field. If num and userData are not correctly specified, the results are undefined (and probably undesirable). param num is the number of values that userData contains and must be a positive integer. param userData is an array allocated by malloc or realloc and can be deallocated by free (no constructor or destructor is called). userData must not be NULL. Its size must be at least num*sizeof(valueType).

SbVec4i32* SoMFVec4i32::startEditing

(

)

[inline]

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. set1Value(), setValue(), etc.). Fields, engines or sensors connected to this field and sensors are not notified that this field has changed 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.
