Detailed Description

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

A multiple-value field that contains any number of two-dimensional vectors.

SoMFVec2ss are written to file as one or more pairs of short 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, 1 3, 100 17 ]
    

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.

SoMFVec2s::SoMFVec2s

(

)

Default constructor.

(

)

[virtual]

Destructor.

Member Function Documentation

virtual void SoMFVec2s::disableDeleteValues

(

)

[inline, virtual]

Temporary disable value deleting.

virtual void SoMFVec2s::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 SoMFVec2s::find	(	const SbVec2s &	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 SoMFVec2s::finishEditing

(

)

[inline]

Indicates that batch edits have finished.

See startEditing().

static SoType SoMFVec2s::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoMField.

virtual SoType SoMFVec2s::getTypeId

(

)

const [virtual]

Returns the type identifier for this specific instance.

Implements SoTypedObject.

const SbVec2s* SoMFVec2s::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 SoMFVec2s::getValueSize

(

)

const [inline, virtual]

Get size of the value.

Reimplemented from SoField.

virtual SbBool SoMFVec2s::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 SoMFVec2s::operator!=

(

const SoMFVec2s &

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 SbVec2s& SoMFVec2s::operator=

(

const SbVec2s &

newValue

)

[inline]

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

the second and subsequent values.

const SoMFVec2s& SoMFVec2s::operator=

(

const SoMFVec2s &

f

)

Copy from another field of same type.

int SoMFVec2s::operator==

(

const SoMFVec2s &

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 SbVec2s& SoMFVec2s::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 SoMFVec2s::set1Value	(	int	index,
		const SbVec2f &	vec2f
	)

Sets one value from single precision vector.

void SoMFVec2s::set1Value	(	int	index,
		const short	xy[2]
	)

Sets one value from 2 shorts in array.

void SoMFVec2s::set1Value	(	int	index,
		short	x,
		short	y
	)

Sets one value from 2 shorts.

void SoMFVec2s::set1Value	(	int	index,
		const SbVec2s &	newValue
	)

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

The array will be automatically expanded, if necessary.

void SoMFVec2s::setValue

(

const SbVec2f &

vec2f

)

Sets to one value from single precision vector.

void SoMFVec2s::setValue

(

const short

xy[2]

)

Sets to one value from 2 shorts in array.

void SoMFVec2s::setValue	(	short	x,
		short	y
	)

Sets to one value from 2 shorts.

void SoMFVec2s::setValue

(

const SbVec2s &

newValue

)

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

the second and subsequent values.

void SoMFVec2s::setValues	(	int	start,
		int	num,
		const SbVec2f *	vec2f
	)

Sets values from array of single precision vectors.

void SoMFVec2s::setValues	(	int	start,
		int	num,
		const short	xy[][2]
	)

Sets values from array of arrays of 2 shorts.

void SoMFVec2s::setValues	(	int	start,
		int	num,
		const SbVec2s *	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 SoMFVec2s::setValuesPointer	(	int	num,
		SbVec2s *	userData
	)

See setValuesPointer(int, const SbVec2s *).

void SoMFVec2s::setValuesPointer	(	int	num,
		const SbVec2s *	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 SoMFVec2s::setValuesPointer	(	int	num,
		short *	userData
	)

See setValuesPointer(int, const short *).

void SoMFVec2s::setValuesPointer	(	int	num,
		const short *	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).

SbVec2s* SoMFVec2s::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.
