Detailed Description

VSG extension Multiple-value field containing any number of SoInstanceParameter nodes.

This field contains a set of SoInstanceParameter instances , correctly maintaining their reference counts.

An SoMFInstanceParameter is written to file as one or more SoInstanceParameters. When more than one value is present, all of the values are enclosed in square brackets and separated by commas.

Convenience methods, for example setColors(), are provide to more easily set commonly used instance parameters.

Constructor & Destructor Documentation

SoMFInstanceParameter::SoMFInstanceParameter (  ) 

Default constructor.

virtual SoMFInstanceParameter::~SoMFInstanceParameter (  )  [virtual]

Destructor.


Member Function Documentation

virtual void SoMFInstanceParameter::disableDeleteValues (  )  [inline, virtual]

Temporary disable value deleting.

virtual void SoMFInstanceParameter::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 SoMFInstanceParameter::find ( SoInstanceParameter 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).

SoInstanceParameter* SoMFInstanceParameter::findParameterByName ( const SbString name  )  const

Returns the first parameter with the specified name.

Returns NULL if not found.

void SoMFInstanceParameter::finishEditing (  ) 

Indicates that batch edits have finished.

See also:
startEditing().
static SoType SoMFInstanceParameter::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoMField.

virtual SoType SoMFInstanceParameter::getTypeId (  )  const [virtual]

Returns the type identifier for this specific instance.

Implements SoTypedObject.

const SoInstanceParameter* * SoMFInstanceParameter::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 SoMFInstanceParameter::getValueSize (  )  const [inline, virtual]

Get size of the value.

Reimplemented from SoField.

virtual SbBool SoMFInstanceParameter::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 SoMFInstanceParameter::operator!= ( const SoMFInstanceParameter 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.

SoInstanceParameter* SoMFInstanceParameter::operator= ( SoInstanceParameter newValue  )  [inline]

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

the second and subsequent values.

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

Copy from another field of same type.

int SoMFInstanceParameter::operator== ( const SoMFInstanceParameter 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.

SoInstanceParameter* SoMFInstanceParameter::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.

bool SoMFInstanceParameter::removeParameterByName ( const SbString name  ) 

Remove the instance parameter with the specified name.

Returns true if successful, false if not found.

void SoMFInstanceParameter::set1Value ( int  index,
SoInstanceParameter newValue 
)

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

The array will be automatically expanded, if necessary.

SoInstanceParameter* SoMFInstanceParameter::setColors ( SbColor values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The color values as SbColor.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter* SoMFInstanceParameter::setRotations ( SbRotation values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The rotation values as SbRotation.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter* SoMFInstanceParameter::setRotations ( SbVec4f values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The rotation values as SbVec4f (quaternions).
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter* SoMFInstanceParameter::setScales ( SbVec3f values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The scale values as SbVec3f.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter* SoMFInstanceParameter::setTranslations ( SbVec3f values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The translation values as SbVec3f.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter* SoMFInstanceParameter::setTransparencies ( float *  values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The transparency values as float.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
void SoMFInstanceParameter::setValue ( SoInstanceParameter newValue  ) 

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

the second and subsequent values.

void SoMFInstanceParameter::setValues ( int  start,
int  num,
const SoInstanceParameter **  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 SoMFInstanceParameter::setValuesPointer ( int  num,
SoInstanceParameter **  userData 
)
void SoMFInstanceParameter::setValuesPointer ( int  num,
const SoInstanceParameter **  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).

SoInstanceParameter* SoMFInstanceParameter::setVisibilities ( int32_t *  values,
size_t  nbValues,
uint32_t  divisor = 1,
SoMemoryObject::CopyPolicy  policy = SoMemoryObject::NO_COPY 
)

Sets the value of this parameter from the input array.

Parameters:
values The visibility values as int32_t.
nbValues The number of values contained in the input array.
divisor The number of instances that share the same value.
policy Whether to copy the input values or not. NO_COPY_AND_DELETE and NO_COPY_AND_FREE are treated as NO_COPY.
SoInstanceParameter** SoMFInstanceParameter::startEditing (  ) 

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.
