Detailed Description

Multiple-value field containing any number of SbTime values.

A multiple-value field that contains any number of SbTime values.

SoMFTimes are written to file as one or more double-precision floating point values representing the length of time in seconds. Absolute times are measured relative to 00:00:00 GMT, January 1, 1970.

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

      [ 1.0, 1345600.1200055, 99.8 ]

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.



Constructor & Destructor Documentation

SoMFTime::SoMFTime (  ) 

Default constructor.

virtual SoMFTime::~SoMFTime (  )  [virtual]


Member Function Documentation

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

Temporary disable value deleting.

virtual void SoMFTime::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 SoMFTime::find ( const SbTime 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 SoMFTime::finishEditing (  )  [inline]

Indicates that batch edits have finished.

See startEditing().

static SoType SoMFTime::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoMField.

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

Returns the type identifier for this specific instance.

Implements SoTypedObject.

const SbTime* SoMFTime::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 SoMFTime::getValueSize (  )  const [inline, virtual]

Get size of the value.

Reimplemented from SoField.

virtual SbBool SoMFTime::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 SoMFTime::operator!= ( const SoMFTime 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 SbTime& SoMFTime::operator= ( const SbTime newValue  )  [inline]

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

the second and subsequent values.

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

Copy from another field of same type.

int SoMFTime::operator== ( const SoMFTime 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 SbTime& SoMFTime::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 SoMFTime::set1Value ( int  index,
const SbTime newValue 

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

The array will be automatically expanded, if necessary.

void SoMFTime::setValue ( const SbTime newValue  ) 

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

the second and subsequent values.

void SoMFTime::setValues ( int  start,
int  num,
const SbTime 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 SoMFTime::setValuesPointer ( int  num,
SbTime userData 
void SoMFTime::setValuesPointer ( int  num,
const SbTime 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).

SbTime* SoMFTime::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.
