Detailed Description
Multiple-value field containing any number of int32_t integers.
A multiple-value field that contains any number of int32_t (32-bit) integers.
SoMFInt32s are written to file as one or more integer values, in decimal, hexadecimal or octal format. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:
[ 17, -0xE20, -518820 ]
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.

| virtual SoMFInt32::~SoMFInt32 | ( | ) | [virtual] |
Destructor.
Member Function Documentation
| virtual void SoMFInt32::disableDeleteValues | ( | ) | [inline, virtual] |
Temporary disable value deleting.
| virtual void SoMFInt32::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 SoMFInt32::find | ( | int32_t | 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 SoMFInt32::finishEditing | ( | ) | [inline] |
Indicates that batch edits have finished.
See startEditing().
| static SoType SoMFInt32::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoMField.
| virtual SoType SoMFInt32::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Implements SoTypedObject.
| const int32_t* SoMFInt32::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 SoMFInt32::getValueSize | ( | ) | const [inline, virtual] |
Get size of the value.
Reimplemented from SoField.
| virtual SbBool SoMFInt32::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 SoMFInt32::operator!= | ( | const SoMFInt32 & | 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.
| int32_t SoMFInt32::operator= | ( | int32_t | newValue | ) | [inline] |
Sets the first value in the array to newValue, and deletes.
the second and subsequent values.
| int SoMFInt32::operator== | ( | const SoMFInt32 & | 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.
| int32_t SoMFInt32::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 SoMFInt32::set1Value | ( | int | index, | |
| int32_t | newValue | |||
| ) |
Sets the index'th value in the array to newValue.
The array will be automatically expanded, if necessary.
| void SoMFInt32::setValue | ( | int32_t | newValue | ) |
Sets the first value in the array to newValue, and deletes.
the second and subsequent values.
| void SoMFInt32::setValues | ( | int | start, | |
| int | num, | |||
| const int32_t * | 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 SoMFInt32::setValuesPointer | ( | int | num, | |
| int32_t * | userData | |||
| ) |
| void SoMFInt32::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).
| int32_t* SoMFInt32::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.
