The SoSFEnum class is a container for an enum value.
This field is used where nodes, engines or other field containers needs to store one particular value out of an enumerated set.
A field of this type stores its value to file as the symbolic name, rather than the actual integer value.
SoSFEnum instances are initialized on an instance basis, usually in the constructor of the fieldcontainer with the macros SO_NODE_DEFINE_ENUM_VALUE(enumtype, symbolvalue) and SO_NODE_SET_SF_ENUM_TYPE(enumfield, enumtype) for nodes, or for engines; SO_ENGINE_DEFINE_ENUM_VALUE() and SO_ENGINE_SET_SF_ENUM_TYPE().
Example initialization from the constructor of the SoCone class:
SO_NODE_DEFINE_ENUM_VALUE(Part, SIDES); SO_NODE_DEFINE_ENUM_VALUE(Part, BOTTOM); SO_NODE_DEFINE_ENUM_VALUE(Part, ALL); SO_NODE_SET_SF_ENUM_TYPE(parts, Part);
SoType SoSFEnum::getClassTypeId | ( | void | ) | [static] |
Returns a unique type identifier for this field class.
Reimplemented from SoSField.
Reimplemented in SoSFBitMask.
SoType SoSFEnum::getTypeId | ( | void | ) | const [virtual] |
Returns the type identification instance which uniquely identifies the Coin field class the object belongs to.
Implements SoField.
Reimplemented in SoSFBitMask.
void SoSFEnum::copyFrom | ( | const SoField & | f | ) | [virtual] |
Copy value(s) from f into this field. f must be of the same type as this field.
Implements SoField.
Reimplemented in SoSFBitMask.
SbBool SoSFEnum::isSame | ( | const SoField & | f | ) | const [virtual] |
void SoSFEnum::initClass | ( | void | ) | [static] |
Internal method called upon initialization of the library (from SoDB::init()) to set up the type system.
Reimplemented from SoSField.
Reimplemented in SoSFBitMask.
void SoSFEnum::setValue | ( | const SbName | name | ) |
Set the value of this field by specifying an enumeration string value.
void SoSFEnum::setEnums | ( | const int | num, |
const int * | vals, | ||
const SbName * | names | ||
) |
Makes a set of num enumeration names map to integer values, given by vals.
int SoSFEnum::getNumEnums | ( | void | ) | const |
Returns the number of enum names the SoSFEnum object understands.
Note that this API method is not part of the original SGI Inventor 2.1 API, and is an extension specific to Coin.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
int SoSFEnum::getEnum | ( | const int | idx, |
SbName & | name | ||
) | const |
Returns the value of the Nth enum this SoSFEnum object understands, and mutates name to contain the Nth enum's name.
Note that this API method is not part of the original SGI Inventor 2.1 API, and is an extension specific to Coin.
This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.
SbBool SoSFEnum::findEnumValue | ( | const SbName & | name, |
int & | val | ||
) | [protected, virtual] |
Return in val the enumeration value which matches the given enumeration name.
Returns TRUE
if name is a valid enumeration string, otherwise FALSE
.
SbBool SoSFEnum::findEnumName | ( | int | valuearg, |
const SbName *& | name | ||
) | const [protected, virtual] |
Set the enumeration name which matches the given enumeration value.
Returns TRUE
if value is a valid enumeration value, otherwise FALSE
.
int SoSFEnum::numEnums [protected] |
Number of enumeration mappings.
int * SoSFEnum::enumValues [protected] |
Array of enumeration values. Maps 1-to-1 with the enumNames.
SbName * SoSFEnum::enumNames [protected] |
Array of enumeration names. Maps 1-to-1 with the enumValues.
SbBool SoSFEnum::legalValuesSet [protected] |
Is TRUE
if a set of enum name-to-value mappings has been set.
