NAME
SoSFEnum -SYNOPSIS
#include <Inventor/fields/SoSFEnum.h>
Inherits SoSField.
Inherited by SoSFBitMask.
Detailed Description
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);

Member Function Documentation
SoType SoSFEnum::getClassTypeId (void) [static]
Returns a unique type identifier for this field class.
See also:
- getTypeId(), SoType
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.
See also:
- getClassTypeId(), SoType
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]
Check for equal type and value(s).
Implements SoField.
Reimplemented in SoSFBitMask.
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.
Referenced by SoField::initClasses().
void SoSFEnum::setValue (const SbName name)
Set the value of this field by specifying an enumeration string value.
References findEnumValue(), SbName::getString(), and SoDebugError::post().
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.
References enumNames, enumValues, legalValuesSet, and numEnums.
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.
Since:
- Coin 2.0
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.
References enumNames, enumValues, and numEnums.
Referenced by setValue().
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.
