## Constructor & Destructor Documentation

### SoLineDetail::SoLineDetail (void )

Default constructor sets up an empty, non-valid detail specification.

### SoLineDetail::~SoLineDetail () \[virtual\]

Destructor.

## Member Function Documentation

### SoType SoLineDetail::getTypeId (void ) const \[virtual\]

Returns the type identification of an object derived from a class inheriting **SoDetail**. This is used for runtime type checking and "downward" casting.

Implements **SoDetail**.

### SoType SoLineDetail::getClassTypeId (void ) \[static\]

This static method returns the **SoType** object associated with objects of this class.

### void SoLineDetail::cleanupClass (void ) \[inline\], \[static\]

This static method cleans up static data of the class.

### SoDetail \* SoLineDetail::copy (void ) const \[virtual\]

Return a deep copy of ourself.

**Note that if the Coin library has been built as a DLL under Microsoft Windows and you use this method from application code, you** *must* **make sure that both the Coin DLL and the application executable are using the same instance of a C Run-Time (CRT) library. Otherwise, you** *will* **get memory heap corruption upon deallocating the returned instances, eventually leading to mysterious crashes.**\

*Implements* **SoDetail***.*

### const SoPointDetail \* SoLineDetail::getPoint0 (void ) const

*Returns* **SoPointDetail** *describing the line start point.*

### const SoPointDetail \* SoLineDetail::getPoint1 (void ) const

*Returns* **SoPointDetail** *describing the line end point.*

### int SoLineDetail::getLineIndex (void ) const

*Returns the index of this line within the lineset node it is part of.*

### int SoLineDetail::getPartIndex (void ) const

*Returns the index of this line within the complex shape node it is part of.*

### void SoLineDetail::setPoint0 (const SoPointDetail \*const detail)

*Stores information about line's start point. Used internally from library client code setting up a* **SoLineDetail** *instance.*

**See also**

**getPoint0()**

### void SoLineDetail::setPoint1 (const SoPointDetail \*const detail)

*Stores information about line's end point. Used internally from library client code setting up a* **SoLineDetail** *instance.*

**See also**

**getPoint1()**

### void SoLineDetail::setLineIndex (const int idx)

*Used internally from library client code setting up a* **SoLineDetail** *instance.*

**See also**

**getLineIndex()**

### void SoLineDetail::setPartIndex (const int idx)

*Used internally from library client code setting up a* **SoLineDetail** *instance.*

**See also**

**getPartIndex()**

### void SoLineDetail::incLineIndex (void )

*Convenience method for library client code when setting up a* **SoLineDetail** *instance to use the line index as a counter.*

### void SoLineDetail::incPartIndex (void )

*Convenience method for library client code when setting up a* **SoLineDetail** *instance to use the part index as a counter.*
