Member Function Documentation

virtual VOS_Object* VOS_RedlineObject::Divide ( int32  atOffset )

virtual

Splits the object in 2 and returns the bottom portion of the object.

Parameters

atOffset

is the split point, 0 < atOffset < VirtualLength().

Returns

the second half of the object.

Implements VOS_Object.

virtual VOS_Object* VOS_RedlineObject::Duplicate ( ) const

virtual

Create a copy of the object. It is not placed in the data structures, only copied.

Returns

a new copy.

Implements VOS_Object.

virtual bool16 VOS_RedlineObject::JoinWith ( VOS_Object *  next )

virtual

Called during Write(), allows two adjacent objects that have become identical to combine.

Parameters

next	is the object that occurs next in the data structure.

Returns

true when the 2 objects should be joined. If so the next object isn't written out.

Implements VOS_Object.

void VOS_RedlineObject::ReadWrite ( IPMStream *  s, ImplementationID  prop  )

virtual

The object needs to read or write itself to disk.

Parameters

s	is the IPMStream.
prop	is the implementationID of the object.

Implements VOS_Object.

virtual int32 VOS_RedlineObject::VirtualLength ( ) const

virtual

How many characters does this object represent?

Returns

the number of characters.

Implements VOS_Object.
