◆ add()

bool ossimImageChain::add ( ossimConnectableObject * source )

virtual

Will return true or false if an image source was added to the chain.

It will add and do a connection to the previous source automatically. This is a chain and the order of insertion matters. It adds it to the beginning of the list. The last one added is the first one to receive the getTile. Basically inserts to the right of the rightmost filter

For dynamic loading to take place we must allocate all objects first and then assign id's later.

We must remember the id's so we can do this. we will create a map that takes the id of the source as a key and a vector of input id's to connect it's inputs to.

◆ prepareForRemoval()

void ossimImageChain::prepareForRemoval ( ossimConnectableObject * connectableObject )

protected

Inserts all of this object's children and inputs into the container provided.

Since this is itself a form of container, this method will consolidate this chain with the argument container. Consequently, this chain object will not be represented in the container, but its children will be, with correct input and output connections to external objects. Ownership of children will pass to the argument container.

Returns: Returns TRUE if successful.
