Interface FoldingBlock<B extends FoldingBlock>

All Known Implementing Classes:

AbstractFoldingBlock, DefaultFoldingBlock

public interface FoldingBlock<B extends FoldingBlock>

Defines the requirements for an object that can be used to describe a collapsible source code block in the default code folding model. It is not a requirement for code folding blocks to implement this interface; rather, it is provided as an implementation convenience when using the default code folding model.

Since:

10.1.3
