Interface AstProcessingChain<T>

Type Parameters:

T - The result type of this chain as obtained from the last processor

All Superinterfaces:

Iterable<AstProcessor>

All Known Implementing Classes:

LuceneProcessingChain

public interface AstProcessingChain<T>
extends Iterable<AstProcessor>

A chain of AstProcessors which are applied sequentially on an AST. Implementations must ensure that the chain is consistent, i.e. each processor understands the AST as created or modified by the previous processor.
