Here is a proposal to reduce all get...Block to 2

support matching any Block.
interface Block

CHILD,
/** Search recursively in children (and children of children etc...) **/
CHILDRECURSE,
/** Search in previous siblings **/
PREVIOUS,
/** Search recursively in previous siblings (and parent previous
sibling etc...) **/
PREVIOUSRECURSE,
/** Search in next siblings**/
NEXT,
/** Search recursively in next siblings (and children etc...)**/
NEXTRECURSE
}
[...]
List<Block> getBlocks(BlockMatcher matcher, TraversalStrategy
traversalStrategy, boolean recurse);
Block getFirstBlock(BlockMatcher matcher, TraversalStrategy
traversalStrategy, boolean recurse);
}
interface BlockMatcher
{
boolean match(Block block);
}
et on refactor tous les autres get*Block basé sur ceux la avec des
BlockMatcher prédéfinis (ClassBlockMatcher, MetaDataBlockMatcher,
etc...).
Note: the main use case for this change is to support MetaData search.
WDYT (especially on the vocabulary like "TraversalStrategy") ?
XPath calls these "axes", http://www.w3.org/TR/xpath/#axes .
We could stick to the same naming, since it's well known in the tree
document model world.
Otherwise I guess I agree with the change, although any generification
and abstractization of the current already abstract model scares me.
