static void fixParents ( fsmTree_t  tree, BOOL *  deletedChars  )

static

Remove symbols from the statistics of the ancestors of this node in case that is necessary.

Symbols are removed from the ancestors if they only have the same symbols as the child node (including the ones indicated in deletedChars).

Parameters

[in]	tree	node of the tree.
[in]	deletedChars	bit vector indicating which characters have been erased from the node statistics.
