Uses of PostingIndex in org.terrier.structures

Classes in org.terrier.structures that implement PostingIndex

class	BitPostingIndex Class for various bit compressed index implementations, including parents to current DirectIndex and InvertedIndex implementations.
class	BlockDirectIndex Extended direct index that saves both block and field information about the terms that appear in a document.
class	BlockInvertedIndex This class implements the block field inverted index for performing retrieval.
class	DirectIndex A class that implements the direct index and saves information about whether a term appears in one of the specified fields.
class	InvertedIndex This class implements the inverted index for performing retrieval, with field information optionally.

Methods in org.terrier.structures that return PostingIndex
