Lucy::Analysis::CaseFolder – Normalize case, facilitating case-insensitive search.
CaseFolder is DEPRECATED. Use Normalizer instead.
CaseFolder normalizes text according to Unicode case-folding rules, so that searches will be case-insensitive.
lucy_CaseFolder* // incremented lucy_CaseFolder_new(void);
Constructor. Takes no arguments.
lucy_CaseFolder* lucy_CaseFolder_init( lucy_CaseFolder *self );
Initialize a CaseFolder.
lucy_Inversion* // incremented lucy_CaseFolder_Transform( lucy_CaseFolder *self, lucy_Inversion *inversion );
Take a single Inversion as input and returns an Inversion, either the same one (presumably transformed in some way), or a new one.
lucy_Inversion* // incremented lucy_CaseFolder_Transform_Text( lucy_CaseFolder *self, cfish_String *text );
Kick off an analysis chain, creating an Inversion from string input. The default implementation simply creates an initial Inversion with a single Token, then calls Transform(), but occasionally subclasses will provide an optimized implementation which minimizes string copies.
bool lucy_CaseFolder_Equals( lucy_CaseFolder *self, cfish_Obj *other );
Indicate whether two objects are the same. By default, compares the memory address.
cfish_Hash* // incremented lucy_CaseFolder_Dump( lucy_CaseFolder *self );
Dump the analyzer as hash.
Subclasses should call Dump() on the superclass. The returned object is a hash which should be populated with parameters of the analyzer.
Returns: A hash containing a description of the analyzer.
lucy_CaseFolder* // incremented lucy_CaseFolder_Load( lucy_CaseFolder *self, cfish_Obj *dump );
Reconstruct an analyzer from a dump.
Subclasses should first call Load() on the superclass. The
returned object is an analyzer which should be reconstructed by
setting the dumped parameters from the hash contained in
Note that the invocant analyzer is unused.
Returns: An analyzer.
Analyze text and return an array of token texts.
