Functions

new

lucy_ORQuery* // incremented
lucy_ORQuery_new(
    cfish_Vector *children
);

Create a new ORQuery.

children

An array of child Queries.

init

lucy_ORQuery*
lucy_ORQuery_init(
    lucy_ORQuery *self,
    cfish_Vector *children
);

Initialize an ORQuery.

children

An array of child Queries.

Methods

Make_Compiler

lucy_Compiler* // incremented
lucy_ORQuery_Make_Compiler(
    lucy_ORQuery *self,
    lucy_Searcher *searcher,
    float boost,
    bool subordinate
);

Abstract factory method returning a Compiler derived from this Query.

searcher

A Searcher.

boost

A scoring multiplier.

subordinate

Indicates whether the Query is a subquery (as opposed to a top-level query). If false, the implementation must invoke Normalize() on the newly minted Compiler object before returning it.

To_String

cfish_String* // incremented
lucy_ORQuery_To_String(
    lucy_ORQuery *self
);

Generic stringification: “ClassName@hex_mem_address”.

Equals

bool
lucy_ORQuery_Equals(
    lucy_ORQuery *self,
    cfish_Obj *other
);

Indicate whether two objects are the same. By default, compares the memory address.

other

Another Obj.
