For example, if \c p 22120c8296dfb495f41d6f0de6fe1d03014ffd063674Douglas Gregor * is a pointer, code-completion might be triggered after the "-" and then 22130c8296dfb495f41d6f0de6fe1d03014ffd063674Douglas Gregor * after the ">" in \c p->.

For example, when code-completing for 22180c8296dfb495f41d6f0de6fe1d03014ffd063674Douglas Gregor * the expression \c p->get, the client should provide the location just after 22190c8296dfb495f41d6f0de6fe1d03014ffd063674Douglas Gregor * the ">" (e.g., pointing at the "g") to this code-completion hook.

The basic model 23211abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * for code completion is that Clang will parse a complete source file, 23221abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * performing syntax checking up to the location where code-completion has 23231abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * been requested. At that point, a special code-completion token is passed 23241abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * to the parser, which recognizes this token and determines, based on the 23251abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * current location in the C/Objective-C/C++ grammar and the state of 23261abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * semantic analysis, what completions to provide.

For example, if \c p 23321abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * is a pointer, code-completion might be triggered after the "-" and then 23331abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * after the ">" in \c p->. When the code-completion location is afer the ">", 23341abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * the completion results will provide, e.g., the members of the struct that 23351abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * "p" points to. The client is responsible for placing the cursor at the 23361abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * beginning of the token currently being typed, then filtering the results 23371abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * based on the contents of the token. For example, when code-completing for 23381abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * the expression \c p->get, the client should provide the location just after 23391abc6bca3d7fb0e7b1e40fbcad6cfb5e10594548Douglas Gregor * the ">" (e.g., pointing at the "g") to this code-completion hook.
