Code Inspection: Undefined class
Produces two types of warnings:
Undefined class: the declaration of referenced class is not found in the built-in library and project files.
Multiple declarations: multiple class definitions were found in project files. This can lead to issues with code completion, members resolution, and class inheritance analysis.
Use the options below to customize the inspection:
Don't report multiple class declaration potential problems: if selected, the inspection will not report classes having multiple definitions in project files.
Ignore: if selected, the inspection will not report the undefined classes referenced in PHPDoc blocks.
