Generify dialog

Drop obsolete casts

If this option is checked, IntelliJ IDEA analyzes whether the parameter cast cases are changed by refactoring. If the resulting parameter type is similar to the obsolete one, the cast statement is removed.

Leave Object-parameterized types raw

Check this option to make objects, that have java.lang.Object as a parameter, raw.

Perform exhaustive search

Check this option to perform search in all nodes.

Generify Objects

Check this option to transform the java.lang.Object objects into the type they are actually used for.

Produce wildcard types

Check this option to produce wildcard types where possible (expressions like List<? extends String>).

Preserve raw arrays

If this checkbox is selected, the arrays are not changed to the arrays with parameterized types. Otherwise, the arrays will be transformed to parameterized type.

Clearing this checkbox can be risky and result in uncompilable code.
