toString() Generation Settings dialog

Code | Generate - toString() - Settings

Settings tab

Item	Description
Use fully qualified class name in code generation ($classname)	If this checkbox is selected, the dumped classnames will include their package names. (The `$classname` variable in the Velocity templates)
Enable getters in code generation ($method)	If this checkbox is selected, the code generator will have `$methods` variable in the Velocity Macro Language. See example 2.
Move caret to the generated method	If this checkbox is selected, the caret scrolls to the generated `toString()` method.
Sort elements	If this checkbox is selected, the members are sorted in the selected order (ascending or descending).
When method already exists	In this section, choose the default conflict resolution policy: Ask: Choose this option to ask for confirmation, if a `toString()` method already exists. IntelliJ IDEA shows the dialog Replace existing toString method. The answer Yes results in generating the new `toString()` method in place of the existing one; the answer No results in creating a duplicate method. Replace existing: Choose this option to automatically replace the existing `toString()` code. Generate duplicating method: Choose this option to create a duplicate `toString()` method; in doing so, the new method will have the name `toString()`; the existing code will not be erased.
Where to insert?	In this section, choose the place to insert the generated `toString()` method. The possible options are: At caret. After equals() and hashCode(): the generated `toString()` method will be inserted after the equals/hashCode, if present in the Java class; otherwise, the new method will be inserted at the current caret position. At the end of class: the generated `toString()` method will be inserted as the last method.
Exclude	In this section, select the checkboxes next to the elements to be excluded from the `toString()` method generation: Exclude constant fields: If this checkbox is selected, then any constants won't be a part of the available fields for the code generator. Exclude static fields: If this checkbox is selected, then any fields that have static modifiers won't be part of available fields for the code generator. Exclude transient fields: If this checkbox is selected, then any fields with transient modifiers won't be be part of the available fields for the code generator. Exclude enum fields: If this checkbox is selected, then any fields of the type `enum` (JDK1.5) will not be part of available fields for the code generator. Exclude logger fields (Log4j, JDK Logging, Jakarta Common Logging): If this checkbox is selected, then any field that is a either a Log4j Logger, Java JDK Logger or a Jakarta Commons Logger will not be part of the available fields for the code generator. Exclude fields by name (reg exp): If this checkbox is selected, then IntelliJ IDEA performs a regular expression matching on the field name. If the result is true, then the field will not be part of the available fields for the code generator. Exclude fields by type name (reg exp): If this checkbox is selected, then IntelliJ IDEA performs a regular expression matching on the field type name (fully qualified name). If the result is true, the field will not be part of the available fields for the code generator. Exclude methods by name (reg exp): If this checkbox is selected, then IntelliJ IDEA performs a regular expression matching on the method name. If the result is true, the method will not be part of the available methods for the code generator. Exclude methods by return type name (reg exp): If this checkbox is selected, then IntelliJ IDEA performs a regular expression matching on the method return type name (fully qualified name). If the result is true, the method will not be part of the available methods for the code generator.
