/**
|
|
* Encapsulates a collection of components following the {@link GridFieldComponent} interface.
|
|
* While the {@link GridField} itself has some configuration in the form of setters,
|
|
* most of the details are dealt with through components.
|
|
*
|
|
* For example, you would add a {@link GridFieldPaginator} component to enable
|
|
* pagination on the listed records, and configure it through {@link GridFieldPaginator->setItemsPerPage()}.
|
|
*
|
|
* In order to reduce the amount of custom code required, the framework provides
|
|
* some default configurations for common use cases:
|
|
* - {@link GridFieldConfig_Base} (added by default to GridField)
|
|
* - {@link GridFieldConfig_RecordEditor}
|
|
* - {@link GridFieldConfig_RelationEditor}
