// defaulter-gen is a tool for auto-generating Defaulter functions.
|
|
//
|
|
// Given a list of input directories, it will scan for top level types
|
|
// and generate efficient defaulters for an entire object from the sum
|
|
// of the SetDefault_* methods contained in the object tree.
|
|
//
|
|
// Generation is governed by comment tags in the source. Any package may
|
|
// request defaulter generation by including one or more comment tags at
|
|
// the package comment level:
|
|
//
|
|
// // +k8s:defaulter-gen=<field-name-to-flag>
|
|
//
|
|
// which will create defaulters for any type that contains the provided
|
|
// field name (if the type has defaulters). Any type may request explicit
|
|
// defaulting by providing the comment tag:
|
|
//
|
|
// // +k8s:defaulter-gen=true|false
|
|
//
|
|
// An existing defaulter method (`SetDefaults_TYPE`) can provide the
|
|
// comment tag:
|
|
//
|
|
// // +k8s:defaulter-gen=covers
|
|
//
|
|
// to indicate that the defaulter does not or should not call any nested
|
|
// defaulters.
