callbackInfo()

Signature

callbackInfo() — returns struct

Available in: model Category: Miscellaneous Functions

Description

Returns a struct containing all callback definitions for this model, keyed by callback type (e.g., beforeSave, afterCreate). Each callback type contains an array of callback method names.

Examples

// 1. Inspect all registered callbacks for a model
info = model("Order").callbackInfo();
// info is a struct keyed by callback type, each containing an array of method names:
// {
//   beforeSave:               ["stampUpdatedAt"],
//   afterCreate:              ["sendConfirmationEmail"],
//   afterSave:                ["clearCacheEntries"],
//   beforeValidation:         [],
//   beforeValidationOnCreate: [],
//   afterValidation:          [],
//   afterFind:                [],
//   ...
// }

// 2. Check whether a specific callback type has any registered methods
info = model("User").callbackInfo();
if (arrayLen(info.beforeDelete)) {
    writeOutput("User model has beforeDelete callbacks.");
}

// 3. Loop over all callback types and their methods for debugging
info = model("Post").callbackInfo();
for (callbackType in info) {
    for (methodName in info[callbackType]) {
        writeOutput(callbackType & ": " & methodName);
    }
}
