Detailed Description

This class represents a set of properties that are going to be updated.

Usually this is simply a PROPPATCH request, but it can also be used for internal updates.

Property updates must always be atomic. This means that a property update must either completely succeed, or completely fail.

Member Function Documentation

◆ commit()

Sabre\DAV\PropPatch::commit ( )

Performs the actual update, and calls all callbacks.

This method returns true or false depending on if the operation was successful.

Returns: bool

If anywhere in this operation updating a property failed, we must update all other properties accordingly.

Here is the caller graph for this function:

◆ handle()

Sabre\DAV\PropPatch::handle	(		$properties,
		callable	$callback
	)

Call this function if you wish to handle updating certain properties.

For instance, your class may be responsible for handling updates for the {DAV:}displayname property.

In that case, call this method with the first argument "{DAV:}displayname" and a second argument that's a method that does the actual updating.

It's possible to specify more than one property as an array.

The callback must return a boolean or an it. If the result is true, the operation was considered successful. If it's false, it's consided failed.

If the result is an integer, we'll use that integer as the http status code associated with the operation.

Parameters

string \| string[]	$properties
callable	$callback

Returns: void
