You can use %node% and %path% placeholders in your message to display, respectively, the node name and its complete path.

Parameters

string $message Deprecation message

Return Value

$this

$this treatNullLike(mixed $value)

Sets the equivalent value used when the node contains null.

Parameters

mixed $value

Return Value

$this

$this treatTrueLike(mixed $value)

Return Value

$this

ExprBuilder validate()

Sets an expression to run for the validation.

The expression receives the value of the node and must return it. It can modify it. An exception should be thrown when the node is not valid.
