public Guess guessRequired(string $class, string $property)

Returns a guess whether a property of a class is required

Parameters

string $class The fully qualified class name
string $property The name of the property to guess for

public Guess guessMaxLength(string $class, string $property)

Returns a guess about the field's maximum length

public Guess guessPattern(string $class, string $property)

Returns a guess about the field's pattern

- When you have a min value, you guess a min length of this min (LOW_CONFIDENCE) , lines below
- If this value is a float type, this is wrong so you guess null with MEDIUM_CONFIDENCE to override the previous guess.
Example:
You want a float greater than 5, 4.512313 is not valid but length(4.512314) > length(5)

string $class The fully qualified class name
string $property The name of the property to guess for

Return Value

Guess A guess for the field's required pattern
