Constructor Detail

JsonPropertySorter

public JsonPropertySorter(boolean sortAlphabeticallyIfNotAnnotated)

Constructor.

Parameters:

sortAlphabeticallyIfNotAnnotated - whether properties of a type without JsonPropertyOrder should be sorted alphabetically

Method Detail

compare

public int compare(MemberScope<?,?> first,
                   MemberScope<?,?> second)

Specified by:

compare in interface Comparator<MemberScope<?,?>>

getPropertyIndex

protected int getPropertyIndex(MemberScope<?,?> property)

Determine the given property's position in its declaring type's schema based on a JsonPropertyOrder annotation. If no such annotation is present, Integer.MAX_VALUE will be returned to append these at the end of the list of properties.

Parameters:

property - field/method for which the respective index should be determined

Returns:

specific property index or Integer.MAX_VALUE

shouldSortPropertiesAlphabetically

protected boolean shouldSortPropertiesAlphabetically(Class<?> declaringType)

Determine whether the given type's properties that are not specifically mentioned in a JsonPropertyOrder annotation should be sorted alphabetically, based on JsonPropertyOrder.alphabetic(). If no such annotation is present, the value given in the JsonPropertySorter(boolean) constructor.

Parameters:

declaringType - type for which the properties' default sorting should be determined

Returns:

whether properties that are not specifically mentioned in a JsonPropertyOrder annotation should be sorted alphabetically
