Fields

Modifier and Type	Field	Description
(package private) static int	CHANGE_OPTIONAL
(package private) static int	CHANGE_SCOPE
(package private) java.util.List<ConflictResolver.ConflictItem>	children	The conflict items which are immediate children of the node, used to easily update those conflict items after a new parent scope/optionality was encountered.

(package private) java.lang.Object	derivedScopes	The set of derived scopes the node was visited with, used to check whether an already seen node needs to be revisited again in context of another scope.
(package private) int	minDepth	The smallest depth at which the node was seen, used for "the" depth of its conflict items.

Field Detail

minDepth

int minDepth

The smallest depth at which the node was seen, used for "the" depth of its conflict items.

derivedScopes

java.lang.Object derivedScopes

The set of derived scopes the node was visited with, used to check whether an already seen node needs to be revisited again in context of another scope. To conserve memory, we start with String and update to Set<String> if needed.

derivedOptionalities

int derivedOptionalities

The set of derived optionalities the node was visited with, used to check whether an already seen node needs to be revisited again in context of another optionality. To conserve memory, encoded as bit field (bit 0 -> optional=false, bit 1 -> optional=true).

children

java.util.List<ConflictResolver.ConflictItem> children

The conflict items which are immediate children of the node, used to easily update those conflict items after a new parent scope/optionality was encountered.
