Interface TransitionSet

All Superinterfaces:

JsonConvertible

All Known Implementing Classes:

ASTTransitionSet, NFATransitionSet, PrioritySensitiveNFATransitionSet

public interface TransitionSet
extends JsonConvertible

Represents a set of NFA transitions to be used in TransitionBuilder. The set of NFA transitions implicitly also represents a set of NFA target states, which should be used to determine equality between instances of this class.

Method Summary

Modifier and Type	Method and Description
void	addAll(TransitionSet other) Add the contents of other to this, analogous to Set.addAll(Collection).
TransitionSet	createMerged(TransitionSet other) Create a merged set of this and other by copying this and adding the contents of other to the copy.
boolean	equals(Object obj) Checks if this transition set is equal to another.
int	hashCode() Returns the hash code value for this object.

Method Detail

createMerged

TransitionSet createMerged(TransitionSet other)

Create a merged set of this and other by copying this and adding the contents of other to the copy.

Parameters:

other - the TransitionSet to be merged with the copy. Implementing classes may accept objects of their own type only.

Returns:

the merged set. MUST be of the same type as this!

addAll

void addAll(TransitionSet other)

Add the contents of other to this, analogous to Set.addAll(Collection).

Parameters:

other - the TransitionSet to be merged with this. Implementing classes may accept objects of their own type only.

hashCode

int hashCode()

Returns the hash code value for this object. The hash should be calculated from the set of target states represented by this transition set!

Overrides:

hashCode in class Object

equals

boolean equals(Object obj)

Checks if this transition set is equal to another. Two transition sets should be treated as equal if and only if their set of target states is equal!

Overrides:

equals in class Object
