add back to summary

add	back to summary
public boolean add(ATNConfig config) Implements java.util.Set.add. Doc from java.util.Set.add. Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element `e` to this set if the set contains no element `e2` such that `Objects.equals(e, e2)`. If this set already contains the element, the call leaves the set unchanged and returns `false`. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements. The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular element, including `null`, and throw an exception, as described in the specification for `Collection.add`. Individual set implementations should clearly document any restrictions on the elements that they may contain. Parameters config:ATNConfig element to be added to this set Returns:boolean `true` if this set did not already contain the specified element Annotations @Override

public boolean add(ATNConfig config)

Implements java.util.Set.add.

Doc from java.util.Set.add.

Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element e to this set if the set contains no element e2 such that Objects.equals(e, e2). If this set already contains the element, the call leaves the set unchanged and returns false. In combination with the restriction on constructors, this ensures that sets never contain duplicate elements.

The stipulation above does not imply that sets must accept all elements; sets may refuse to add any particular element, including null, and throw an exception, as described in the specification for Collection.add.

add	back to summary
public boolean add(ATNConfig config, DoubleKeyMap<PredictionContext, PredictionContext, PredictionContext> mergeCache) Adding a new config means merging contexts with existing configs for `(s, i, pi, _)`, where `s` is the `ATNConfig#state`, `i` is the `ATNConfig#alt`, and `pi` is the `ATNConfig#semanticContext`. We use `(s,i,pi)` as key. This method updates `dipsIntoOuterContext` and `hasSemanticContext` when necessary.

public <T> T[] toArray(T[] a) Implements java.util.Set.toArray. Doc from java.util.Set.toArray. Returns an array containing all of the elements in this set; the runtime type of the returned array is that of the specified array. If the set fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this set. If this set fits in the specified array with room to spare (i.e., the array has more elements than this set), the element in the array immediately following the end of the set is set to `null`. (This is useful in determining the length of this set only if the caller knows that this set does not contain any null elements.) If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. Like the `toArray()` method, this method acts as bridge between array-based and collection-based APIs. Further, this method allows precise control over the runtime type of the output array, and may, under certain circumstances, be used to save allocation costs. Suppose `x` is a set known to contain only strings. The following code can be used to dump the set into a newly allocated array of `String`: String[] y = x.toArray(new String[0]); Note that `toArray(new Object[0])` is identical in function to `toArray()`.
