Method Detail

forEach

@Nonnull
public static QuantifierMatcher<Quantifier.ForEach> forEach(@Nonnull
                                                            ExpressionMatcher<? extends Bindable> rangesOverMatcher)

Matches a Quantifier.ForEach quantifier together with the given matcher for its rangesOver().

Parameters:

rangesOverMatcher - matcher for the rangesOver expression reference

Returns:

a matcher matching a for each quantifier together with the given matcher for reference it ranges over.

existential

@Nonnull
public static QuantifierMatcher<Quantifier.Existential> existential(@Nonnull
                                                                    ExpressionMatcher<? extends Bindable> rangesOverMatcher)

Matches a Quantifier.Existential quantifier together with the given matcher for its rangesOver().

Parameters:

rangesOverMatcher - matcher for the rangesOver expression reference

Returns:

a matcher matching an existential quantifier together with the given matcher for the reference it ranges over

physical

@Nonnull
public static QuantifierMatcher<Quantifier.Physical> physical(@Nonnull
                                                              ExpressionMatcher<? extends Bindable> rangesOverMatcher)

Matches a Quantifier.Physical quantifier together with the given matcher for its rangesOver().

Parameters:

rangesOverMatcher - matcher for the rangesOver expression reference

Returns:

a matcher matching a physical quantifier together with the given matcher for the reference it ranges over

ofKind

@Nonnull
public static <Q extends Quantifier> QuantifierMatcher<Q> ofKind(@Nonnull
                                                                 Class<? extends Q> quantifierClass,
