Field Details

CONTRADICTION

static final ContradictionAcceptanceCondition CONTRADICTION

This constant is an alias for ContradictionAcceptanceCondition.INSTANCE, its only purpose is readability.

It is guaranteed that there is only one instance of the logical constant, therefore it is safe to perform == checks.

TAUTOLOGY

static final TautologyAcceptanceCondition TAUTOLOGY

This constant is an alias for TautologyAcceptanceCondition.INSTANCE, its only purpose is readability.

It is guaranteed that there is only one instance of the logical constant, therefore it is safe to perform == checks.

Method Details

arguments

default Stream<Argument> arguments()

Returns:

recursively computes all the arguments of this acceptance condition

getChildren

Set<AcceptanceCondition> getChildren()

Returns:

an unmodifiable set of children

accept

<U,
D> U accept(Visitor<U,D> visitor,
 D topDownData)

Passes the topDownData to the right visit method and returns the result of the visit method, performs no modifications on them.

This allows for type-safe traversal through the acceptance condition structure.

Type Parameters:

U - the bottom-up data

D - the top-down data

Parameters:

visitor - the visitor

topDownData - the data which is passed from the root of the acceptance condition to the leaf

Returns:

the result of the visit method

contains

default boolean contains(Argument arg)

Checks if the given argument is contained in this acceptance condition.

Note that this relation is reflexive, hence each argument contains itself.

Parameters:

arg - some argument

Returns:

true if the argument is contained

builder

static AcceptanceCondition.Builder builder(AcceptanceCondition acc)

Returns a left-associative builder.

Parameters:

acc - the base acceptance condition, e.g. an argument

Returns:

a builder
