Record Class ClassModifierChangeViability

java.lang.Record

org.ek9lang.compiler.common.ClassModifierChangeViability

Record Components:

possible - whether the change is structurally possible

reasonCode - a stable machine code for why not (null when possible). Predicate-specific codes such as "NO_OP", "TARGET_IS_ABSTRACT", "HAS_ABSTRACT_MEMBERS"

reason - a human-readable explanation (null when possible)

conflicts - structured list of blocking items (empty when possible or when not applicable)

public record ClassModifierChangeViability(boolean possible, String reasonCode, String reason, List<Map<String,Object>> conflicts)
extends Record

Outcome of asking whether a class's modifier (as open / as abstract) may be changed — the "declaration viability" layer used to gate the class-modifier toggle tooling and to decide whether the IDE should even offer the refactor.

Mirrors VisibilityChangeViability but adds a structured conflicts list for cases where the change is blocked by external dependencies (e.g. subtypes that would break if a class is made closed, or abstract methods that prevent making a class concrete).

Constructor Details

ClassModifierChangeViability

public ClassModifierChangeViability(boolean possible,
 String reasonCode,
 String reason,
 List<Map<String,Object>> conflicts)

Creates an instance of a ClassModifierChangeViability record class.

Parameters:

possible - the value for the possible record component

reasonCode - the value for the reasonCode record component

reason - the value for the reason record component

conflicts - the value for the conflicts record component

Method Details

viable

public static ClassModifierChangeViability viable()

notViable

public static ClassModifierChangeViability notViable(String reasonCode,
 String reason)

blocked

public static ClassModifierChangeViability blocked(String reasonCode,
 String reason,
 List<Map<String,Object>> conflicts)

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

possible

public boolean possible()

Returns the value of the possible record component.

Returns:

the value of the possible record component

reasonCode

public String reasonCode()

Returns the value of the reasonCode record component.

Returns:

the value of the reasonCode record component

reason

public String reason()

Returns the value of the reason record component.

Returns:

the value of the reason record component

conflicts

public List<Map<String,Object>> conflicts()

Returns the value of the conflicts record component.

Returns:

the value of the conflicts record component
