Record Class VisibilityChangeViability

java.lang.Object

java.lang.Record

org.ek9lang.compiler.common.VisibilityChangeViability

Record Components:

possible - whether the change is structurally possible

reasonCode - a stable machine code for why not (null when possible). EK9 error codes (e.g. "E07250") when the reason mirrors a compiler rule, otherwise a predicate-specific code (e.g. "NO_OP", "OVERRIDE_LOCKED")

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

public record VisibilityChangeViability(boolean possible, String reasonCode, String reason)
extends Record

Outcome of asking whether a member's visibility (access modifier) may be changed to a proposed value - the "declaration viability" layer used to gate the change_visibility tooling and to decide whether the IDE should even offer the refactor.

This answers ONLY whether the proposed modifier is structurally legal on the member (member kind, enclosing genus, override / open state). It does NOT consider whether narrowing the visibility would break existing call sites - that "narrowing safety" check is a separate, reference-graph concern performed by the tool at apply time.

Constructor Details

VisibilityChangeViability

public VisibilityChangeViability(boolean possible,
 String reasonCode,
 String reason)

Creates an instance of a VisibilityChangeViability 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

Method Details

viable

public static VisibilityChangeViability viable()

notViable

public static VisibilityChangeViability notViable(String reasonCode,
 String reason)

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
