Record Class DeltaEntry

java.lang.Object

java.lang.Record

org.egothor.methodatlas.DeltaEntry

Record Components:

changeType - the type of change

before - the record from the before scan; null for DeltaEntry.ChangeType.ADDED entries

after - the record from the after scan; null for DeltaEntry.ChangeType.REMOVED entries

changedFields - names of fields that differ between before and after; empty for DeltaEntry.ChangeType.ADDED and DeltaEntry.ChangeType.REMOVED entries

public record DeltaEntry(DeltaEntry.ChangeType changeType, org.egothor.methodatlas.api.ScanRecord before, org.egothor.methodatlas.api.ScanRecord after, Set<String> changedFields)
extends Record

A single change entry in a MethodAtlas delta report.

Each entry describes one test method that was added, removed, or modified between two scan outputs. Entries are produced by DeltaReport.compute(java.nio.file.Path, java.nio.file.Path) and consumed by DeltaEmitter to produce human-readable output.

Change types

• DeltaEntry.ChangeType.ADDED — method is present in the after scan but absent from the before scan. before() is null.
• DeltaEntry.ChangeType.REMOVED — method is present in the before scan but absent from the after scan. after() is null.
• DeltaEntry.ChangeType.MODIFIED — method is present in both scans but one or more comparable fields differ. Both before() and after() are non-null. The changedFields() set names each field that differs.

Changed field names

The changedFields() set uses the following identifiers, which correspond to CSV column names or human-readable labels:

• "loc" — lines of code changed
• "tags" — JUnit @Tag set changed
• "source" — content_hash differs (class source was edited); only present when both records have a non-null contentHash
• "ai_security_relevant" — security-relevance classification flipped; only present when both records have a non-null aiSecurityRelevant
• "ai_tags" — AI taxonomy tag set changed; only present when both records have non-null aiTags

Constructor Details

DeltaEntry

public DeltaEntry(DeltaEntry.ChangeType changeType,
 org.egothor.methodatlas.api.ScanRecord before,
 org.egothor.methodatlas.api.ScanRecord after,
 Set<String> changedFields)

Creates an instance of a DeltaEntry record class.

Parameters:

changeType - the value for the changeType record component

before - the value for the before record component

after - the value for the after record component

changedFields - the value for the changedFields record component

Method Details

record

public org.egothor.methodatlas.api.ScanRecord record()

Returns the primary record for this entry.

For DeltaEntry.ChangeType.ADDED and DeltaEntry.ChangeType.MODIFIED entries this is the after() record. For DeltaEntry.ChangeType.REMOVED entries this is the before() record. Never returns null.

Returns:

the representative record for this entry

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. All components in this record class are compared with Objects::equals(Object,Object).

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.

changeType

public DeltaEntry.ChangeType changeType()

Returns the value of the changeType record component.

Returns:

the value of the changeType record component

before

public org.egothor.methodatlas.api.ScanRecord before()

Returns the value of the before record component.

Returns:

the value of the before record component

after

public org.egothor.methodatlas.api.ScanRecord after()

Returns the value of the after record component.

Returns:

the value of the after record component

changedFields

public Set<String> changedFields()

Returns the value of the changedFields record component.

Returns:

the value of the changedFields record component
