Record Class Classification

java.lang.Object

java.lang.Record

dev.braintrust.eval.Classification

Record Components:

name - optional grouping key; defaults to the owning classifier's resolved name when null or blank

id - stable identifier for the classification (required)

label - optional display label

metadata - optional arbitrary metadata

public record Classification(@Nullable String name, String id, @Nullable String label, @Nullable Map<String,Object> metadata)
extends Record

A single structured classification produced by a Classifier.

Unlike a Score (numeric 0-1), a Classification carries a stable id, an optional display label, and optional metadata. The name acts as the grouping key in the aggregated result map; when name is null or blank, the owning classifier's resolved name is used instead.

Classification

public Classification(@Nullable
 String name,
 String id,
 @Nullable
 String label,
 @Nullable
 Map<String,Object> metadata)

Creates an instance of a Classification record class.

Parameters:

name - the value for the name record component

id - the value for the id record component

label - the value for the label record component

metadata - the value for the metadata record component

Method Details

 String label)

of

public static Classification of(String name,
 String id,
 String label)

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.

name

@Nullable
public String name()

Returns the value of the name record component.

Returns:

the value of the name record component

id

public String id()

Returns the value of the id record component.

Returns:

the value of the id record component

label

@Nullable
public String label()

Returns the value of the label record component.

Returns:

the value of the label record component

metadata

@Nullable
public Map<String,Object> metadata()

Returns the value of the metadata record component.

Returns:

the value of the metadata record component
