public record ClassIndex(int version, String timestamp, String classpathHash, List<ClassIndexEntry> entries)
extends Record

Class Index - Immutable record representing a pre-built class index 类索引 - 表示预构建类索引的不可变记录

Contains a versioned, timestamped snapshot of all scanned class metadata along with a classpath hash for staleness detection.

包含所有已扫描类元数据的带版本号和时间戳的快照， 以及用于陈旧检测的 classpath 哈希值。

ClassIndex

public ClassIndex(int version,
 String timestamp,
 String classpathHash,
 List<ClassIndexEntry> entries)

Create a class index with defensive copy of entries 创建类索引，对条目列表进行防御性拷贝

Parameters:

version - index format version | 索引格式版本

timestamp - creation timestamp in ISO-8601 format | ISO-8601 格式的创建时间戳

classpathHash - SHA-256 hash of the classpath for staleness detection | 用于陈旧检测的 classpath SHA-256 哈希值

entries - list of class index entries | 类索引条目列表

Method Details

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.

version

public int version()

Returns the value of the version record component.

Returns:

the value of the version record component

timestamp

public String timestamp()

Returns the value of the timestamp record component.

Returns:

the value of the timestamp record component

classpathHash

public String classpathHash()

Returns the value of the classpathHash record component.

Returns:

the value of the classpathHash record component

entries

public List<ClassIndexEntry> entries()

Returns the value of the entries record component.

Returns:

the value of the entries record component
