equals back to summary

equals	back to summary
public final boolean equals(Object o) Implements abstract java.lang.Record.equals. Doc from java.lang.Record.equals. Indicates whether some other object is "equal to" this one. In addition to the general contract of `Object.equals`, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: R copy = new R(r.c1(), r.c2(), ..., r.cn()); then it must be the case that `r.equals(copy)`. Parameters o:Object the reference object with which to compare. Returns:boolean `true` if this record is equal to the argument; `false` otherwise.

public final boolean equals(Object o)

Implements abstract java.lang.Record.equals.

Doc from java.lang.Record.equals.

Indicates whether some other object is "equal to" this one. In addition to the general contract of Object.equals, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows:

    R copy = new R(r.c1(), r.c2(), ..., r.cn());

then it must be the case that r.equals(copy).

Parameters

o:Object: the reference object with which to compare.

Returns:boolean

true if this record is equal to the argument; false otherwise.

hashCode back to summary

hashCode	back to summary
public final int hashCode() Implements abstract java.lang.Record.hashCode. Doc from java.lang.Record.hashCode. Returns a hash code value for the record. Obeys the general contract of `Object.hashCode`. For records, hashing behavior is constrained by the refined contract of `Record.equals`, so that any two records created from the same components must have the same hash code. Returns:int a hash code value for this record.

public final int hashCode()

Implements abstract java.lang.Record.hashCode.

Doc from java.lang.Record.hashCode.

Returns a hash code value for the record. Obeys the general contract of Object.hashCode. For records, hashing behavior is constrained by the refined contract of Record.equals, so that any two records created from the same components must have the same hash code.

toString back to summary

toString	back to summary
public final String toString() Implements abstract java.lang.Record.toString. Doc from java.lang.Record.toString. Returns a string representation of the record. In accordance with the general contract of `Object#toString()`, the `toString` method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read. In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves. Returns:String a string representation of the object.

public final String toString()
