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)`.

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).

getEffectiveChanges back to summary

getEffectiveChanges	back to summary
public static Map<String, ChangedValue> getEffectiveChanges(Map<String, Object> old, Map<String, Object> current) Returns a map that contains the new or changed mappings of `current` compared to `old`. A value has changed if `Objects#equals(Object, Object)` or `Arrays#equals(Object[], Object[])` returns `false` when invoked with the old and new value. Parameters old:Map<String, Object> the old mappings current:Map<String, Object> the current mappings Returns:Map<String, ChangedValue> a mapping of keys to changed values

public static Map<String, ChangedValue> getEffectiveChanges(Map<String, Object> old, Map<String, Object> current)

Returns a map that contains the new or changed mappings of current compared to old. A value has changed if Objects#equals(Object, Object) or Arrays#equals(Object[], Object[]) returns false when invoked with the old and new value.

Parameters

old:Map<String, Object>: the old mappings
current:Map<String, Object>: the current mappings

Returns:Map<String, ChangedValue>

a mapping of keys to changed values

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.

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.

newValue	back to summary
public Object newValue() Record Component getter of newValue. Record Component the new mappings

newValue

back to summary

public Object newValue()

Record Component getter of newValue.

Record Component: the new mappings

oldValue	back to summary
public Object oldValue() Record Component getter of oldValue. Record Component the old mappings

oldValue

back to summary

public Object oldValue()

Record Component getter of oldValue.

Record Component: the old mappings

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.

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.
