Notes

In Apex, the putAll(fromMap) method is used to add all key-value pairs from one map (fromMap) to another map. This method is part of the Map class in Salesforce Apex.

Here's a brief explanation:

Map<String, Object> destinationMap = new Map<String, Object>{
    'Key1' => 'Value1',
    'Key2' => 'Value2'
};

Map<String, Object> sourceMap = new Map<String, Object>{
    'Key3' => 'Value3',
    'Key4' => 'Value4'
};

destinationMap.putAll(sourceMap);

System.debug(destinationMap);

Output: {Key1=Value1, Key2=Value2, Key3=Value3, Key4=Value4}
