Access Custom Metadata Type Records Using Static Methods
Use the Apex getAll(),
getInstance(recordId), getInstance(qualifiedApiName), and getInstance(developerName) methods to retrieve information from custom metadata type
records faster. These methods don’t rely on the SOQL engine and return the sObject details
directly from the call.
Where: This change applies to Enterprise, Performance, Unlimited, and Developer editions.
Why: The following example uses the getAll()
method. The custom metadata type named Games has a field
called GameType. This example determines if the field
value of the first record is equal to the string PC.
List<Games__mdt> mcs = Games__mdt.getall().values();
boolean textField = null;
if (mcs[0].GameType__c == 'PC') {
textField = true;
}
system.assertEquals(textField, true);
