PropertyDatabase.TryLoad

パラメーター

戻り値

bool True if the record is found and is valid, false otherwise.

説明

Loads a single property, already deseriazed into an object.

// Load the value already deserialized.
var colorRecordKey = PropertyDatabase.CreateRecordKey("path/to/my/asset", "m_Color");
if (!propertyDatabase.TryLoad(colorRecordKey, out object colorObject))
    Assert.Fail("Failed to load color property.");
var color = (Color)colorObject;
Assert.AreEqual(new Color(1, 0, 1), color);

パラメーター

戻り値

bool True if the record is found and is valid, false otherwise.

説明

Loads a single property, still contained within a record.

This method doesn't deserialize the value. You have to deserialize it yourself by calling PropertyDatabase.GetObjectFromRecordValue.

// Load the record value to do a deserialization at the appropriate time.
var sizeRecordKey = PropertyDatabase.CreateRecordKey("path/to/my/asset", "m_Size");
if (!propertyDatabase.TryLoad(sizeRecordKey, out IPropertyDatabaseRecordValue sizeRecordValue))
    Assert.Fail("Failed to load size property.");
var size = propertyDatabase.GetValueFromRecord<int>(sizeRecordValue);
Assert.AreEqual(42, size);

パラメーター

戻り値

bool True if the record is found and is valid, false otherwise.

説明

Loads all the properties of a document, already deseriazed into objects.

// Load all values not associated with a document, already deserialized.
var nullDocumentKey = PropertyDatabase.CreateDocumentKey(null);
if (!propertyDatabase.TryLoad(nullDocumentKey, out IEnumerable<object> noDocumentProperties))
    Assert.Fail("Failed to load properties with no documents.");
Assert.IsNotEmpty(noDocumentProperties);
Assert.AreEqual("myDocs_", noDocumentProperties.First());
