Parameters

Parameter	Description
recordKey	A record key.
value	The property value.

Returns

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

Description

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);

Parameters

Parameter	Description
recordKey	A record key.
value	The property record.

Returns

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

Description

Loads a single property, still contained within a record.

// 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);

Declaration

public bool TryLoad(ulong documentKey, out IEnumerable<object> data);

Parameters

Parameter	Description
documentKey	A document key.
data	The document property values.

Returns

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

Description

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());

Declaration

public bool TryLoad(ulong documentKey, out IEnumerable<IPropertyDatabaseRecord> records);

Parameters

Parameter	Description
documentKey	A document key.
records	The document property records.

Returns

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

Description

Loads all the properties of a document, still contained within records.

// Load all values associated with a document, not deserialized.
var myAssetDocumentKey = PropertyDatabase.CreateDocumentKey("path/to/my/asset");
if (!propertyDatabase.TryLoad(myAssetDocumentKey, out IEnumerable<IPropertyDatabaseRecord> myDocumentRecords))
    Assert.Fail("Failed to load records for my asset document.");
var deserializedValues = new Dictionary<PropertyDatabaseRecordKey, object>();
foreach (var myDocumentRecord in myDocumentRecords)
{
    var value = propertyDatabase.GetValueFromRecord<object>(myDocumentRecord.value);
    deserializedValues.Add(myDocumentRecord.key, value);
}
Assert.AreEqual(5, deserializedValues.Count);
