Method Detail
-
<static> $k.define(id, dependencies, factory)Defines a module
- Parameters:
- {string} id Optional
- Optional module ID
- {string[]} dependencies
- IDs of required modules
- factory
- Factory that returns the value of the module
-
<static> $k.log(object, level, channel)Log an object on the current log stream (if available)
$k.log("New instance created");
$k.log("The cake is a lie", $k.LOG_WARNING, "Portal");
- Parameters:
- object
- Object to log. Will be converted with toString().
- level Optional
- Log level. Either a number or a string ("debug", "normal", "warning", "error").
- {string} channel
- Optional log channel.
-
<static> $k.mapInstances(internalName, proto)Map the prototype of instances of the type with the internal name to the prototype object
function Person() { } Person.prototype.fullName = function() { return this.attributeValue("familyName").toUpperCase() + ", " + this.attributeValue("firstName"); }; $k.mapInstances("person", Person); var persons = $k.Registry.type("person").instances(); for (var p in persons) $k.out.print(persons[p].fullName() + "\n");
- Parameters:
- {string} internalName
- Internal name of the type of instances to map
- proto
- Prototype object
-
<static> $k.mapModule(moduleName, registryID)Maps a module ID to the ID of a registered script. Allows to register scripts containing modules under a different ID
- Parameters:
- {string} moduleName
- The ID of the module
- {string} registryID
- The ID of the registered script
-
<static> $k.mapTypes(internalName, proto)Map the prototype of types with the internal name to the prototype object
- Parameters:
- {string} internalName
- Internal name of the type to map
- proto
- Prototype object
-
<static> $k.module(moduleName)Loads a module
- Parameters:
- {string} moduleName
- The ID of the module
- Throws:
- {$k.exception.ModuleError}
- If the module was not found or defined more than once
- Returns:
- The model value
-
<static> $k.optimisticTransaction(f)Evaluates the function in a transaction and returns its return value. Does not check if the transaction has been accepted or rejected. Allows to start a transaction within another transaction, the nested transaction will be a part of the outer transaction
- Parameters:
- {Function} f
- Function that should be evaluated in a transaction
- Throws:
- {$k.exception.TransactionError}
- If a read-only transaction is already active
- Returns:
- The return value of the function
- See:
- $k#.transaction
-
<static> $k.require(dependencies, callback)Calls a function with required modules. Passes the value of each required module
- Parameters:
- {string[]} dependencies
- IDs of required modules
- {function} callback
- Callback function
- Throws:
- {$k.exception.ModuleError}
- If a required module was not found, defined more than once, or a cyclic dependency was detected
- Returns:
- The return value of the callback function
-
Returns the root type of the semantic network
- Returns:
- {$k.Type}
-
Returns the parent type of all shortcut relation types
- Returns:
- {$k.Type}
-
<static> {boolean} $k.symmetricRelationProperties()Returns true if symmetric relation properties are enabled
- Returns:
- {boolean}
-
Returns the parent type of all system relation types
- Returns:
- {$k.Type}
-
Returns the parent type of all attribute types
- Returns:
- {$k.Type}
-
Returns the parent type of all relation types
- Returns:
- {$k.Type}
-
Returns all top types except the top attribute and relation types
- Returns:
- {$k.Type[]}
-
<static> $k.transaction(f, rejectFunction)Evaluates the function in a transaction and returns its return value if the transaction has been accepted. If the transaction is rejected due to concurrency conflicts, the optional reject function is performed. This function does not allow to start a transaction within an outer transaction, use optimisticTransaction() instead.
- Parameters:
- {Function} f
- Function that should be evaluated in a transaction
- {Function} rejectFunction Optional
- Optional function that is evaluated if the transaction is rejected.
- Throws:
- {$k.exception.TransactionError}
- If another transaction is already active
- Returns:
- The return value of the function. If the transaction is rejected, the return value of the reject function (if defined) or undefined is returned.
- See:
- $k#.optimisticTransaction
-
Returns the current user
- Returns:
- {$k.User}
-
Returns the parent type of user-defined relation type
- Returns:
- {$k.Type}
-
<static> {string} $k.uuid()Generates a UUID
- Returns:
- {string}
-
<static> {string} $k.volume()Returns the name of the semantic network
- Returns:
- {string}
