serial class %Library.ArrayOfDataTypes extends %Collection.AbstractArrayOfDT, %SerialObject

The %ArrayOfDataTypes class represents an array of literal (i.e., data type) elements, each of which is associated with a unique key value. Keys can have any value, string or numeric.

Refer to %Collection.AbstractArray for a description of the varous array methods. These classes can be used 'stand alone' to store a collection.

Subclasses

Parameters

• parameter ELEMENTTYPE = "%String";
The type (class name) of the elements stored in the collection.

Properties

• property Data as %String [ MultiDimensional ];
Data is a private property used to hold the contents of the array.
• property ElementType as %String(MAXLEN=256) [ InitialExpression = ..#ELEMENTTYPE ];
The type (classname:propertyname) of the elements stored in the collection.

Methods

• method %ValidateObject(force As %Integer) as %Status
This method validates an object. The %Save method of a persistent class calls it before filing any objects in the database. The %ValidateObject method of a referencing object can call it. You can also call it explicitly at any time.

%ValidateObject does the following:

  1. It tests if any required property values are missing.
  2. If the PROPERTYVALIDATION class parameter is set to ValidateOnSave, it validates each non-null property value by calling the property method IsValid on each literal property and the object's %ValidateObject method for object-valued properties.
  3. If present, it will call a user-supplied %OnValidateObject method.

If any of these tests fail, %ValidateObject immediately returns an error value. It is up to the caller of %ValidateObject to process the error value.

Returns a %Status value indicating success or failure.

• classmethod BuildValueArray(serialized As %Binary, array As %Binary) as %Status
Constructs array(key)=value for each element in the serialval value.

Returns a %Status value indicating success or failure.

• method Clear() as %Status
Clears the contents of the array.

Returns a %Status value indicating success or failure.

• method Count() as %Integer
Returns the number of elements contained in the array.
• final method Define(key As %String) as %Boolean
This method is deprecated.

Please use IsDefined instead.

• method Find(element As %String, key As %String) as %String
Starting from, but not including, location key, finds the next element in the array with value equal to element.

If key is a null string (""), the search starts at the beginning of the array.

Find returns the key associated with the found element or null string ("") if no element is found.

• final method GetAt(key As %String = "") as %String
Finds and returns the value of the element associated with key.

GetAt returns the value of the element associated with key or null string ("") if no element is found.

• method GetNext(ByRef key As %String) as %String
Finds and returns the value of the element at the location after key in the array. If key is a null string (""), it returns the value of the first element in the array.

The value of key, which is passed by reference, is updated to the key value of the returned element or null string ("") if key is at the end of the array.

• method GetPrevious(ByRef key As %String) as %String
Finds and returns the value of the element at the location before key in the array. If key is a null string (""), it returns the value of the last element in the array.

The value of key, which is passed by reference, is updated to the key value of the returned element or null string ("") if key is at the beginning of the array.

• final method IsDefined(key As %String) as %Boolean
Returns true (1) if a value is defined at location key, otherwise false (0).
• classmethod LogicalToOdbc(val As %String = "") as %String
Converts the serial state of this array object to a delimited string using the value of the ODBCDELIMITER parameter as a delimiter.
• final method Next(key As %String = "") as %String
Finds and returns the key value of the element at the location following key in the array. If key is a null string (""), then Next returns the key value for the first element in the array.
• classmethod OdbcToLogical(val As %String = "") as %String
Converts the value of an incoming delimited string to a serialized state using the value of the ODBCDELIMITER parameter as a delimiter.
• final method Previous(key As %String = "") as %String
Finds and returns the key value of the element at the location preceding key in the array. If key is a null string (""), then Next returns the key value for the last element in the array.
• method RemoveAt(key As %String) as %String
Removes the element associated with key in the array.

RemoveAt returns the value of the removed element or null string ("") if no element was removed.

• method SetAt(element As %String, key As %String) as %Status
Sets the value of the element associated with key to element.

Returns a %Status value indicating success or failure.
