%Compiler.Type.Literal

Class %Compiler.Type.Literal [ NoContext, System = 1 ]

Property class for literal values, for internal use only.

The property interface consists of several accessor methods. For literals, the following methods are defined: Get Set IsValid

For complex types, the following methods are defined in subclasses of this class. Refer to %Compiler.Type.Object for object types.

Parameters​

CAPTION;​

Parameter CAPTION;

A caption for the property usually used by client applications.

EXTERNALSQLNAME​

Parameter EXTERNALSQLNAME As STRING;

The name of the column in an external SQL table (gateway) to which this property is linked.

EXTERNALSQLTYPE​

Parameter EXTERNALSQLTYPE As STRING;

The original type of the column in an external SQL table (gateway) to which this property is linked.

CALCSELECTIVITY​

Parameter CALCSELECTIVITY As BOOLEAN = 1;

This parameter controls whether the SELECTIVITY of this property is calculated during TuneTable 1 means TuneTable will calculate the SELECTIVITY of the property/field. 0 means it will be skipped by TuneTable.

JAVATYPE;​

Parameter JAVATYPE;

The Java type to be used when exported.

STORAGEDEFAULT​

Parameter STORAGEDEFAULT As STRING [ Constraint = ",columnar,row,globalnode", Flags = ENUM ];

STORAGEDEFAULT is the type of storage used for the property if it is not already allocated in a DATA definition in the active STORAGE definition. Used to define a property as being stored as columnar in a hybrid row/column table. globalnode is used to store long data in its own global.

Methods​

Get​

Method Get() As %RawString [ CodeMode = generator, ServerOnly = 1 ]

SetT​

Method SetT() As %Status [ CodeMode = generator, Internal, ServerOnly = 1 ]

SetT() is the "triggered set" method generated solely for READONLY properties that are SQLCOMPUTED and are triggered by a non-null set of properties defined in SQLCOMPUTEONCHANGE. Not to be called by user code.

Set​

Method Set(newvalue As %RawString) As %Status [ CodeMode = generator, ServerOnly = 1 ]

Set the property to newvalue if is different from the current value.

IsValid​

ClassMethod IsValid(value As %RawString) As %Status [ CodeMode = generator, ServerOnly = 0 ]

Compute​

ClassMethod Compute(%id As %RawString) As %String [ CodeMode = generator, Internal, ProcedureBlock = 0, ServerOnly = 1 ]

This internal method is generated for properties with SQLCOMPUTED = true. It contains code to compute a value for the property as defined in SQLCOMPUTECODE. SQLCOMPUTECODE is scanned for {} references and those references are replaced by a formal argument. Do not attempt to call this method from user code.

SQLCompute​

ClassMethod SQLCompute() [ CodeMode = generator, Internal, ProcedureBlock = 0, ServerOnly = 1 ]

This internal method is generated for properties with SQLCOMPUTED = true. It contains code to compute a value for the property as defined in SQLCOMPUTECODE for the SQL Filer. Not to be called by user code.
