Constructors
| AstVariableNode(IFrameworkItem) | Initializes a new instance of the AstVariableNode class with the specified parent node. |
Fields
| ScopedNamePrefixBackingStore | |
| IsScopeImported |
Properties
| EvaluateAsExpression | This value specifies whether the string value provided in the Value property and any subsequent value setting should be preprocessed before use. If true, the Value property will be treated as an expression using the SSIS expression syntax. |
| EvaluateAsExpressionDefaultValue | Gets the default value for the EvaluateAsExpression property |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| InheritFromPackageParentConfigurationString | This value specifies configuration information necessary to map the specified parent package variable value onto this variable value. |
| InheritFromPackageParentConfigurationStringDefaultValue | Gets the default value for the InheritFromPackageParentConfigurationString property |
| IsSystemVariable | Gets or sets whether this is a system variable, as opposed to a user defined variable. |
| Namespace | This value specifies the namespace to use for the variable definition. A common choice is 'User'. |
| NamespaceDefaultValue | Gets the default value for the Namespace property |
| QualifiedName | Gets the fully qualified SSIS name for this variable. |
| RaiseChangedEvent | This value specifies whether an event will be raised that will cause registered event handlers to execute when the value of this variable changes. |
| RaiseChangedEventDefaultValue | Gets the default value for the RaiseChangedEvent property |
| ReadOnly | This value specifies whether the initial variable value is read-only. |
| ReadOnlyDefaultValue | Gets the default value for the ReadOnly property |
| SsisSafeName | Returns a version of the Name that has been cleaned of invalid characters for SSIS. |
| SsisSafeScopedName | Returns a version of the ScopedName that has been cleaned of invalid characters for SSIS. |
| Value | This value specifies a default or initial value for the variable. The value string will be automatically converted to the data type specified in DataType if possible. If EvaluateAsExpression is set to true, then the SQL Server Integration Services (SSIS) expression for the parent variable shoud be specificed in this property. |
| DataType | This value specifies the type of the variable selected from the list of variable types supported by the system. |
| RawXmlValue | This value specifies a default or initial value for the variable. The value string will be automatically converted to the data type specified in TypeCode if possible. If EvaluateAsExpression is set to true, then the SQL Server Integration Services (SSIS) expression for the parent variable shoud be specificed in this property. |
| IncludeInDebugDump | This value specifies whether the value of this variable will be included in a debug dump. |
| Id | Allows the developer to specify a unique identifier (GUID) for the variable. This can be used to retain a consistent ID between builds. |
| RawXmlValueDefaultValue | Gets the default value for the RawXmlValue property |
| IncludeInDebugDumpDefaultValue | Gets the default value for the IncludeInDebugDump property |
| IdDefaultValue | Gets the default value for the Id property |
| ScopedName | Gets the scoped name which can be used to uniquely identify this object among other objects of its type |
| SymbolTable | Gets a reference to the symbol table that stores a reference to this and all other named objects in the project |
| Name | Specifies the name of the object. This name can be used to reference this object from anywhere else in the program. |
| References | Gets collection of FrameworkItemReference objects, which track rich information about the properties that hold references to this node. |
| NameDefaultValue | Gets the default value for the Name property |
| Guid | |
| Annotations | This is a collection of annotation items that can be used to specify documentation, tags, or other information. Annotations are particularly useful for storing information about nodes that can be used by BimlScript code. |
| ObjectTag | This property provides a general purpose storage mechanism for .NET objects to be associated with AstNode objects. It supplements the annotation system, which is intended for use with string-based metadata. |
| BimlFile | This value specifies the BimlFile in which the Biml code that defines AstNode resides. |
| ItemLabel | Gets a label that can be used to identify this node |
| ParentItem | This value specifies the parent of the current node. All nodes must have a valid parent in the Biml framework, except for the root node. |
