Constructors
| AstTaskEventHandlerNode(IFrameworkItem) | Initializes a new instance of the AstTaskEventHandlerNode class with the specified parent node. |
Fields
| ScopedNamePrefixBackingStore | |
| IsScopeImported |
Properties
| EventType | This value specifies the type of SSIS event that is handled by this event handler. It is selected from a list of event types recognized by the system. |
| EventTypeDefaultValue | Gets the default value for the EventType property |
| FriendlyTypeNameStatic | Gets the friendly name of the type of this node |
| Tasks | Container for child task definitions. |
| ConstraintMode | This value specifies the mode that should be used to execute the children of the container or package. Parallel directly matches the SSIS behavior and will require that precedence constraints are created manually for all task connections. Linear will automatically create precedence constraints so that tasks will run one after the other in the order that they are specified in the Biml. Linear is primarily useful for scripting scenarios where creating precedence constraints would be tedious. |
| SsisAnnotations | This is a collection of SSIS annotations that will be rendered on the SSIS design surface within the parent container object. |
| ConstraintModeDefaultValue | Gets the default value for the ConstraintMode property |
| VisibleVariables | Gets a collection of all variable nodes that are available to be used by this task. It includes variables defined by this task and any tasks/packages that contain this task |
| VisiblePackageParameters | Gets a collection of all package parameter nodes that are available to be used by this task. |
| VisibleProjectParameters | Gets a collection of all project parameter nodes that are available to be used by this task. This include all parameters defined by all package projects that contain the parent package for this task. |
| OutputPath | Gets a default OutputPath that all subsequent nodes will connect to, if they choose to create a precendence constraint |
| SystemVariables | Gets a collection of all variables defined in this task that have been provided by SSIS as system variables |
| PrecedenceConstraints | This is a container for task precedence constraint definitions. |
| Events | This is a collection of event handlers that can respond to SQL Server Integration Services events that are raised on this task. |
| DelayValidation | This value specifies whether the validation of the Dataflow task in SSIS should be delayed until the package is executed. DelayValidation is most often used when the ETL process references tables and other server assets that were created in an earlier stage of the data processing run. |
| IsolationLevel | Sets the Isolation Level which controls how Transactions behave for this container. |
| ForcedExecutionValue | If the ForceExecutionValue property is set to True, then the container will return the value stored in this property as its execution value. Otherwise, this value will be ignored. The default value for ForecedExecutionValue is 0. |
| ForceExecutionResult | This value indicates whether a specified execution result value will result if the container runs. The default value is None, which means that the container does not force a specified outcome. |
| ForceExecutionValue | Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain the value specified in the ForcedExecutionValue property. |
| ForcedExecutionValueDataType | This property specifies the data type of the value stored in the ForceExecutionValue property. |
| Disabled | This value specifies whether the item is disabled. The default value is False. |
| FailPackageOnFailure | This value determines whether the container will fail when a container component fails. If this container corresponds to a package, then the only valid value is False. |
| FailParentOnFailure | This value determines whether the parent container will fail when a child container failes. The default value is False. |
| MaximumErrorCount | This value specifies the maximum number of errors allowed to occur before a package is forced to stop running. The default value is 1. |
| Language | This specifies the default language to be used by this task and its descendants. |
| DisableEventHandlers | This value specifies whether the event handlers for this task, container, or package should be prevented from executing. The default value is False. |
| TransactionMode | This value specifies the transaction context in which this task will execute. |
| Variables | This is a container for variable definitions that are specific to this task, container, or package. |
| LoggingMode | This value specifies whether logging is enabled or disabled by the container or by the parent container. The default value is UseParentSetting. |
| LogEvents | This is a container for log event definitions that are specific to this task, container, or package. |
| LogProviders | Defines the log providers to use for the SSIS task or container |
| Expressions | This is a collection of SSIS expression definitions for property value overrides that are specific to this task, container, or package. |
| Id | Allows the developer to specify a unique identifier (GUID) for the package. This can be used to retain a consistent ID between builds. |
| DelayValidationDefaultValue | Gets the default value for the DelayValidation property |
| IsolationLevelDefaultValue | Gets the default value for the IsolationLevel property |
| ForcedExecutionValueDefaultValue | Gets the default value for the ForcedExecutionValue property |
| ForceExecutionResultDefaultValue | Gets the default value for the ForceExecutionResult property |
| ForceExecutionValueDefaultValue | Gets the default value for the ForceExecutionValue property |
| DisabledDefaultValue | Gets the default value for the Disabled property |
| FailPackageOnFailureDefaultValue | Gets the default value for the FailPackageOnFailure property |
| FailParentOnFailureDefaultValue | Gets the default value for the FailParentOnFailure property |
| MaximumErrorCountDefaultValue | Gets the default value for the MaximumErrorCount property |
| LanguageDefaultValue | Gets the default value for the Language property |

| TransactionModeDefaultValue | Gets the default value for the TransactionMode property |
| LoggingModeDefaultValue | Gets the default value for the LoggingMode 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 |
| SsisSafeScopedName | Returns a version of the ScopedName that has been cleaned of invalid characters for SSIS. |
| SsisSafeName | Returns a version of the Name that has been cleaned of invalid characters for SSIS. |
| 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. |
