Class AstOfflineSchemaItemNode

The AstOfflineSchemaItemNode stores all information necessary to build a package that targets a specific table or query without having to inspect the schema information for the live table or query at build time. It is essentially a cache of column type information for a table or query result set.

Namespace:
Varigence.Languages.Biml.Metadata
Assembly:
Biml.dll

Constructors

AstOfflineSchemaItemNode(IFrameworkItem)

Initializes a new instance of the AstOfflineSchemaItemNode class with the specified parent node.

Fields

ScopedNamePrefixBackingStore
IsScopeImported

Properties

Columns

This is a collection of the columns stored in the offline metadata object.

Connection

Specifies the database connection at which this source of this schema item is defined. If not specified, the schema item will use the default database connection specified by the parent offline schema object.

FriendlyTypeNameStatic

Gets the friendly name of the type of this node

LogicalDisplayFolder

Specifies a path that should be used for organizing the tree display of this object in the Logical View in BimlStudio.

LogicalDisplayFolderDefaultValue

Gets the default value for the LogicalDisplayFolder property

ReferencedComponents

This is a collection of the dataflow components that were used as sources for the queries used to obtain this offline schema information. This information is persisted to enable changes to those components to be synchronized with the offline schema object.

Source

Specifies the source object that this offline metadata obect is caching the column information for.

UseForOfflineBuild

Specifies whether or not this offline schema object should be used to supply external column metadata for use in the building of SQL Server Integration Services (SSIS) data flow tasks.

UseForOfflineBuildDefaultValue

Gets the default value for the UseForOfflineBuild 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.

Methods

BindingScopeBoundaries()

Retrieves the permitted scope boundaries to bind references from this node.

DefinedAstNodes()

Retrieves a collection of nodes that have been defined as direct children of the current node.

Duplicate()

Creates a duplicate of the current node

Duplicate(IFrameworkItem)

Creates a duplicate of the current node with the specified parent item

GetAllItemsReferencedByDefinedSuccessors()

Builds a list of all items referenced by this node and its successors. Each tuple in the returned list represents a FrameworkItemReference. The first item is the ReferencingItem, the second item is the property name, and the third item is the ReferencedItem.

GetDefaultValue(String)

Retrieves the default value for the property with the name propertyName

GetDefaultValue<T>(String)

Retrieves the default value for the property with the name propertyName

GetDescriptiveBaseName()
GetDescriptiveLogicalDisplayFolder()
GetSchemaLocalName()

Retrieves the local XML element name that corresponds to this node in Biml code.

IsSynchronizedWithReferencedComponents()
StructureEquals(Object)

Compares this node to the provided object to determine if all defined children and references are equal.

SynchronizeWithReferencedComponents()
ToString()
