⊟ Clear Method

Clears the contents of the data store.

⊟ Remarks

The data store is empty after a call to Clear.

⊟ Requirements

Namespace: SemWeb
Assembly: SemWeb (in SemWeb.dll)
Assembly Versions: 1.0.6.2

⊟ Import Method

Loads the contents of a StatementSource into the data store.

public void Import (StatementSource source)

⊟ Parameters

source

The source whose statements will be added into the data store.

⊟ Remarks

This method wraps a call to StatementSource.Select(StatementSink) in store-specific code that prepares the store for receiving many statements. The store may make itself locked for access by other processes to make the parsing faster. To avoid this, call StatementSource.Select(StatementSink) directly.

⊟ Requirements

Namespace: SemWeb
Assembly: SemWeb (in SemWeb.dll)
Assembly Versions: 1.0.6.2

⊟ Remove Method

Removes statements from the data store.

public void Remove (Statement template)

⊟ Parameters

template

A statement or statement template to remove from the data store.

⊟ Remarks

All statements in the data store that match template are removed. The template argument is a template. The non-null fields of template are used as a filter on the statements in the store. Statements that match the filter are removed. null fields of template are ignored during filtering. Any field in template (Subject, Predicate, Object, and Meta) may be null.

The following examples erase all statements in a store (although you should use ModifiableSource.Clear().

C# Example

store.Remove(new Statement(null, null, null)); store.Remove(Statement.All);

⊟ Requirements

Namespace: SemWeb
Assembly: SemWeb (in SemWeb.dll)
Assembly Versions: 1.0.6.2

⊟ RemoveAll Method

Removes all statements matching an array of templates.

public void RemoveAll (Statement[] templates)

⊟ Parameters

templates

An array of statement templates. Statement templates may contain a null subject, predicate, object, and/or meta.

⊟ Remarks

Stores may be more efficient removing statements in one call than through repeated calls to ModifiableSource.Remove(Statement).

Assembly: SemWeb (in SemWeb.dll)
Assembly Versions: 1.0.6.2
