Detailed Description

DOXYGEN-IGNORE FdoSchemaMergeContext provides support for updating a set of feature schemas base on a second set of schemas. It's main purpose is to support the reading of feature schemas from XML and the IApplySchema command implementations of certain providers (e.g. SDF Provider).

The schema updates can be done as an additive merge or based on the element states in the second set of schemas.

Warning:
This class is not yet part of the FDO API and is subject to change in the future. It's functions are exported for use by the SDF Provider.

virtual FDO_API bool FdoSchemaMergeContext::ClassHasObjects (  FdoClassDefinition *  classDef  )  [virtual]
 

Checks if a class has objects.

Warning:
This function is used as a pre-check to see if a class definition can be deleted. However, there is a chance that the class has no objects when this check is done, but an object is created by someone else before the class is deleted. Providers that need to prevent this race condition can do so by extending this function.
Parameters:
classDef Input the class to check
Returns:
Returns true if the class has objects ( the datastore for the current connection is checked for objects). Returns false if the class does not have objects or this context does not have a connection.

FDO_API void FdoSchemaMergeContext::CommitSchemas (   ) 
 

Merges the second set of schemas into the schemas to update. Resolves all references. If there are any errors these are thrown.

FDO_API FdoSchemaMergeContext* FdoSchemaMergeContext::Create (  FdoFeatureSchemaCollection *  schemas,
bool  defaultCapability = false
)  [static]
 

Constructs the Schema Merge Context.

Parameters:
schemas Input the features schemas to updated.
defaultCapability Input if true, then all types of schema element modifications are allowed by default. If false then none are allowed by default.
Returns:
Returns FdoSchemaMergeContext

FdoClassDefinition* FdoSchemaMergeContext::FindClass (  FdoFeatureSchemaCollection *  pSchemas,
FdoString *  schemaName,

) 
 

FDO_API FdoIConnection* FdoSchemaMergeContext::GetConnection (   ) 
 

Gets the FDO connection used by this context.

Returns:
Returns FdoIConnection. NULL if there is no current connection

virtual FDO_API bool FdoSchemaMergeContext::GetCopyElements (   )  [virtual]
 

Gets the current CopyElement setting.

Returns:
Returns true elements are always copied when the schemas are merged. Returns false if it is ok to simply move elements from the second set of schems to the schemas to update. CopyElements should only be false when the second set of schemas will be discarded when the schema merge is complete

FdoXmlFlags::ErrorLevel FdoSchemaMergeContext::GetErrorLevel (   ) 
 

Gets the current error level. Determines how strict the error checking is.

Returns:
Returns current error level.

FDO_API bool FdoSchemaMergeContext::GetIgnoreStates (   ) 
 

Gets the current IgnoreStates setting.

Returns:
Returns true if element states on second set of schemas are ignored. Second set of schemas is additively merged into schemas to update. Returns false if element states determine how schemas are merged

virtual FDO_API bool FdoSchemaMergeContext::GetReplaceClass (   )  [virtual]
 

Gets the current ReplaceClass setting.

Returns:
Returns true if properties, in the schemas to update, are deleted if not present in the second set of schemas. Returns false if class properties are additively merged (Properties in scheams to update are kept, even if not present in second set of schemas).

FDO_API FdoFeatureSchemaCollection* FdoSchemaMergeContext::GetSchemas (   )  const
 

Gets the schemas to update.

Returns:
Returns FdoFeatureSchemaCollection

FdoPtr<FdoFeatureSchemaCollection> FdoSchemaMergeContext::GetUpdSchemas (   )  const
 

Gets the second set of schemas.

Returns:
Returns FdoFeatureSchemaCollection

FDO_API void FdoSchemaMergeContext::SetConnection (  FdoIConnection *  connection  ) 
 

Sets the FDO connection used by this context. If a connection is provided then this context can do extra error checking based on the connection's provider capabilities and datastore contents.

Parameters:
connection Input the FDO connection.

virtual FDO_API void FdoSchemaMergeContext::SetCopyElements (  bool  copyElements  )  [virtual]
 

Sets the CopyElements setting.

Parameters:
copyElements Input the new CopyElements setting.

Sets the IgnoreStates setting.

Parameters:
ignoreStates Input the new IgnoreStates setting.

virtual FDO_API void FdoSchemaMergeContext::SetReplaceClass (  bool  replaceClass  )  [virtual]
 

Sets the ReplaceClass setting.

Parameters:
replaceClass Input the new ReplaceClass setting.

FDO_API void FdoSchemaMergeContext::SetUpdSchema (  FdoFeatureSchema *  schema  ) 
 

Sets the second set of schemas to be a single feature schema. This gets around a problem where a feature schema's element state is always changed to "Added" when it is added to a collection.

Parameters:
schemas Input the schema.

FDO_API void FdoSchemaMergeContext::SetUpdSchemas (  FdoFeatureSchemaCollection *  schemas  ) 
 

Sets the second set of schemas. This function must only be used when the current IgnoreStates setting is true.

Parameters:
schemas Input the schemas.
