Xml::TParserImpl Class Reference
The TParserImpl class hides the implementation of the CParser. It is responsible for building and maintaining the list of plugins in the parsing chain, and has ownership of several key objects within the framework.
Nested Classes and Structures
Constructor & Destructor Documentation
TParserImpl()
Default constructor
- Post-condition
- This object is properly constructed.
TParserImpl(const TParserImpl &)

AddPreloadedDictionaryL(const TDesC8 &)
| void | AddPreloadedDictionaryL | ( | const TDesC8 & | aPublicId | ) | |
BuildChainL(MContentHandler &, const RContentProcessorUids &)
This method builds the chain of plugins, so that information may flow down the chain.
The first in the chain is the parser, the last is the client.
Close()
This method cleans up the object before destruction. It releases all resources in accordance to the R Class pattern.
The framework will Close the StringDictionaryCollection and if owned will delete it.
- Post-condition
- This object may be allowed to go out of scope.
ConstructParserL(const CMatchData &, MContentHandler &)
This method constructs a MParser derived object.
-
leave
- KErrXmlParserPluginNotFound If ECom fails to find the object a leave occurs.
-
leave
- KErrArgument If CMatchData is lacking mandatory mime type field.
Parameters
| const CMatchData & aMatchData | Detailed criteria for parser resolution. |
| MContentHandler & aCallback | client to pass data to. |
ConstructPluginInReverseL(const TUid &, MContentHandler &)
This method constructs a CContentProcessor and places it in reverse order in the chain.
-
leave
- KErrXmlPluginNotFound If ECom fails to find the object a leave occurs.
Parameters
| const TUid & aImplementationUid | The implementation uid of the plugin. |
| MContentHandler & aCallback | client to pass data to. |
DestroyChain()
| void | DestroyChain | ( | ) | [private] |
Destroys the client and the chain of plugins not including the parser.
- Post-condition
- The chain and client are destroyed and parsing cannot take place.
DestroyContentProcessorPtrMapping(TAny *)
| void | DestroyContentProcessorPtrMapping | ( | TAny * | aPtr | ) | [private, static] |
Tidy memory associated with this object.
Parameters
| TAny * aPtr | The ContentProcessor pointer. |
IsFeatureEnabled(TInt)
|
TBool
| IsFeatureEnabled | ( | TInt | aParserFeature | ) | const |
OpenL(const CMatchData &, MContentHandler &)
This method opens and sets all the objects contents. The StringDictionaryCollection is created and Opened.
- Pre-condition
- The object has just been constructed and no other values have been set.
- Post-condition
- The objects members have been set to the values given.
Parameters
| const CMatchData & aMatchData | Detailed criteria for parser resolution. |
| MContentHandler & aCallback | client to pass data to. |
ParseChunkL(const TDesC8 &)
| void | ParseChunkL | ( | const TDesC8 & | aChunk | ) | |
This method starts the parser parsing a descriptor. The descriptor does not contain the last part of the document.
- Pre-condition
- OpenL has been called
Parameters
| const TDesC8 & aChunk | the chunk to parse - not the last chunk |
ParseFileL(RFs &, const TDesC &)
| void | ParseFileL | ( | RFs & | aFs, |
| | const TDesC & | aFilename |
| | ) | |
ParseLastChunkL(const TDesC8 &)
| void | ParseLastChunkL | ( | const TDesC8 & | aFinalChunk | ) | |
This method starts the parser parsing a descriptor. The descriptor contains the last part of the document.
- Pre-condition
- OpenL has been called
Parameters
| const TDesC8 & aFinalChunk | the final chunk to parse |
SetContentHandler(MContentHandler &)
Allows the user to set/change the client for this parse session.
- Pre-condition
- OpenL has been called
Parameters
| MContentHandler & aCallback | the client at the end of the callback chain that is to receive the parsed document information. |
SetMimeTypeL(const CMatchData &)
| void | SetMimeTypeL | ( | const CMatchData & | aCriteria | ) | |
Allows the user to set/change the parser mime type used for this parse session.
- Pre-condition
- OpenL has been called
Parameters
| const CMatchData & aCriteria | |
SetProcessorChainL(const RContentProcessorUids &)
Allows the user to change the client and set the plugin chain for this parse session.
- Pre-condition
- OpenL has been called
Parameters
| const RContentProcessorUids & aPlugins | a list of plugin implementation uids that make up the callback chain. |
