Class DdsModelLpexAdapter

java.lang.Object
  com.ibm.etools.iseries.edit.language.model.DdsModelLpexAdapter

All Implemented Interfaces:

IDdsLanguageModel, ISystemTextEditorAdapterContributor

public class DdsModelLpexAdapter
extends Object
implements IDdsLanguageModel, ISystemTextEditorAdapterContributor

This class manages a DdsModel for a particular LpexTextEditor. It keeps the contents of the editor and model in synch and manages the broadcasting of selection events.

Nested Class Summary

class	DdsModelLpexAdapter.LpexFileReader
class	DdsModelLpexAdapter.LpexSourceFile This class enables the DDS parser to parse the contents of an Lpex editor
class	DdsModelLpexAdapter.ParseDdsModelJob Asynchronously reparse the DDS file and refresh the outline view This job belongs to the family of jobs that parse the DDS model for this editor.
class	DdsModelLpexAdapter.ParseJobScheduler This class schedules jobs to parse the model from the editor's contents in the background.

Constructor Detail

DdsModelLpexAdapter

public DdsModelLpexAdapter(LpexTextEditor editor,
                           int iCCSID,
                           IBMiConnection connection)

Constructor used from an ISeriesEditorParser that already has computed the necessary parameters

DdsModelLpexAdapter

public DdsModelLpexAdapter(LpexTextEditor editor)

Constructor if you do not have the connection and CCSID already computed.

Method Detail

getAdapter

public Object getAdapter(LpexTextEditor editor,
                         Class classRequired)

Adapter factory for creating DDS language model objects

Specified by:

getAdapter in interface ISystemTextEditorAdapterContributor

See Also:

com.ibm.etools.systems.editor.ISystemTextEditorAdapterContributor#getAdapter(com.ibm.lpex.alef.LpexTextEditor, java.lang.Class)

getDdsCursorListener

public IDdsParserAdapter getDdsCursorListener()

Return the singleton cursor listener that implements IDdsAdaptable. Lazily create the singleton.

addDdsSelectionListener

public void addDdsSelectionListener(IDdsParserListener listener)

Add listener which will be notified whenever the cursor moves to a different DDS element in the source

Specified by:

addDdsSelectionListener in interface IDdsLanguageModel

Parameters:

listener - IDdsParserListener

initializeDdsModel

protected void initializeDdsModel()

When this object is created - a DdsModel is not immediately created until it is requested by someone. This is the method by which it is requested.

setEditor

public void setEditor(LpexTextEditor editor)

Set the view for the first time May need to set up listeners Computes the DDS type

Parameters:

initialView - The Lpex view to set.

setIFile

public void setIFile(IFile file)

Parameters:

file - The iFile to set.

handleFileRename

public void handleFileRename()

From the editor find the file that is currently being edited Set the current DDS type based on its extension

getDdsModel

public DdsModel getDdsModel()

Retrieve DDS model corresponding to the source in the editor. Returns null if no model has been parsed

Specified by:

getDdsModel in interface IDdsLanguageModel

Returns:

getDdsModelSynchronously

public DdsModel getDdsModelSynchronously()

Retrieve DDS model corresponding to the source in the editor. Parse and create model if it does not exist. Will only return null if the user has cancelled the operation or the thread is interrupted for some unknown reason.

Specified by:

getDdsModelSynchronously in interface IDdsLanguageModel

Returns:

isDdsModelParsed

public boolean isDdsModelParsed()

Has the DDS Model been parsed yet?

Specified by:

isDdsModelParsed in interface IDdsLanguageModel

Returns:

isDdsModelParsePending

public boolean isDdsModelParsePending()

Is there a DDS parse already in progress

Specified by:

isDdsModelParsePending in interface IDdsLanguageModel

parseDdsModel

public DdsModel parseDdsModel()

Parse the model

Returns:

getBidiTransform

public AS400BidiTransform getBidiTransform()

Get the JTOpen transform that is able transform between the BIDI representation on the iSeries and the representation in a Java String. Typically on the iSeries the data is in visual order but in Java Strings it is always in logical order. When IFile are downloaded they are transformed to logical. But the parser expects the source in the same order that it was entered on the iSeries.

hasSequenceNumbers

public boolean hasSequenceNumbers()

convertToAS400Layout

public String convertToAS400Layout(String text)

Convert given text to the ordering scheme of the iSeries

Parameters:

text -

convertToJavaLayout

public String convertToJavaLayout(String text)

Convert given text to the ordering scheme of the Java

Parameters:

text -

incrementallyUpdateModel

public boolean incrementallyUpdateModel(DdsChange change)

Update the model with the changed/inserted line If we could not do this return true

Specified by:

incrementallyUpdateModel in interface IDdsLanguageModel

Parameters:

change - - what change occurred it encapsulates lineNumber - the line number of the line to be changed/inserted typeOfChange - the type of change of the line - an update or an insert

Returns:

true if the model has been refreshed since it cannot be updated incrementally

refreshModel

public void refreshModel()

Refresh the model based on the changed source in Lpex.

Specified by:

refreshModel in interface IDdsLanguageModel

getParseJobScheduler

public DdsModelLpexAdapter.ParseJobScheduler getParseJobScheduler()
