Interface ISourceLookupDirector

All Superinterfaces:
IPersistableSourceLocator, IPersistableSourceLocator2, ISourceLocator
All Known Implementing Classes:
AbstractSourceLookupDirector

public interface ISourceLookupDirector
extends IPersistableSourceLocator2

A source lookup director directs the source lookup process among a set of participants and source containers.

Clients may implement this interface. An astract implementation is provided by AbstractSourceLookupDirector, which clients should subclass.

Since:
3.0

Method Summary
 void addParticipants(ISourceLookupParticipant[] participants)
          Adds the given source lookup participants to this director.
 void clearSourceElements(Object element)
          Clears any source lookup results associated with the given debug artifact, such that a subsequent lookup will force a new search to be performed.
 Object[] findSourceElements(Object object)
          Returns a collection of source elements corresponding to the given debug artifact (for example, a stack frame or breakpoint).
 String getId()
          Returns the identifier of this type of source locator.
 ILaunchConfiguration getLaunchConfiguration()
          Returns the launch configuration associated with this source lookup director, or null if none.
 ISourceLookupParticipant[] getParticipants()
          Returns the source lookup participants currently registered with this director, possibly an empty collection.
 ISourceContainer[] getSourceContainers()
          Returns the source containers currently registered with this director, possibly an empty collection.
 Object getSourceElement(Object element)
          Returns a source element that corresponds to the given debug artifact, or null if a source element could not be located.
 ISourcePathComputer getSourcePathComputer()
          Returns the source path computer to use with this source lookup director, possibly null.
 void initializeParticipants()
          Notifies this source lookup director that it should initialize its set of source lookup participants.
 boolean isFindDuplicates()
          Returns whether to search exhaustively for all source elements with the same name in all registered source containers, or whether to stop searching when the first source element matching the required name is found.
 void removeParticipants(ISourceLookupParticipant[] participants)
          Removes the given source lookup participants from this director.
 void setFindDuplicates(boolean findDuplicates)
          Sets whether to search exhaustively for all source elements with the same name in all registered source containers, or whether to stop searching when the first source element matching the required name is found.
 void setSourceContainers(ISourceContainer[] containers)
          Sets the source containers this source lookup director should search when looking for source, possibly an empty collection.
 void setSourcePathComputer(ISourcePathComputer computer)
          Sets the source path computer for this source lookup director.
 boolean supportsSourceContainerType(ISourceContainerType type)
          Returns whether this source director supports the given type of source location.

Method Detail

getLaunchConfiguration

public ILaunchConfiguration getLaunchConfiguration()
Returns the launch configuration associated with this source lookup director, or null if none.

Returns:
the launch configuration associated with this source lookup director, or null if none

getParticipants

public ISourceLookupParticipant[] getParticipants()
Returns the source lookup participants currently registered with this director, possibly an empty collection.

Returns:
the source lookup participants currently registered with this director, possibly an empty collection

getSourceContainers

public ISourceContainer[] getSourceContainers()
Returns the source containers currently registered with this director, possibly an empty collection.

Returns:
the source containers currently registered with this director, possibly an empty collection

setSourceContainers

public void setSourceContainers(ISourceContainer[] containers)
Sets the source containers this source lookup director should search when looking for source, possibly an empty collection.

Parameters:
containers - the source containers this source lookup director should search when looking for source, possibly an empty collection

isFindDuplicates

public boolean isFindDuplicates()
Returns whether to search exhaustively for all source elements with the same name in all registered source containers, or whether to stop searching when the first source element matching the required name is found.

Returns:
whether to search exhaustively for all source elements with the same name

setFindDuplicates

public void setFindDuplicates(boolean findDuplicates)
Sets whether to search exhaustively for all source elements with the same name in all registered source containers, or whether to stop searching when the first source element matching the required name is found.

Parameters:
findDuplicates - whether to search exhaustively for all source elements with the same name

initializeParticipants

public void initializeParticipants()
Notifies this source lookup director that it should initialize its set of source lookup participants.


supportsSourceContainerType

public boolean supportsSourceContainerType(ISourceContainerType type)
Returns whether this source director supports the given type of source location.

Parameters:
type - source container type
Returns:
whether this source director supports the given type of source location

clearSourceElements

public void clearSourceElements(Object element)
Clears any source lookup results associated with the given debug artifact, such that a subsequent lookup will force a new search to be performed.

Parameters:
element - debug artifact to clear source lookup results for

addParticipants

public void addParticipants(ISourceLookupParticipant[] participants)
Adds the given source lookup participants to this director.

Parameters:
participants - participants to add

removeParticipants

public void removeParticipants(ISourceLookupParticipant[] participants)
Removes the given source lookup participants from this director.

Parameters:
participants - participants to remove

getId

public String getId()
Returns the identifier of this type of source locator.

Returns:
the identifier of this type of source locator

getSourcePathComputer

public ISourcePathComputer getSourcePathComputer()
Returns the source path computer to use with this source lookup director, possibly null. By default, the source path computer returned is the one associated with this director's launch configuration's type. However, the source path computer can be specified programmatically by calling setSourcePathComputer(...).

Returns:
the source path computer to use with this source lookup director, possibly null

setSourcePathComputer

public void setSourcePathComputer(ISourcePathComputer computer)
Sets the source path computer for this source lookup director. This method can be used to override the default source path computer for a launch configuration type. When null is specified the default source path computer will be used (i.e. the one assocaited with this director's launch configuration's type).

Parameters:
computer - source path computer or null

findSourceElements

public Object[] findSourceElements(Object object)
                            throws CoreException
Returns a collection of source elements corresponding to the given debug artifact (for example, a stack frame or breakpoint). Returns an empty collection if no source elements are found. This participant's source lookup director specifies if duplicate source elements should be searched for, via isFindDuplicates(). When false the returned collection should contain at most one source element.

Parameters:
object - the debug artifact for which source needs to be found (e.g., stack frame)
Returns:
a collection of source elements corresponding to the given debug artifact, possibly empty
Throws:
CoreException - if an exception occurrs while searching for source

getSourceElement

public Object getSourceElement(Object element)
Returns a source element that corresponds to the given debug artifact, or null if a source element could not be located. This is a generalization of getSourceElement(IStackFrame) to allow source to be found for other types of elements.

Parameters:
element - the debug artifact for which to locate source
Returns:
an object representing a source element.
