Detailed Description

Base class for definition-use chain objects.

This class provides a thread safe pointer type to reference duchain objects while the DUChain mutex is not held (

Constructor & Destructor Documentation

DUChainBase() [1/4]

KDevelop::DUChainBase::DUChainBase ( const RangeInRevision &  range )

explicit

Constructor.

Parameters

range

range of the alias declaration's identifier

Definition at line 44 of file duchainbase.cpp.

~DUChainBase()

KDevelop::DUChainBase::~DUChainBase ( )

virtual

Destructor.

Definition at line 94 of file duchainbase.cpp.

DUChainBase() [2/4]

KDevelop::DUChainBase::DUChainBase ( DUChainBaseData &  dd )

explicit

Definition at line 57 of file duchainbase.cpp.

DUChainBase() [3/4]

KDevelop::DUChainBase::DUChainBase ( DUChainBase &  rhs )

protected

Creates a duchain object that uses the data of the given one, and will not delete it on destruction.

The data will be shared, and this object must be deleted before the given one is.

Definition at line 62 of file duchainbase.cpp.

DUChainBase() [4/4]

KDevelop::DUChainBase::DUChainBase ( DUChainBaseData &  dd, const RangeInRevision &  range  )

protected

Constructor for copy constructors in subclasses.

Parameters

dd	data to use.
range	text range which this object covers.

Definition at line 51 of file duchainbase.cpp.

Member Function Documentation

createRangeMoving()

PersistentMovingRange::Ptr KDevelop::DUChainBase::createRangeMoving

(

)

const

Returns the range assigned to this object, transformed into the current revision of the document.

The returned object is unique at each call, so you can use it and change it in whatever way you want.

Warning

This must only be called from the foreground thread, or with the foreground lock acquired.

Definition at line 170 of file duchainbase.cpp.

makeDynamic()

void KDevelop::DUChainBase::makeDynamic

(

)

After this was called, the data-pointer is dynamic. It is cloned if needed.

Definition at line 132 of file duchainbase.cpp.

operator=()

DUChainBase& KDevelop::DUChainBase::operator= ( const DUChainBase &  rhs )

delete

range()

RangeInRevision KDevelop::DUChainBase::range

(

)

const

Returns the range assigned to this object, in the document revision when this document was last parsed.

Definition at line 152 of file duchainbase.cpp.

rangeInCurrentRevision()

KTextEditor::Range KDevelop::DUChainBase::rangeInCurrentRevision

(

)

const

Returns the range assigned to this object, transformed into the current revision of the document.

Warning

This must only be called from the foreground thread, or with the foreground lock acquired.

Definition at line 157 of file duchainbase.cpp.

rebuildDynamicData()

void KDevelop::DUChainBase::rebuildDynamicData ( DUContext *  parent, uint  ownIndex  )

protectedvirtual

Called after loading to rebuild the dynamic data. If this is a context, this should recursively work on all sub-contexts.

Reimplemented in KDevelop::TopDUContext.

Definition at line 126 of file duchainbase.cpp.

setData()

void KDevelop::DUChainBase::setData ( DUChainBaseData *  data, bool  constructorCalled = true  )

virtual

This must only be used to change the storage-location or storage-kind(dynamic/constant) of the data, but the data must always be equal!

Definition at line 77 of file duchainbase.cpp.

setRange()

void KDevelop::DUChainBase::setRange

(

const RangeInRevision &

range

)

Changes the range assigned to this object, in the document revision when this document is parsed.

Definition at line 224 of file duchainbase.cpp.

topContext()

TopDUContext * KDevelop::DUChainBase::topContext ( ) const

virtual

Determine the top context to which this object belongs.

Todo:

Move the reference to the top-context right into this class, as it's common to all inheriters

Reimplemented in KDevelop::DUContext, KDevelop::Problem, KDevelop::ParsingEnvironmentFile, KDevelop::TopDUContext, and KDevelop::Declaration.

Definition at line 105 of file duchainbase.cpp.

transformFromLocalRevision() [1/2]

KTextEditor::Cursor KDevelop::DUChainBase::transformFromLocalRevision

(

const CursorInRevision &

cursor

)

const

transformFromLocalRevision() [2/2]

KTextEditor::Range KDevelop::DUChainBase::transformFromLocalRevision

(

const RangeInRevision &

range

)

const

transformToLocalRevision() [1/2]

CursorInRevision KDevelop::DUChainBase::transformToLocalRevision

(

const KTextEditor::Cursor &

cursor

)

const

Transforms the given cursor in the current document revision to its according position in the parsed document containing this duchain object.

The resulting cursor will be directly comparable to the non-translated range() members in the duchain, but only for one duchain locking cycle.

Warning

This must only be called from the foreground thread, or with the foreground lock acquired.

Definition at line 176 of file duchainbase.cpp.

transformToLocalRevision() [2/2]

RangeInRevision KDevelop::DUChainBase::transformToLocalRevision

(

const KTextEditor::Range &

range

)

const

Transforms the given range in the current document revision to its according position in the parsed document containing this duchain object.

The resulting cursor will be directly comparable to the non-translated range() members in the duchain, but only for one duchain locking cycle.

Warning

This must only be called from the foreground thread, or with the foreground lock acquired.

Definition at line 188 of file duchainbase.cpp.

url()

IndexedString KDevelop::DUChainBase::url ( ) const

virtual

Reimplemented in KDevelop::Problem, KDevelop::ParsingEnvironmentFile, and KDevelop::TopDUContext.

Definition at line 68 of file duchainbase.cpp.

weakPointer()

const QExplicitlySharedDataPointer< DUChainPointerData > & KDevelop::DUChainBase::weakPointer

(

)

const

Returns a special pointer that can be used to track the existence of a du-chain object across locking-cycles.

Member Data Documentation

d_ptr

DUChainBaseData* KDevelop::DUChainBase::d_ptr
