Class sh::filesystem::FilesystemOperationTransfers::OperationStepClass

class sh::filesystem::FilesystemOperationTransfers::OperationStepClass : public sh::filesystem::FilesystemOperationTransfers::OperationStep

A base class for all implementations.

They are used from inside FilesystemOperationTransfers::executestepqueue.

Subclassed by sh::filesystem::FilesystemOperationTransfers::OperationStep_ApplyDirectoryDetails, sh::filesystem::FilesystemOperationTransfers::OperationStep_CopyDirectory, sh::filesystem::FilesystemOperationTransfers::OperationStep_CopyFile, sh::filesystem::FilesystemOperationTransfers::OperationStep_CopyLink, sh::filesystem::FilesystemOperationTransfers::OperationStep_DeleteItem, sh::filesystem::FilesystemOperationTransfers::OperationStep_RenameItem

Public Types

enum ConflictResolution

Enumeration of ways how to resolve a filesystem conflict.

Values:

enumerator Skip

Skip this element.

enumerator OverwriteDestination

Overwrite the destination.

enumerator RenameDestinationBefore

Rename the file at the destination before transferring.

enumerator UseDifferentDestinationName

Transfer to another destination filename.

enumerator MergeDirectories

Merge source into destination directory (recursively).

enumerator Unresolved

No strategy.

enumerator Indirect

Indirectly solved. Only set by the engine.

Public Functions

OperationStepClass(FilesystemOperationTransfers *transfers, std::shared_ptr<const sh::filesystem::Eurl> source, std::shared_ptr<const Eurl> destination, QList<OperationStepClass*> withExpansion)

void execute(Operation *op) = 0

Implement this and handle the execution part of this step here.

QList<OperationStepClass*> expand()

Implement this and handle the expansion part of this step here.

bool checkconflicts(Operation *op)

Implement this for customizing the conflict checking.

bool hasOwnProgressIncreaseHandling()

If it takes care on its own to signal increases in the transfer progress.

void _unexpand(QList<OperationStepClass*> *intlist)

Bookkeeping in FilesystemOperationTransfers.

void _expand(QList<OperationStepClass*> *intlist)

Bookkeeping in FilesystemOperationTransfers.

~OperationStepClass()

QList<QPair<sh::filesystem::DetailColumn*, QVariant>> getFileDetails(sh::filesystem::Operation *op, std::shared_ptr<const sh::filesystem::Eurl> source)

void applyFileDetails(sh::filesystem::Operation *op, QList<QPair<sh::filesystem::DetailColumn*, QVariant>> values, std::shared_ptr<const sh::filesystem::Eurl> destination)

QString conflictDescription()

The description of the conflict (if any) as text.

ConflictResolution conflictResolution()

The currently chosen conflict resolution.

QString conflictResolution_renameDestinationBeforeTo()

Returns new destination name (if current conflict resolution is ConflictResolution::RenameDestinationBefore).

QString conflictResolution_differentDestinationNameTo()

Returns new destination name (if current conflict resolution is ConflictResolution::UseDifferentDestinationName).

std::shared_ptr<const sh::filesystem::Eurl> source()

Returns the source location to be transferred (if specified).

std::shared_ptr<const sh::filesystem::Eurl> originalDestination()

Returns the destination location (if specified).

This is the complete target path, never the parent directory of the new element.

This is the original destination location. See also effectiveDestination.

std::shared_ptr<const sh::filesystem::Eurl> effectiveDestination()

Returns the real destination location with conflict resolution applied.

int sourcetype()

Returns the node type of the source.

Should be overwritten in subclasses whenever it can determine the source type faster than the infrastructure.

void setConflictResolve_Skip()

Set conflict resolution to ConflictResolution::Skip.

void setConflictResolve_OverwriteDestination()

Set conflict resolution to ConflictResolution::OverwriteDestination.

void setConflictResolve_RenameDestinationBefore(QString newname)

Set conflict resolution to ConflictResolution::RenameDestinationBefore.

void setConflictResolve_UseDifferentDestinationName(QString newname)

Set conflict resolution to ConflictResolution::UseDifferentDestinationName.

void setConflictResolve_MergeDirectories()

Set conflict resolution to ConflictResolution::MergeDirectories.

See also setConflictResolve_MergeDirectories_isAllowed.

bool setConflictResolve_MergeDirectories_checkAllowed()

Checks if conflict resolution ConflictResolution::MergeDirectories is allowed.
