Detailed Description

utility to locate resource files.

VTK based application often need to locate resource files, such configuration files, Python modules, etc. vtkResourceFileLocator provides methods that can be used to locate such resource files at runtime.

Using Locate, one can locate files relative to an anchor directory such as the executable directory, or the library directory.

GetLibraryPathForSymbolUnix and GetLibraryPathForSymbolWin32 methods can be used to locate the library that provides a particular symbol. For example, this is used by vtkPythonInterpreter to ensure that the vtk Python package is located relative the VTK libraries, irrespective of the application location.

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ SetPrintDebugInformation()

void vtkResourceFileLocator::SetPrintDebugInformation ( bool )

Enable/disable printing of testing of various path during Locate to stdout.

Deprecated:: Instead use SetLogVerbosity to specify the verbosity at which this instance should log trace information. Default is vtkLogger::VERBOSITY_TRACE.

◆ GetPrintDebugInformation()

bool vtkResourceFileLocator::GetPrintDebugInformation ( )

Enable/disable printing of testing of various path during Locate to stdout.

Deprecated:: Instead use SetLogVerbosity to specify the verbosity at which this instance should log trace information. Default is vtkLogger::VERBOSITY_TRACE.

◆ PrintDebugInformationOn()

void vtkResourceFileLocator::PrintDebugInformationOn ( )

Enable/disable printing of testing of various path during Locate to stdout.

Deprecated:: Instead use SetLogVerbosity to specify the verbosity at which this instance should log trace information. Default is vtkLogger::VERBOSITY_TRACE.

◆ PrintDebugInformationOff()

void vtkResourceFileLocator::PrintDebugInformationOff ( )

Enable/disable printing of testing of various path during Locate to stdout.

Deprecated:: Instead use SetLogVerbosity to specify the verbosity at which this instance should log trace information. Default is vtkLogger::VERBOSITY_TRACE.

◆ SetLogVerbosity()

virtual void vtkResourceFileLocator::SetLogVerbosity ( int )

virtual

The log verbosity to use when logging information about the resource searching.

Default is vtkLogger::VERBOSITY_TRACE.

◆ GetLogVerbosity()

virtual int vtkResourceFileLocator::GetLogVerbosity ( )

virtual

The log verbosity to use when logging information about the resource searching.

Default is vtkLogger::VERBOSITY_TRACE.

◆ Locate() [1/2]

virtual std::string vtkResourceFileLocator::Locate	(	const std::string &	anchor,
		const std::string &	landmark,
		const std::string &	defaultDir = `std::string()`
	)

virtual

Given a starting anchor directory, look for the landmark file relative to the anchor.

If found return the anchor. If not found, go one directory up and then look the landmark file again.

◆ Locate() [2/2]

virtual std::string vtkResourceFileLocator::Locate	(	const std::string &	anchor,
		const std::vector< std::string > &	landmark_prefixes,
		const std::string &	landmark,
		const std::string &	defaultDir = `std::string()`
	)

virtual

This variant is used to look for landmark relative to the anchor using additional prefixes for the landmark file.

For example, if you're looking for vtk/__init__.py, but it can be placed relative to your anchor location (let's say the executable directory), under "lib" or "lib/python", then use this variant with "lib", and "lib/python" passed in as the landmark prefixes. On success, the returned value will be anchor + matching prefix.

◆ GetLibraryPathForSymbolUnix()

static std::string vtkResourceFileLocator::GetLibraryPathForSymbolUnix ( const char * symbolname )

static

Returns the name of the library providing the symbol.

For example, if you want to locate where the VTK libraries located call GetLibraryPathForSymbolUnix("GetVTKVersion") on Unixes and GetLibraryPathForSymbolWin32(GetVTKVersion) on Windows. Alternatively, you can simply use the vtkGetLibraryPathForSymbol(GetVTKVersion) macro that makes the appropriate call as per the current platform.

◆ GetLibraryPathForSymbolWin32()

static std::string vtkResourceFileLocator::GetLibraryPathForSymbolWin32 ( const void * fptr )

static

Returns the name of the library providing the symbol.

For example, if you want to locate where the VTK libraries located call GetLibraryPathForSymbolUnix("GetVTKVersion") on Unixes and GetLibraryPathForSymbolWin32(GetVTKVersion) on Windows. Alternatively, you can simply use the vtkGetLibraryPathForSymbol(GetVTKVersion) macro that makes the appropriate call as per the current platform.
