DirTree Objective-C Reference Documentation
CkoDirTree
Current Version: 10.1.2
API for iterating over the files and sub-directories in a directory tree. The intent of this class is to provide a simplified, non-recursive way to iterate over an entire directory tree.
Object Creation
CkoDirTree *obj = [[CkoDirTree alloc] init];
Properties
BaseDir
DebugLogFilePath
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
DoneIterating
Set to YES when the last file or sub-directory has been iterated.
topFileSize32
The file size of the current file in the iteration. (0 if it is a directory.)
topFileSize64
The file size as a 64-bit integer of the current file in the iteration. (0 if it is a directory.)
topFileSizeStr
The file size of the current file in the iteration as a decimal string. (0 if it is a directory.)
topFullPath
The absolute directory path of the current file or sub-directory.
topFullUncPath
The absolute UNC directory path of the current file or sub-directory.
topIsDirectory
YES if the current position is a sub-directory, NO if it is a file.
topLastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Indicates the success or failure of the most recent method call: YES means success, NO means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topRecurse
If YES, the iteration will be recursive. If NO the iteration is non-recursive. The default value is YES.
topRelativePath
The relative directory path of the current file or sub-directory. (Relative to the BaseDir)
topVerboseLogging
If set to YES, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is NO. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Methods
AdvancePosition
Advances the current position in the directory tree traversal to the next file or sub-directory.
Important: If AdvancePosition returns NO, it can be an error, or it could be that there are no more files and directories. To distinguish between the two cases, examine the DoneIterating property. If DoneIterating is YES, then the NO return value is not an error, but instead indicates that the end has been reached.
Returns YES for success, NO for failure.
BeginIterate
Begins a directory tree traversal. After calling this method, the various property values such as Fullpath, FileSize32, etc. can be retrieved for the 1st file / sub-directory in the traversal.
Important: If BeginIterate returns NO, it can be an error, or it could be that there are 0 files and directories. To distinguish between the two cases, examine the DoneIterating property. If DoneIterating is YES, then the NO return value is not an error, but instead indicates 0 files/directories.
Returns YES for success, NO for failure.
