DirTree Tcl Reference Documentation

DirTree

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

set myDirTree [new CkDirTree]

Properties

BaseDir
string
# ckStr is a CkString
CkDirTree_get_BaseDir $myDirTree $ckStr
set strVal [CkDirTree_get_baseDir $myDirTree]
CkDirTree_put_BaseDir $myDirTree $strVal

Begin iterating from this directory.

top
DebugLogFilePath
string
# ckStr is a CkString
CkDirTree_get_DebugLogFilePath $myDirTree $ckStr
set strVal [CkDirTree_get_debugLogFilePath $myDirTree]
CkDirTree_put_DebugLogFilePath $myDirTree $strVal

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.

More Information and Examples
top
DoneIterating
boolean 1/0
set boolVal [CkDirTree_get_DoneIterating $myDirTree]

Set to 1 when the last file or sub-directory has been iterated.

top
FileSize32
integer
set intVal [CkDirTree_get_FileSize32 $myDirTree]

The file size of the current file in the iteration. (0 if it is a directory.)

top
FileSize64
(64-bit integer)
set int64Val [CkDirTree_get_FileSize64 $myDirTree]

The file size as a 64-bit integer of the current file in the iteration. (0 if it is a directory.)

top
FileSizeStr
string
# ckStr is a CkString
CkDirTree_get_FileSizeStr $myDirTree $ckStr
set strVal [CkDirTree_get_fileSizeStr $myDirTree]
Introduced in version 9.5.0.88

The file size of the current file in the iteration as a decimal string. (0 if it is a directory.)

top
FullPath
string
# ckStr is a CkString
CkDirTree_get_FullPath $myDirTree $ckStr
set strVal [CkDirTree_get_fullPath $myDirTree]

The absolute directory path of the current file or sub-directory.

top
FullUncPath
string
# ckStr is a CkString
CkDirTree_get_FullUncPath $myDirTree $ckStr
set strVal [CkDirTree_get_fullUncPath $myDirTree]

The absolute UNC directory path of the current file or sub-directory.

top
IsDirectory
boolean 1/0
set boolVal [CkDirTree_get_IsDirectory $myDirTree]

1 if the current position is a sub-directory, 0 if it is a file.

top
LastErrorHtml
string
# ckStr is a CkString
CkDirTree_get_LastErrorHtml $myDirTree $ckStr
set strVal [CkDirTree_get_lastErrorHtml $myDirTree]

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.

top
LastErrorText
string
# ckStr is a CkString
CkDirTree_get_LastErrorText $myDirTree $ckStr
set strVal [CkDirTree_get_lastErrorText $myDirTree]

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.

top
LastErrorXml
string
# ckStr is a CkString
CkDirTree_get_LastErrorXml $myDirTree $ckStr
set strVal [CkDirTree_get_lastErrorXml $myDirTree]

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.

top
LastMethodSuccess
boolean 1/0
set boolVal [CkDirTree_get_LastMethodSuccess $myDirTree]
CkDirTree_put_LastMethodSuccess $myDirTree $boolVal

Indicates the success or failure of the most recent method call: 1 means success, 0 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.

top
Recurse
boolean 1/0
set boolVal [CkDirTree_get_Recurse $myDirTree]
CkDirTree_put_Recurse $myDirTree $boolVal

If 1, the iteration will be recursive. If 0 the iteration is non-recursive. The default value is 1.

top
RelativePath
string
# ckStr is a CkString
CkDirTree_get_RelativePath $myDirTree $ckStr
set strVal [CkDirTree_get_relativePath $myDirTree]

The relative directory path of the current file or sub-directory. (Relative to the BaseDir)

top
Utf8
boolean 1/0
set boolVal [CkDirTree_get_Utf8 $myDirTree]
CkDirTree_put_Utf8 $myDirTree $boolVal

When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.

top
VerboseLogging
boolean 1/0
set boolVal [CkDirTree_get_VerboseLogging $myDirTree]
CkDirTree_put_VerboseLogging $myDirTree $boolVal

If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

top
Version
string
# ckStr is a CkString
CkDirTree_get_Version $myDirTree $ckStr
set strVal [CkDirTree_get_version $myDirTree]

Version of the component/library, such as "10.1.0"

Methods

AdvancePosition
set status [CkDirTree_AdvancePosition]

Advances the current position in the directory tree traversal to the next file or sub-directory.

Important: If AdvancePosition returns 0, 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 1, then the 0 return value is not an error, but instead indicates that the end has been reached.

Returns 1 for success, 0 for failure.

top
BeginIterate
set status [CkDirTree_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 0, 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 1, then the 0 return value is not an error, but instead indicates 0 files/directories.

Returns 1 for success, 0 for failure.
