StringTable Tcl Reference Documentation

StringTable

Current Version: 9.5.0.73

A memory efficient class for holding a large number of strings (accessible by index). The primary use is as a read-only table of strings that is built once and then used by the application.

This class is introduced in Chilkat v9.5.0.62.

Object Creation

set myStringTable [new CkStringTable]

Properties

Count
integer
set intVal [CkStringTable_get_Count $myStringTable]
Introduced in version 9.5.0.62

The number of strings in the table.

top
DebugLogFilePath
string
# ckStr is a CkString
CkStringTable_get_DebugLogFilePath $myStringTable $ckStr
set strVal [CkStringTable_get_debugLogFilePath $myStringTable]
CkStringTable_put_DebugLogFilePath $myStringTable $strVal

If set to a file path, causes each Chilkat method or property call to automatically append it's LastErrorText to the specified log file. The information is appended such that if a hang or crash occurs, it is possible to see the context in which the problem occurred, as well as a history of all Chilkat calls up to the point of the problem. The VerboseLogging property can be set to provide more detailed information.

This property is typically used for debugging the rare cases where a Chilkat method call hangs or generates an exception that halts program execution (i.e. crashes). A hang or crash should generally never happen. The typical causes of a hang are:

  1. a timeout related property was set to 0 to explicitly indicate that an infinite timeout is desired,
  2. the hang is actually a hang within an event callback (i.e. it is a hang within the application code), or
  3. there is an internal problem (bug) in the Chilkat code that causes the hang.

top
LastErrorHtml
string
# ckStr is a CkString
CkStringTable_get_LastErrorHtml $myStringTable $ckStr
set strVal [CkStringTable_get_lastErrorHtml $myStringTable]

Provides information in HTML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorText
string
# ckStr is a CkString
CkStringTable_get_LastErrorText $myStringTable $ckStr
set strVal [CkStringTable_get_lastErrorText $myStringTable]

Provides information in plain-text format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastErrorXml
string
# ckStr is a CkString
CkStringTable_get_LastErrorXml $myStringTable $ckStr
set strVal [CkStringTable_get_lastErrorXml $myStringTable]

Provides information in XML format about the last method/property called. If a method call returns a value indicating failure, or behaves unexpectedly, examine this property to get more information.

top
LastMethodSuccess
boolean 1/0
set boolVal [CkStringTable_get_LastMethodSuccess $myStringTable]
CkStringTable_put_LastMethodSuccess $myStringTable $boolVal
Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of 1 indicates success, a value of 0 indicates failure. This property is automatically set for method calls. It is not modified by property accesses. The property is automatically set to indicate success for the following types of method calls:

  • Any method that returns a string.
  • Any method returning a Chilkat object, binary bytes, or a date/time.
  • Any method returning a standard boolean status value where success = 1 and failure = 0.
  • Any method returning an integer where failure is defined by a return value less than zero.

Note: Methods that do not fit the above requirements will always set this property equal to 1. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

top
Utf8
boolean 1/0
set boolVal [CkStringTable_get_Utf8 $myStringTable]
CkStringTable_put_Utf8 $myStringTable $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 [CkStringTable_get_VerboseLogging $myStringTable]
CkStringTable_put_VerboseLogging $myStringTable $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.

Version
string
# ckStr is a CkString
CkStringTable_get_Version $myStringTable $ckStr
set strVal [CkStringTable_get_version $myStringTable]

Version of the component/library, such as "9.5.0.63"

Methods

Append
# value is a string
set status [CkStringTable_Append $value]
Introduced in version 9.5.0.62

Appends a string to the table.

Returns 1 for success, 0 for failure.

top
AppendFromFile
# maxLineLen is an integer
# charset is a string
# path is a string
set status [CkStringTable_AppendFromFile $maxLineLen $charset $path]
Introduced in version 9.5.0.62

Appends strings, one per line, from a file. Each line in the path should be no longer than the length specified in maxLineLen. The charset indicates the character encoding of the contents of the file, such as "utf-8", "iso-8859-1", "Shift_JIS", etc.

Returns 1 for success, 0 for failure.

top
AppendFromSb
# sb is a CkStringBuilder
set status [CkStringTable_AppendFromSb $sb]
Introduced in version 9.5.0.62

Appends strings, one per line, from the contents of a StringBuilder object.

Returns 1 for success, 0 for failure.

More Information and Examples
top
Clear
CkStringTable_Clear
Introduced in version 9.5.0.62

Removes all the strings from the table.

top
IntAt
# index is an integer
set retInt [CkStringTable_IntAt $index]
Introduced in version 9.5.0.63

Returns the Nth string in the table, converted to an integer value. The index is 0-based. (The first string is at index 0.) Returns -1 if no string is found at the specified index. Returns 0 if the string at the specified index exist, but is not an integer.

top
SaveLastError
# path is a string
set status [CkStringTable_SaveLastError $path]

Saves the last-error information (the contents of LastErrorXml) to an XML formatted file.

Returns 1 for success, 0 for failure.

top
SaveToFile
# charset is a string
# bCrlf is a boolean
# path is a string
set status [CkStringTable_SaveToFile $charset $bCrlf $path]
Introduced in version 9.5.0.62

Saves the string table to a file. The charset is the character encoding to use, such as "utf-8", "iso-8859-1", "windows-1252", "Shift_JIS", "gb2312", etc. If bCrlf is 1, then CRLF line endings are used, otherwise LF-only line endings are used.

Returns 1 for success, 0 for failure.

top
SplitAndAppend
# inStr is a string
# delimiterChar is a string
# exceptDoubleQuoted is a boolean
# exceptEscaped is a boolean
set status [CkStringTable_SplitAndAppend $inStr $delimiterChar $exceptDoubleQuoted $exceptEscaped]
Introduced in version 9.5.0.62

Splits a string into parts based on a single character delimiterChar. If exceptDoubleQuoted is 1, then the delimiter char found between double quotes is not treated as a delimiter. If exceptEscaped is 1, then an escaped (with a backslash) delimiter char is not treated as a delimiter.

Returns 1 for success, 0 for failure.

top
StringAt
# index is an integer
# outStr is a CkString (output)
set status [CkStringTable_StringAt $index $outStr]
set retStr [CkStringTable_stringAt $myStringTable $index]
Introduced in version 9.5.0.62

Returns the Nth string in the table. The index is 0-based. (The first string is at index 0.)
