StringArray C++ Reference Documentation

CkStringArray

Current Version: 10.1.2

Class/object for managing and manipulating collections of strings. Contains an ordered collection of strings.

Important: The Chilkat StringTable class is a better choice for a large number of strings.

Object Creation

// Local variable on the stack
CkStringArray obj;

// Dynamically allocate/delete
CkStringArray *pObj = new CkStringArray();
// ...
delete pObj;

Properties

Count
int get_Count(void);

The number of strings contained within the object's internal array (i.e. ordered collection).

Important: This is an object that contains a collection of strings. Although the class/object name includes the word "Array", it should not be confused with an array in the sense of the primitive array type used in a given programming language.

top
Crlf
bool get_Crlf(void);
void put_Crlf(bool newVal);

If true, strings are always automatically converted to use CRLF line endings. If false, strings are automatically converted to use bare LF line endings.

top
DebugLogFilePath
void get_DebugLogFilePath(CkString &str);
const char *debugLogFilePath(void);
void put_DebugLogFilePath(const char *ansiOrUtf8Str);

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.

top
LastErrorHtml
void get_LastErrorHtml(CkString &str);
const char *lastErrorHtml(void);

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
void get_LastErrorText(CkString &str);
const char *lastErrorText(void);

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
void get_LastErrorXml(CkString &str);
const char *lastErrorXml(void);

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
bool get_LastMethodSuccess(void);
void put_LastMethodSuccess(bool newVal);

Indicates the success or failure of the most recent method call: true means success, false 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
Length
int get_Length(void);

The number of strings contained within the internal collection. (Identical to the Count property.)

top
Trim
bool get_Trim(void);
void put_Trim(bool newVal);

If true, whitespace, including carriage-returns and linefeeds, are automatically removed from the beginning and end of a string when added to the collection.

top
Unique
bool get_Unique(void);
void put_Unique(bool newVal);

If true, then duplicates are not allowed. When an attempt is made to insert a string that already exists, the duplicate insertion is silently suppressed and no error is returned. The default value is false.

top
Utf8
bool get_Utf8(void);
void put_Utf8(bool newVal);

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

top
VerboseLogging
bool get_VerboseLogging(void);
void put_VerboseLogging(bool newVal);

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

top
Version
void get_Version(CkString &str);
const char *version(void);

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

Methods

Append
bool Append(const char *str);

Appends a string to the end of the internal ordered collection.

Returns true for success, false for failure.

top
AppendSerialized
bool AppendSerialized(const char *encodedStr);

Appends multiple strings to the end of the internal ordered collection. The encodedStr is what is returned from the Serialize method (see below).

Returns true for success, false for failure.

top
Clear
void Clear(void);

Remove all strings from the internal collection.

top
Contains
bool Contains(const char *str);

Returns true if the string is present in the internal collection. The string comparisons are case sensitive.

top
Find
int Find(const char *findStr, int startIndex);

Finds the index of the first string equal to findStr. The search begins at startIndex. If the string is not found, -1 is returned. The first string in the array is at index 0.

top
FindFirstMatch
int FindFirstMatch(const char *matchPattern, int startIndex);

Finds the first string that matches the matchPattern. The search begins at startIndex. If the string is not found, -1 is returned. The first string in the array is at index 0.

The matchPattern may contain zero or more asterisk chars, each of which matches 0 or more of any character.

top
GetString
bool GetString(int index, CkString &outStr);
const char *getString(int index);

Returns the string at an indexed location within the internal collection. The first string is located at index 0.

Returns true for success, false for failure.

top
GetStringLen
int GetStringLen(int index);

Returns Nth string's length, in characters. The first string is located at index 0.

top
InsertAt
void InsertAt(int index, const char *str);

Inserts a string into the internal collection at a specified index. Using index 0 will insert at the beginning.

top
LastString
bool LastString(CkString &outStr);
const char *lastString(void);

Returns the last string in the internal collection.

Returns true for success, false for failure.

top
LoadFromFile
bool LoadFromFile(const char *path);

Loads strings from a file (one per line) into the internal collection. It is assumed the file contains ANSI strings. To load from a file containing non-ANSI strings (such as utf-8), call LoadFromFile2 instead.

Note: This method appends the strings in path to the existing collection of strings contained in this object.

Returns true for success, false for failure.

top
LoadFromFile2
bool LoadFromFile2(const char *path, const char *charset);

Note: This method appends the strings in path to the existing collection of strings contained in this object.

Returns true for success, false for failure.

top
LoadFromText
void LoadFromText(const char *str);

Loads strings from an in-memory string (one per line) into the internal collection.

Note: This method appends the strings in str to the existing collection of strings contained in this object.
