CkStringArrayW Unicode C++ Reference Documentation

CkStringArrayW

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

Properties

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.

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.

void get_DebugLogFilePath(CkString &str);
const wchar_t *debugLogFilePath(void);
void put_DebugLogFilePath(const wchar_t *str);

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.

void get_LastErrorHtml(CkString &str);
const wchar_t *lastErrorHtml(void);

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.

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

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.

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

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.

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

Introduced in version 9.5.0.52

Indicate whether the last method call succeeded or failed. A value of true indicates success, a value of false 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 = true and failure = false.
  • 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 true. For example, a method that returns no value (such as a "void" in C++) will technically always succeed.

int get_Length(void);

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

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.

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.

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.

void get_Version(CkString &str);
const wchar_t *version(void);

Version of the component/library, such as "9.4.1.42"

Methods

bool Append(const wchar_t *str);

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

Returns true for success, false for failure.

bool AppendSerialized(const wchar_t *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.

void Clear(void);

Remove all strings from the internal collection.

bool Contains(const wchar_t *str);

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

int Find(const wchar_t *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.

int FindFirstMatch(const wchar_t *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.

bool GetString(int index, CkString &outStr);
const wchar_t *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.

int GetStringLen(int index);

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

void InsertAt(int index, const wchar_t *str);

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

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

Returns the last string in the internal collection.

Returns true for success, false for failure.

bool LoadFromFile(const wchar_t *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.

Returns true for success, false for failure.

bool LoadFromFile2(const wchar_t *path, const wchar_t *charset);

Loads strings from a file (one per line) into the internal collection. The charset specifies the character encoding (such as utf-8) of the strings contained in the file.

Returns true for success, false for failure.

void LoadFromText(const wchar_t *str);

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

bool LoadTaskResult(CkTaskW &task);

Introduced in version 9.5.0.52

Loads the string collection from a completed asynchronous task.

Returns true for success, false for failure.

bool Pop(CkString &outStr);
const wchar_t *pop(void);

Returns the last string and removes it from the internal collection.

Returns true for success, false for failure.

void Prepend(const wchar_t *str);

Adds a string to the beginning of the internal collection.

void Remove(const wchar_t *str);

Removes all strings equal to the string argument from the internal collection.

bool RemoveAt(int index);

Removes the string at a particular index.

void ReplaceAt(int index, const wchar_t *str);

Introduced in version 9.5.0.52

Replaces the string at a specified index.

bool SaveLastError(const wchar_t *path);

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

Returns true for success, false for failure.

bool SaveNthToFile(int index, const wchar_t *saveToPath);

Saves the Nth string in the collection to a file.

Returns true for success, false for failure.

bool SaveToFile(const wchar_t *path);

Saves the collection of strings to a file, one string per line. Strings are saved using the ANSI charset. (Call SaveToFile2 to specify a charset, such as "utf-8")

Returns true for success, false for failure.

bool SaveToFile2(const wchar_t *saveToPath, const wchar_t *charset);

Saves the collection of strings to a file, one string per line. Strings are saved using the specified charset.

Returns true for success, false for failure.

bool SaveToText(CkString &outStr);
const wchar_t *saveToText(void);

Writes the collection of strings to a single string, one per line (separated by CRLF line endings).

Returns true for success, false for failure.

bool Serialize(CkString &outStr);
const wchar_t *serialize(void);

Returns an string which is an encoded representation of all the strings in the collection. The string collection can be re-created by calling the AppendSerialized method.

Returns true for success, false for failure.

void Sort(bool ascending);

Sorts the strings in the collection in ascending or descending order. To sort in ascending order, set ascending to true, otherwise set ascending equal to false.

void SplitAndAppend(const wchar_t *str, const wchar_t *boundary);

Splits a string at a character or substring boundary and adds each resulting string to the internal collection.

bool StrAt(int index, CkString &outStr);
const wchar_t *strAt(int index);

Returns the string at a specific index.

Returns true for success, false for failure.

void Subtract(CkStringArrayW &stringArrayObj);

Subtracts the strings contained within stringArrayObj from the caller's internal collection.

void Union(CkStringArrayW &stringArrayObj);

Performs the union set-operator. The result is that the caller will have a string collection that is the union of itself and stringArrayObj.
