StringArray Java 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

CkStringArray obj = new CkStringArray();

Properties

Count
int get_Count();

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
boolean get_Crlf();
void put_Crlf(boolean 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);
String debugLogFilePath();
void put_DebugLogFilePath(String newVal);

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);
String lastErrorHtml();

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);
String lastErrorText();

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);
String 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.

top
LastMethodSuccess
boolean get_LastMethodSuccess();
void put_LastMethodSuccess(boolean 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();

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

top
Trim
boolean get_Trim();
void put_Trim(boolean 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
boolean get_Unique();
void put_Unique(boolean 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
VerboseLogging
boolean get_VerboseLogging();
void put_VerboseLogging(boolean 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);
String version();

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

Methods

Append
boolean Append(String str);

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

Returns true for success, false for failure.

top
AppendSerialized
boolean AppendSerialized(String 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();

Remove all strings from the internal collection.

top
Contains
boolean Contains(String str);

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

top
Find
int Find(String 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(String 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
boolean GetString(int index, CkString outStr);
String 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, String str);

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

top
LastString
boolean LastString(CkString outStr);
String lastString();

Returns the last string in the internal collection.

Returns true for success, false for failure.

top
LoadFromFile
boolean LoadFromFile(String 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
boolean LoadFromFile2(String path, String 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.

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(String 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.

top
LoadTaskResult
boolean LoadTaskResult(CkTask task);
Introduced in version 9.5.0.52

Loads the string collection from a completed asynchronous task.

Returns true for success, false for failure.

top
Pop
boolean Pop(CkString outStr);
String pop();

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

Returns true for success, false for failure.

top
Prepend
void Prepend(String str);

Adds a string to the beginning of the internal collection.

top
Remove
void Remove(String str);

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

top
RemoveAt
boolean RemoveAt(int index);

Removes the string at a particular index.

Returns true for success, false for failure.

top
SaveToFile
boolean SaveToFile(String 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.

top
SaveToFile2
boolean SaveToFile2(String saveToPath, String 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.

top
SaveToText
boolean SaveToText(CkString outStr);
String saveToText();

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

Returns true for success, false for failure.

top
Serialize
boolean Serialize(CkString outStr);
String serialize();

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.
