CkStringArray Java Reference Documentation

CkStringArray

Current Version: 9.5.0.75

Class/object for managing and manipulating collections of strings. Contains an ordered collection 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, 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
void get_LastErrorHtml(CkString str);
String lastErrorHtml();

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
void get_LastErrorText(CkString str);
String lastErrorText();

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
void get_LastErrorXml(CkString str);
String lastErrorXml();

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 get_LastMethodSuccess();
void put_LastMethodSuccess(boolean 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.

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 "9.5.0.63"

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.

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.

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.

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

Loads the string collection from a completed asynchronous task.

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.

top
ReplaceAt
void ReplaceAt(int index, String str);

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).

top
Subtract
void Subtract(CkStringArray stringArrayObj);

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

top
Union
void Union(CkStringArray 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.
