StringArray PureBasic Reference Documentation

StringArray

Current Version: 9.5.0.98

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

obj.i = CkStringArray::ckCreate()

; Make sure to dispose of the object when finished like this:
CkStringArray::ckDispose(obj);

Properties

Count
Declare.i ckCount(obj.i) ; (read-only)

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
Declare.i ckCrlf(obj.i)
Declare setCkCrlf(obj.i, value.i)

If 1, strings are always automatically converted to use CRLF line endings. If 0, strings are automatically converted to use bare LF line endings.

top
DebugLogFilePath
Declare.s ckDebugLogFilePath(obj.i)
Declare setCkDebugLogFilePath(obj.i, value.s)

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.

More Information and Examples
top
LastErrorHtml
Declare.s ckLastErrorHtml(obj.i) ; (read-only)

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
Declare.s ckLastErrorText(obj.i) ; (read-only)

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
Declare.s ckLastErrorXml(obj.i) ; (read-only)

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
Declare.i ckLastMethodSuccess(obj.i)
Declare setCkLastMethodSuccess(obj.i, value.i)

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
Length
Declare.i ckLength(obj.i) ; (read-only)

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

top
Trim
Declare.i ckTrim(obj.i)
Declare setCkTrim(obj.i, value.i)

If 1, whitespace, including carriage-returns and linefeeds, are automatically removed from the beginning and end of a string when added to the collection.

top
Unique
Declare.i ckUnique(obj.i)
Declare setCkUnique(obj.i, value.i)

If 1, 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 0.

top
VerboseLogging
Declare.i ckVerboseLogging(obj.i)
Declare setCkVerboseLogging(obj.i, value.i)

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.

top
Version
Declare.s ckVersion(obj.i) ; (read-only)

Version of the component/library, such as "9.5.0.94"

Methods

Append
Declare.i ckAppend(obj.i, str.s)

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

Returns 1 for success, 0 for failure.

top
AppendSerialized
Declare.i ckAppendSerialized(obj.i, encodedStr.s)

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

Returns 1 for success, 0 for failure.

top
Clear
Declare ckClear(obj.i)

Remove all strings from the internal collection.

top
Contains
Declare.i ckContains(obj.i, str.s)

Returns 1 if the string is present in the internal collection. The string comparisons are case sensitive.

top
Find
Declare.i ckFind(obj.i, findStr.s, startIndex.l)

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
Declare.i ckFindFirstMatch(obj.i, matchPattern.s, startIndex.l)

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
Declare.s ckGetString(obj.i, index.l)

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

Returns an empty string on failure. Use the LastMethodSuccess property to check for success.

top
GetStringLen
Declare.i ckGetStringLen(obj.i, index.l)

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

top
InsertAt
Declare ckInsertAt(obj.i, index.l, str.s)

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

top
LastString
Declare.s ckLastString(obj.i)

Returns the last string in the internal collection.

Returns an empty string on failure. Use the LastMethodSuccess property to check for success.

top
LoadFromFile
Declare.i ckLoadFromFile(obj.i, path.s)

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 1 for success, 0 for failure.

top
LoadFromFile2
Declare.i ckLoadFromFile2(obj.i, path.s, charset.s)

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

Returns 1 for success, 0 for failure.

top
LoadFromText
Declare ckLoadFromText(obj.i, str.s)

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
Declare.i ckLoadTaskResult(obj.i, task.i)
Introduced in version 9.5.0.52

Loads the string collection from a completed asynchronous task.

Returns 1 for success, 0 for failure.
