CkStringBuilder Java Reference Documentation

CkStringBuilder

Current Version: 9.5.0.75

A simple class for building strings. (Represents a mutable string of characters.)

Note: This class was introduced in Chilkat v9.5.0.58.

Object Creation

CkStringBuilder obj = new CkStringBuilder();

Properties

IntValue
int get_IntValue();
void put_IntValue(int newVal);
Introduced in version 9.5.0.58

Returns the content of the string converted to an integer.

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

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();
Introduced in version 9.5.0.58

The number of characters of the string contained within this instance.

Methods

Append
boolean Append(String value);
Introduced in version 9.5.0.58

Appends a copy of the specified string to this instance.

Returns true for success, false for failure.

top
AppendBd
boolean AppendBd(CkBinData binData, String charset, int offset, int numBytes);
Introduced in version 9.5.0.64

Appends the contents of binData. The charset specifies the character encoding of the bytes contained in binData. The charset can be any of the supported encodings listed at Chilkat Supported Character Encodings. To append the entire contents of binData, set offset and numBytes equal to zero. To append a range of binData, set the offset and numBytes to specify the range.

Returns true for success, false for failure.

top
AppendEncoded
boolean AppendEncoded(CkByteData binaryData, String encoding);
Introduced in version 9.5.0.58

Appends binary data using the encoding specified by encoding, such as "base64", "hex", etc.

Returns true for success, false for failure.

top
AppendInt
boolean AppendInt(int value);
Introduced in version 9.5.0.58

Appends the string representation of a specified 32-bit signed integer to this instance.

Returns true for success, false for failure.

top
AppendInt64
boolean AppendInt64(long long value);
Introduced in version 9.5.0.58

Appends the string representation of a specified 64-bit signed integer to this instance.

Returns true for success, false for failure.

top
AppendLine
boolean AppendLine(String value, boolean crlf);
Introduced in version 9.5.0.65

Appends the value followed by a CRLF or LF to the end of the curent StringBuilder object. If crlf is true, then a CRLF line ending is used. Otherwise a LF line ending is used.

Returns true for success, false for failure.

top
AppendSb
boolean AppendSb(CkStringBuilder sb);
Introduced in version 9.5.0.62

Appends the contents of another StringBuilder to this instance.

Returns true for success, false for failure.

top
Clear
void Clear();
Introduced in version 9.5.0.58

Removes all characters from the current StringBuilder instance.

top
Contains
boolean Contains(String str, boolean caseSensitive);
Introduced in version 9.5.0.58

Returns true if the str is contained within this object. For case sensitive matching, set caseSensitive equal to true. For case-insensitive, set caseSensitive equal to false.

top
ContainsWord
boolean ContainsWord(String word, boolean caseSensitive);
Introduced in version 9.5.0.69

Returns true if the word is contained within this object, but only if it is a whole word. This method is limited to finding whole words in strings that only contains characters in the Latin1 charset (i.e. iso-8859-1 or Windows-1252). A whole word can only contain alphanumeric chars where the alpha chars are restricted to those of the Latin1 alpha chars. (The underscore character is also considered part of a word.)

For case sensitive matching, set caseSensitive equal to true. For case-insensitive, set caseSensitive equal to false.

top
ContentsEqual
boolean ContentsEqual(String str, boolean caseSensitive);
Introduced in version 9.5.0.62

Returns true if the contents of this object equals the str. Returns false if unequal. For case insensitive equality, set caseSensitive equal to false.

top
ContentsEqualSb
boolean ContentsEqualSb(CkStringBuilder sb, boolean caseSensitive);
Introduced in version 9.5.0.62

Returns true if the contents of this object equals the sb. Returns false if unequal. For case insensitive equality, set caseSensitive equal to false.

top
Decode
boolean Decode(String encoding, String charset);
Introduced in version 9.5.0.62

Decodes and replaces the contents with the decoded string. The encoding can be set to any of the following strings: "base64", "hex", "quoted-printable" (or "qp"), "url", "base32", "Q", "B", "url_rc1738", "url_rfc2396", "url_rfc3986", "url_oauth", "uu", "modBase64", or "html" (for HTML entity encoding). The full up-to-date list of supported binary encodings is available at the link entitled "Supported Binary Encodings" below.

Note: This method can only be called if the encoded content decodes to a string. The charset indicates the charset to be used in intepreting the decoded bytes. For example, the charset can be "utf-8", "utf-16", "iso-8859-1", "shift_JIS", etc.

Returns true for success, false for failure.

top
