Constructor Detail

New

PROCEDURE New(str: STRING): StringBuffer

NewLatin1

PROCEDURE NewLatin1(str: ARRAY OF CHAR): StringBuffer

NewLatin1Region

PROCEDURE NewLatin1Region(str: ARRAY OF CHAR; 
                          start: LONGINT; 
                          end: LONGINT): StringBuffer
Method Detail

Append

PROCEDURE (b: StringBuffer) Append(obj: Object)

AppendBool

PROCEDURE (b: StringBuffer) AppendBool(val: BOOLEAN)

Append the string representation of a BOOLEAN val to the current string.


AppendChar

PROCEDURE (b: StringBuffer) AppendChar(ch: UCS4CHAR)

AppendInt

PROCEDURE (b: StringBuffer) AppendInt(val: LONGINT)

Append the string representation of LONGINT val to the current string


AppendLatin1

PROCEDURE (b: StringBuffer) AppendLatin1(data: ARRAY OF CHAR)

AppendLatin1Char

PROCEDURE (b: StringBuffer) AppendLatin1Char(ch: CHAR)

AppendLatin1Region

PROCEDURE (b: StringBuffer) AppendLatin1Region(data: ARRAY OF CHAR; 
                             start: LONGINT; 
                             end: LONGINT)

AppendLn

PROCEDURE (b: StringBuffer) AppendLn()

Append a newline character Ascii.lf to the buffer.


AppendReal

PROCEDURE (b: StringBuffer) AppendReal(val: REAL)

Append the string representation of REAL val to the current string


AppendSet

PROCEDURE (b: StringBuffer) AppendSet(val: SET)

Append the string representation of a SET val to the currrent string.


AppendUTF16Region

PROCEDURE (b: StringBuffer) AppendUTF16Region(data: ARRAY OF LONGCHAR; 
                            start: LONGINT; 
                            end: LONGINT)

CharAt

PROCEDURE (b: StringBuffer) CharAt(index: LONGINT): UCS4CHAR

CharsLatin1

PROCEDURE (b: StringBuffer) CharsLatin1(): CharsLatin1

Return a reference to the character data of the string buffer. It holds valid character data in the index range `0' to `b.length-1'. The element at index `b.length' is `0X'. Please note that the string buffer may also contain `0X' itself.

If wide characters have been added to b, then no CharsLatin1 representation is available and result is NIL.

Important: The reference only remains valid until the first operation that modifies the buffer. After such an operation, it may or may not reflect the current buffer contents.


CharsUTF16

PROCEDURE (b: StringBuffer) CharsUTF16(): CharsUTF16

Return a reference to the character data of the string buffer. It holds valid character data in the index range `0' to `b.length-1'. The element at index `b.length' is `0X'. Please note that the string buffer may also contain `0X' itself.

If no wide characters have been added to b, then the internal representation is still CharsLatin1, and result is NIL.

Important: The reference only remains valid until the first operation that modifies the buffer. After such an operation, it may or may not reflect the current buffer contents.


Clear

PROCEDURE (b: StringBuffer) Clear()

ConvertTo16

PROCEDURE (b: StringBuffer) [ConvertTo16]()

Delete

PROCEDURE (b: StringBuffer) Delete(start: LONGINT; 
                 end: LONGINT)

EnsureCapacity

PROCEDURE (b: StringBuffer) [EnsureCapacity](cap: LONGINT)

INIT

PROCEDURE (b: StringBuffer) INIT(initialCapacity: LONGINT)

Insert

PROCEDURE (b: StringBuffer) Insert(obj: Object; 
                 at: LONGINT)

ToString

PROCEDURE (b: StringBuffer) ToString(): STRING

Returns a string representation of the object. Typically, the string is some form of "natural" representation of the value. For complex objects, it should describe the type and essential attributes of the object. The exact format of the returned value is intentionally left vague.
