A class for concatenating strings efficiently.

Allows for the incremental building of a string using write*() methods. The strings are concatenated to a single string only when toString is called.

Implements

Properties

bool isEmpty
read-only
Returns whether the buffer is empty. This is a constant-time operation.
bool isNotEmpty
read-only
Returns whether the buffer is not empty. This is a constant-time operation.
int length
read-only
Returns the length of the content that has been accumulated so far. This is a constant-time operation.

Constructors

StringBuffer([Object content = ""])
Creates the string buffer with an initial content.

Methods

clear() → void
Clears the string buffer.
toString() → String
Returns the contents of buffer as a concatenated string.
write(Object obj) → void
Adds the contents of obj, converted to a string, to the buffer.
writeAll(Iterable objects, [String separator = ""]) → void
Iterates over the given objects and writes them in sequence.
writeCharCode(int charCode) → void
Adds the string representation of charCode to the buffer.
writeln([Object obj = ""]) → void
Converts obj to a String by invoking Object.toString and adds the result to this, followed by a newline.
