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.
Properties
-
int
length
-
read-only
Returns the length of the content that has been accumulated so far.
This is a constant-time operation.
-
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.
Constructors
-
StringBuffer([Object content = ""])
-
Creates the string buffer with an initial content.
Methods
-
write(Object obj)
→
void
-
Adds the contents of obj, converted to a string, to the buffer.
-
writeCharCode(int charCode)
→
void
-
Adds the string representation of charCode to the buffer.
-
writeAll(Iterable objects, [String separator = ""])
→
void
-
Iterates over the given [objects] and [write]s them in sequence.
-
writeln([Object obj = ""])
→
void
-
Converts [obj] to a String by invoking [Object.toString] and
adds the result to this, followed by a newline.
-
clear()
→
void
-
Clears the string buffer.
-
toString()
→
String
-
Returns the contents of buffer as a concatenated string.
