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
- isEmpty → bool
-
read-only
Returns whether the buffer is empty. This is a constant-time operation.
- isNotEmpty → bool
-
read-only
Returns whether the buffer is not empty. This is a constant-time operation.
- length → int
-
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
objectsandwrites them in sequence. -
writeCharCode(
int charCode) → void -
Adds the string representation of
charCodeto the buffer. -
writeln(
[Object obj = ""]) → void -
Converts
objto a String by invokingObject.toStringand adds the result tothis, followed by a newline.
