Class Description

---

This is a simple class that provides a string full of spaces. This may be used to avoid memory allocations/initializations.

Public Static Methods
static AString	get ()
static AString	get (int minSize)
static void	write (PrintStream os, int qty)
static void	write (Writer os, int qty)

Private Static Fields
static byte[]	spacesByte
static AString	theSpaces =new AString()

Member Function Documentation

get() [1/2]

static AString get ( )

static

---

Overloaded version of get(int) providing default parameter 128. It is recommended to generally use this method instead of the parameterized.

Returns

A const AString filled with spaces.

get() [2/2]

static AString get ( int  minSize )

static

---

Receives an AString full of spaces. The AString returned must not be altered.

Attention

Parameter minSize should be omitted and the size of the object returned accepted. Requesting a higher size, might result in slightly more efficiency. In multithreaded processes, changing the size must be performed during bootstrap, e.g. directly after invoking ALIB.init by calling this method with the appropriate size.

Parameters

minSize

The minimum number of spaces that should be available in the returned AString. Defaults to 128. See notes in method description!

Returns

A const AString filled with spaces.

write() [1/2]

static void write ( PrintStream  os, int  qty  )

static

---

Write the given number of spaces to a PrintStream.

Parameters

os	The output stream to write to
qty	The quantity of spaces to write

write() [2/2]

static void write ( Writer  os, int  qty  )

static

---

Write the given number of spaces to a Writer.

Parameters

os	The output stream to write to
qty	The quantity of spaces to write

Member Data Documentation

spacesByte

byte [] spacesByte

staticprivate

A fixed size byte array of spaces used in write(PrintStream, int). Unfortunately, Java does not provide a method in PrintStream to write a portion of a character array, therefore this is fixed (and redundant to field theSpaces).

theSpaces

AString theSpaces =new AString()

staticprivate

The internal string of spaces returned by get and used by write.
