public class FastStringWriter
extends java.io.PrintWriter

A subclass of java.io.PrintWriter with java.io.StringWriter code. All synchronized blocks have been removed. The advantage of having a FastStringWriter is to be able to use PrintWriter methods with a FastStringBuffer.

Constructor Detail

FastStringWriter

public FastStringWriter()

Create a new string writer, using the default initial string-buffer size.

FastStringWriter

public FastStringWriter(int initialSize)

Create a new string writer, using the specified initial string-buffer size.

Parameters:

initialSize - an int specifying the initial size of the buffer.

Method Detail

write

public void write(int c)

Write a single character.

Overrides:

write in class java.io.PrintWriter

write

public void write(char[] cbuf,
                  int off,
                  int len)

Write a portion of an array of characters.

Overrides:

write in class java.io.PrintWriter

Parameters:

cbuf - Array of characters

off - Offset from which to start writing characters

len - Number of characters to write

write

public void write(java.lang.String str)

Write a string.

Overrides:

write in class java.io.PrintWriter

write

public void write(java.lang.String str,
                  int off,
                  int len)

Write a portion of a string.

Overrides:

write in class java.io.PrintWriter

Parameters:

str - String to be written

off - Offset from which to start writing characters

len - Number of characters to write

toString

public java.lang.String toString()

Return the buffer's current value as a string.

Overrides:

toString in class java.lang.Object

getBuffer

public FastStringBuffer getBuffer()

Return the string buffer itself.

Returns:

StringBuffer holding the current buffer value.

flush

public void flush()

Flush the stream.

Specified by:

flush in interface java.io.Flushable

Overrides:

flush in class java.io.PrintWriter

close

public void close()

Closing a StringWriter has no effect. The methods in this class can be called after the stream has been closed without generating an IOException.

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

Overrides:

close in class java.io.PrintWriter

print

public void print(boolean b)

Print a boolean value. The string produced by String.valueOf(boolean) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

b - The boolean to be printed

print

public void print(char c)

Print a character. The character is translated into one or more bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

c - The char to be printed

print

public void print(int i)

Print an integer. The string produced by String.valueOf(int) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

i - The int to be printed

See Also:

Integer.toString(int)

print

public void print(long l)

Print a long integer. The string produced by String.valueOf(long) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

l - The long to be printed

See Also:

Long.toString(long)

print

public void print(float f)

Print a floating-point number. The string produced by String.valueOf(float) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

f - The float to be printed

See Also:

Float.toString(float)

print

public void print(double d)

Print a double-precision floating-point number. The string produced by String.valueOf(double) is translated into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

d - The double to be printed

See Also:

Double.toString(double)

print

public void print(char[] s)

Print an array of characters. The characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

s - The array of chars to be printed

Throws:

java.lang.NullPointerException - If s is null

print

public void print(java.lang.String s)

Print a string. If the argument is null then the string "null" is printed. Otherwise, the string's characters are converted into bytes according to the platform's default character encoding, and these bytes are written in exactly the manner of the write(int) method.

Overrides:

print in class java.io.PrintWriter

Parameters:

s - The String to be printed

print

public void print(java.lang.Object obj)

print in class java.io.PrintWriter

Parameters:

obj - The Object to be printed

See Also:

Object.toString()
