Interface FormatBuffer
- AttributedFormatBuffer, StringFormatBuffer
This interface describes a modifiable buffer which contains attributed
characters. The implementation may or may not implements attributes. It
aims to greatly simplify and clarify the implementation of java.text
formatters. The buffer may be appended or have its tail cut. It may also
be completely cleant up.
void | append(char c)- This method appends a simple char to the buffer.
|
void | append(char c, Attribute attr)- This method appends a simple character to the buffer.
|
void | append(String s)- This method appends a simple string to the buffer.
|
void | append(String s, Attribute attr)- This method appends a simple string to the buffer.
|
void | append(String s, int[] ranges, List> attrs)- This method appends a simple string to the buffer.
|
void | clear()- This method resets completely the buffer.
|
void | cutTail(int length)- This method cuts the last characters of the buffer.
|
Attribute | getDefaultAttribute()- This method returns the current default attribute for the buffer.
|
int | length()- This method returns the number of character in the buffer.
|
void | setDefaultAttribute(Attribute attr)- This method changes the current default attribute for the next string
or character which will be appended to the buffer.

append
public void append(char c)
This method appends a simple char to the buffer. This part of
the buffer will be attributed using the default attribute.
c - The character to append to the buffer.
append
public void append(char c,
Attribute attr) This method appends a simple character to the buffer. This part of
the buffer will have the specified attribute (and only this one).
The default attribute may be changed after calling this method.
c - The character to append to the buffer.attr - Attribute to use for the character in the buffer.
append
public void append(String s)
This method appends a simple string to the buffer. This part of
the buffer will be attributed using the default attribute.
s - The string to append to the buffer.
append
public void append(String s,
Attribute attr) This method appends a simple string to the buffer. This part of
the buffer will have the specified attribute (and only this one).
The default attribute may be changed after calling this method.
s - The string to append to the buffer.attr - Attribute to use for the string in the buffer.
append
public void append(String s,
int[] ranges,
List> attrs) This method appends a simple string to the buffer. This part of
the buffer will be attributed using the specified ranges and attributes.
To have an example on how to specify ranges see
FormatCharacterIterator.
s - The string to append to the buffer.ranges - The ranges describing how the attributes should be applied
to the string.attrs - The attributes of the string in the buffer.
clear
public void clear()
This method resets completely the buffer.
cutTail
public void cutTail(int length)
This method cuts the last characters of the buffer. The number of
characters to cut is given by "length".
length - Number of characters to cut at the end of the buffer.
getDefaultAttribute
public Attribute getDefaultAttribute()
This method returns the current default attribute for the buffer.
- The default attribute for the buffer.
length
public int length()
This method returns the number of character in the buffer.
- The number of character in the buffer.
setDefaultAttribute
public void setDefaultAttribute(Attribute attr)
This method changes the current default attribute for the next string
or character which will be appended to the buffer.
attr - The attribute which will be used by default.
