 com.ibm.icu.text.ReplaceableString
| ReplaceableString | | public class ReplaceableString implements Replaceable(Code) | | ReplaceableString is an adapter class that implements the
Replaceable API around an ordinary StringBuffer.
Note: This class does not support attributes and is not
intended for general use. Most clients will need to implement
Replaceable in their text representation class.

| Method Summary | |
| public int | char32At(int offset)
Return the 32-bit code point at the given 16-bit offset into
the text. | | public char | charAt(int offset)
Return the character at the given position in this object. | | public void | copy(int start, int limit, int dest)
Copy a substring of this object, retaining attribute (out-of-band)
information. | | public void | getChars(int srcStart, int srcLimit, char dst, int dstStart)
Copies characters from this object into the destination
character array. | | public boolean | hasMetaData()
| | public int | length()
Return the number of characters contained in this object. | | public void | replace(int start, int limit, String text)
Replace zero or more characters with new characters. | | public void | replace(int start, int limit, char[] chars, int charsStart, int charsLen)
Replace a substring of this object with the given text. | | public String | substring(int start, int limit)
Return a substring of the given string. | | public String | toString()
Return the contents of this object as a String. |
| ReplaceableString | | public ReplaceableString(String str)(Code) | | Construct a new object with the given initial contents.
Parameters:
str - initial contents |
| ReplaceableString | | public ReplaceableString(StringBuffer buf)(Code) | | Construct a new object using buf for internal
storage. The contents of buf at the time of
construction are used as the initial contents. Note!
Modifications to buf will modify this object, and
vice versa.
Parameters:
buf - object to be used as internal storage |
| ReplaceableString | | public ReplaceableString()(Code) | | Construct a new empty object.
|
| char32At | | public int char32At(int offset)(Code) | | Return the 32-bit code point at the given 16-bit offset into
the text. This assumes the text is stored as 16-bit code units
with surrogate pairs intermixed. If the offset of a leading or
trailing code unit of a surrogate pair is given, return the
code point of the surrogate pair.
Parameters:
offset - an integer between 0 and length()-1inclusive 32-bit code point of text at given offset |
| charAt | | public char charAt(int offset)(Code) | | Return the character at the given position in this object.
Replaceable API.
Parameters:
offset - offset into the contents, from 0 tolength() - 1 |
| copy | | public void copy(int start, int limit, int dest)(Code) | | Copy a substring of this object, retaining attribute (out-of-band)
information. This method is used to duplicate or reorder substrings.
The destination index must not overlap the source range.
Parameters:
start - the beginning index, inclusive; 0 <= start <=limit.
Parameters:
limit - the ending index, exclusive; start <= limit <=length().
Parameters:
dest - the destination index. The characters fromstart..limit-1 will be copied to dest.Implementations of this method may assume that dest <= start ||dest >= limit. |
| getChars | | public void getChars(int srcStart, int srcLimit, char dst, int dstStart)(Code) | | Copies characters from this object into the destination
character array. The first character to be copied is at index
srcStart; the last character to be copied is at
index srcLimit-1 (thus the total number of
characters to be copied is srcLimit-srcStart). The
characters are copied into the subarray of dst
starting at index dstStart and ending at index
dstStart + (srcLimit-srcStart) - 1.
Parameters:
srcStart - the beginning index to copy, inclusive; 0<= start <= limit.
Parameters:
srcLimit - the ending index to copy, exclusive;start <= limit <= length().
Parameters:
dst - the destination array.
Parameters:
dstStart - the start offset in the destination array. |
| hasMetaData | | public boolean hasMetaData()(Code) | | Implements Replaceable
|
| length | | public int length()(Code) | | Return the number of characters contained in this object.
Replaceable API.
|
| replace | | public void replace(int start, int limit, String text)(Code) | | Replace zero or more characters with new characters.
Replaceable API.
Parameters:
start - the beginning index, inclusive; 0 <= start<= limit.
Parameters:
limit - the ending index, exclusive; start <= limit<= length().
Parameters:
text - new text to replace characters start tolimit - 1 |
| replace | | public void replace(int start, int limit, char[] chars, int charsStart, int charsLen)(Code) | | Replace a substring of this object with the given text.
Parameters:
start - the beginning index, inclusive; 0 <= start<= limit.
Parameters:
limit - the ending index, exclusive; start <= limit<= length().
Parameters:
chars - the text to replace characters startto limit - 1
Parameters:
charsStart - the beginning index into chars,inclusive; 0 <= start <= limit.
Parameters:
charsLen - the number of characters of chars. |
| substring | | public String substring(int start, int limit)(Code) | | Return a substring of the given string.
|
| toString | | public String toString()(Code) | | Return the contents of this object as a String.
string contents of this object |
