UnicodeReplacer defines a protocol for objects that
replace a range of characters in a Replaceable string with output
text. The replacement is done via the Replaceable API so as to
preserve out-of-band data.
| Modifier and Type | Method and Description |
|---|---|
| public void | addReplacementSetTo(UnicodeSet
the set into which to union the output characters toUnionTo)Union the set of all characters that may output by this object into the given set. |
| public int | Returns: the number of 16-bit code units in the text replacing the characters at offsets start..(limit-1) in textthe text to be matched text, int inclusive start index of text to be replaced start, int exclusive end index of text to be replaced;
must be greater than or equal to start limit, int[] output parameter for the cursor position.
Not all replacer objects will update this, but in a complete
tree of replacer objects, representing the entire output side
of a transliteration rule, at least one must update it. cursor)Replace characters in 'text' from 'start' to 'limit' with the output text of this object. |
| public String | toReplacerPattern(boolean
if true then convert unprintable
character to their hex escape representations, \\uxxxx or
\\Uxxxxxxxx. Unprintable characters are defined by
Utility.isUnprintable(). escapeUnprintable)Returns a string representation of this replacer. |

| replace | back to summary |
|---|---|
| public int replace(Replaceable text, int start, int limit, int[] cursor) Replace characters in 'text' from 'start' to 'limit' with the output text of this object. Update the 'cursor' parameter to give the cursor position and return the length of the replacement text.

| toReplacerPattern | back to summary |
|---|---|
| public String toReplacerPattern(boolean escapeUnprintable) Returns a string representation of this replacer. If the result of calling this function is passed to the appropriate parser, typically TransliteratorParser, it will produce another replacer that is equal to this one.
