Class UScriptRun

java.lang.Object

com.ibm.icu.lang.UScriptRun

Deprecated.

This API is ICU internal only.

@Deprecated
public final class UScriptRun
extends Object

UScriptRun is used to find runs of characters in the same script, as defined in the UScript class. It implements a simple iterator over an array of characters. The iterator will assign COMMON and INHERITED characters to the same script as the preceeding characters. If the COMMON and INHERITED characters are first, they will be assigned to the same script as the following characters. The iterator will try to match paired punctuation. If it sees an opening punctuation character, it will remember the script that was assigned to that character, and assign the same script to the matching closing punctuation. No attempt is made to combine related scripts into a single run. In particular, Hiragana, Katakana, and Han characters will appear in separate runs. Here is an example of how to iterate over script runs:

 void printScriptRuns(char[] text)
 {
     UScriptRun scriptRun = new UScriptRun(text);

     while (scriptRun.next()) {
         int start  = scriptRun.getScriptStart();
         int limit  = scriptRun.getScriptLimit();
         int script = scriptRun.getScriptCode();

         System.out.println("Script \"" + UScript.getName(script) + "\" from " +
                            start + " to " + limit + ".");
     }
  }

Constructor Detail

UScriptRun

@Deprecated
public UScriptRun()

Deprecated. This API is ICU internal only.

Construct an empty UScriptRun object. The next() method will return false the first time it is called.

UScriptRun

@Deprecated
public UScriptRun(String text)

Deprecated. This API is ICU internal only.

Construct a UScriptRun object which iterates over the characters in the given string.

Parameters:

text - the string of characters over which to iterate.

UScriptRun

@Deprecated
public UScriptRun(String text,
                              int start,
                              int count)

Deprecated. This API is ICU internal only.

Construct a UScriptRun object which iterates over a subrange of the characetrs in the given string.

Parameters:

text - the string of characters over which to iterate.

start - the index of the first character over which to iterate

count - the number of characters over which to iterate

UScriptRun

@Deprecated
public UScriptRun(char[] chars)

Deprecated. This API is ICU internal only.

Construct a UScriptRun object which iterates over the given characetrs.

Parameters:

chars - the array of characters over which to iterate.

UScriptRun

@Deprecated
public UScriptRun(char[] chars,
                              int start,
                              int count)

Deprecated. This API is ICU internal only.

Construct a UScriptRun object which iterates over a subrange of the given characetrs.

Parameters:

chars - the array of characters over which to iterate.

start - the index of the first character over which to iterate

count - the number of characters over which to iterate

Method Detail

reset

@Deprecated
public final void reset()

Deprecated. This API is ICU internal only.

Reset the iterator to the start of the text.

reset

@Deprecated
public final void reset(int start,
                                    int count)
                             throws IllegalArgumentException

Deprecated. This API is ICU internal only.

Reset the iterator to iterate over the given range of the text. Throws IllegalArgumentException if the range is outside of the bounds of the character array.

Parameters:

start - the index of the new first character over which to iterate

count - the new number of characters over which to iterate.

Throws:

IllegalArgumentException - If invalid arguments are passed.

reset

@Deprecated
public final void reset(char[] chars,
                                    int start,

start - the index of the first character over which to iterate.

count - the number of characters over which to iterate.

reset

@Deprecated
public final void reset(char[] chars)

Deprecated. This API is ICU internal only.

Deprecated. This API is ICU internal only.

Reset the iterator to iterate over count characters in text starting at start. This allows clients to reuse an iterator.

start - the index of the first character over which to iterate.

count - the nuber of characters over which to iterate.

reset

@Deprecated
public final void reset(String str)

Deprecated. This API is ICU internal only.

the index of the first character in the current script run.

getScriptLimit

@Deprecated
public final int getScriptLimit()

Deprecated. This API is ICU internal only.
