CharsetMatch (ICU4J 50)

java.lang.Object
- com.ibm.icu.text.CharsetMatch

All Implemented Interfaces:

java.lang.Comparable<CharsetMatch>
```
public class CharsetMatch
extends java.lang.Object
implements java.lang.Comparable<CharsetMatch>
```
This class represents a charset that has been identified by a CharsetDetector as a possible encoding for a set of input data. From an instance of this class, you can ask for a confidence level in the charset identification, or for Java Reader or String to access the original byte data in Unicode form.
Instances of this class are created only by CharsetDetectors.
Note: this class has a natural ordering that is inconsistent with equals. The natural ordering is based on the match confidence value.

Status:
Stable ICU 3.4.

Method Summary

Methods
Modifier and Type	Method and Description
`int`	`compareTo(CharsetMatch other)` Compare to other CharsetMatch objects.
`int`	`getConfidence()` Get an indication of the confidence in the charset detected.
`java.lang.String`	`getLanguage()` Get the ISO code for the language of the detected charset.
`java.lang.String`	`getName()` Get the name of the detected charset.
`java.io.Reader`	`getReader()` Create a java.io.Reader for reading the Unicode character data corresponding to the original byte data supplied to the Charset detect operation.
`java.lang.String`	`getString()` Create a Java String from Unicode character data corresponding to the original byte data supplied to the Charset detect operation.
`java.lang.String`	`getString(int maxLength)` Create a Java String from Unicode character data corresponding to the original byte data supplied to the Charset detect operation.

- Method Detail
  - getReader
```
public java.io.Reader getReader()
```
    Create a java.io.Reader for reading the Unicode character data corresponding to the original byte data supplied to the Charset detect operation.
    CAUTION: if the source of the byte data was an InputStream, a Reader can be created for only one matching char set using this method. If more than one charset needs to be tried, the caller will need to reset the InputStream and create InputStreamReaders itself, based on the charset name.
    
    Returns:
    the Reader for the Unicode character data.
    Status:
    Stable ICU 3.4.
  - getString
```
public java.lang.String getString()
                           throws java.io.IOException
```
    Create a Java String from Unicode character data corresponding to the original byte data supplied to the Charset detect operation.
    
    Returns:
    a String created from the converted input data.
    
    Throws:
    
    java.io.IOException
    Status:
    Stable ICU 3.4.
  - getString
```
public java.lang.String getString(int maxLength)
                           throws java.io.IOException
```
    Create a Java String from Unicode character data corresponding to the original byte data supplied to the Charset detect operation. The length of the returned string is limited to the specified size; the string will be trunctated to this length if necessary. A limit value of zero or less is ignored, and treated as no limit.
    
    Parameters:
    maxLength - The maximium length of the String to be created when the source of the data is an input stream, or -1 for unlimited length.
    
    Returns:
    a String created from the converted input data.
    
    Throws:
    
    java.io.IOException
    Status:
    Stable ICU 3.4.
  - getConfidence
```
public int getConfidence()
```
    Get an indication of the confidence in the charset detected. Confidence values range from 0-100, with larger numbers indicating a better match of the input data to the characteristics of the charset.
    
    Returns:
    the confidence in the charset match
    Status:
    Stable ICU 3.4.
  - getName
```
public java.lang.String getName()
```
    Get the name of the detected charset. The name will be one that can be used with other APIs on the platform that accept charset names. It is the "Canonical name" as defined by the class java.nio.charset.Charset; for charsets that are registered with the IANA charset registry, this is the MIME-preferred registerd name.
    
    Returns:
    The name of the charset.

    Charset, InputStreamReader
    Status:
    Stable ICU 3.4.
  - getLanguage
```
public java.lang.String getLanguage()
```
    Get the ISO code for the language of the detected charset.
    
    Returns:
    The ISO code for the language or null if the language cannot be determined.
    Status:
    Stable ICU 3.4.
  - compareTo
```
public int compareTo(CharsetMatch other)
```
    Compare to other CharsetMatch objects. Comparison is based on the match confidence value, which allows CharsetDetector.detectAll() to order its results.
    
    Specified by:
    
    compareTo in interface java.lang.Comparable<CharsetMatch>
    
    Parameters:
    other - the CharsetMatch object to compare against.
    
    Returns:
    a negative integer, zero, or a positive integer as the confidence level of this CharsetMatch is less than, equal to, or greater than that of the argument.
    
    Throws:
    
    java.lang.ClassCastException - if the argument is not a CharsetMatch.
    Status:
    Stable ICU 4.4.
