Field Summary

private EncodingInfo.InEncoding	m_after The object, of the same type as this one, that handles unicode values in a range after the range explictly handled by this object, and to which this object may delegate.
private boolean[]	m_alreadyKnown A flag to record if we already know the answer for the given unicode value.
private EncodingInfo.InEncoding	m_before The object, of the same type as this one, that handles unicode values in a range before the range explictly handled by this object, and to which this object may delegate.
private java.lang.String	m_encoding The encoding.
private int	m_explFirst m_explFirst through m_explLast is the range of unicode value that this object handles explicitly and does not delegate to a similar object.
private int	m_explLast
private int	m_first m_first through m_last is the range of unicode values that this object will return an answer on.
private boolean[]	m_isInEncoding A table holding the answer on whether the given unicode value is in the encoding.
private int	m_last
private static int	RANGE The number of unicode values explicitly handled by a single EncodingInfo object.

Constructor Summary

private	EncodingInfo.EncodingImpl()
private	EncodingInfo.EncodingImpl(java.lang.String encoding, int first, int last, int codePoint)

Method Summary

boolean	isInEncoding(char ch1) Returns true if the char is in the encoding
boolean	isInEncoding(char high, char low) Returns true if the high/low surrogate pair forms a character that is in the encoding.

Field Detail

m_encoding

private final java.lang.String m_encoding

The encoding.

m_first

private final int m_first

m_first through m_last is the range of unicode values that this object will return an answer on. It may delegate to a similar object with a different range

m_explFirst

private final int m_explFirst

m_explFirst through m_explLast is the range of unicode value that this object handles explicitly and does not delegate to a similar object.

m_explLast

private final int m_explLast

m_last

private final int m_last

m_before

private EncodingInfo.InEncoding m_before

The object, of the same type as this one, that handles unicode values in a range before the range explictly handled by this object, and to which this object may delegate.

m_after

private EncodingInfo.InEncoding m_after

The object, of the same type as this one, that handles unicode values in a range after the range explictly handled by this object, and to which this object may delegate.

RANGE

private static final int RANGE

The number of unicode values explicitly handled by a single EncodingInfo object. This value is tuneable, but is set to 128 because that covers the entire low range of ASCII type chars within a single object.

Constant Field Values

m_alreadyKnown

private final boolean[] m_alreadyKnown

A flag to record if we already know the answer for the given unicode value.

m_isInEncoding

private final boolean[] m_isInEncoding

A table holding the answer on whether the given unicode value is in the encoding.
