public abstract class CharsetEncoderICU
extends CharsetEncoder

An abstract class that provides framework methods of decoding operations for concrete subclasses. In the future this class will contain API that will implement converter semantics of ICU4C.

Method Summary

Modifier and Type	Method	Description
boolean	canEncode(int[] codepoint)
boolean	isFallbackUsed()	Is this Encoder allowed to use fallbacks? A fallback mapping is a mapping that will convert a Unicode codepoint sequence to a byte sequence, but the encoded byte sequence will round trip convert to a different Unicode codepoint sequence.
boolean	isLegalReplacement(byte[] repl)	Overrides super class method
void	setFallbackUsed(boolean usesFallback)	Sets whether this Encoder can use fallbacks?
final void	setFromUContext(Object newContext)	Sets fromUContext used in callbacks.

Method Details

isFallbackUsed

public boolean isFallbackUsed()

Is this Encoder allowed to use fallbacks? A fallback mapping is a mapping that will convert a Unicode codepoint sequence to a byte sequence, but the encoded byte sequence will round trip convert to a different Unicode codepoint sequence.

Returns:

true if the converter uses fallback, false otherwise.

setFallbackUsed

public void setFallbackUsed(boolean usesFallback)

Sets whether this Encoder can use fallbacks?

Parameters:

usesFallback - true if the user wants the converter to take advantage of the fallback mapping, false otherwise.

setFromUContext

public final void setFromUContext(Object newContext)

Sets fromUContext used in callbacks.

Parameters:

newContext - Object

Throws:

IllegalArgumentException

canEncode

public boolean canEncode(int[] codepoint)

Parameters:

codepoint - Unicode code point as int array

Returns:

true if the input sequence can be converted

isLegalReplacement

public boolean isLegalReplacement(byte[] repl)

Overrides super class method

Overrides:
