public boolean contains(Charset cs)

Implements abstract java.nio.charset.Charset.contains.

Doc from java.nio.charset.Charset.contains.

Tells whether or not this charset contains the given charset.

A charset C is said to contain a charset D if, and only if, every character representable in D is also representable in C. If this relationship holds then it is guaranteed that every string that can be encoded in D can also be encoded in C without performing any replacements.

That C contains D does not imply that each character representable in C by a particular byte sequence is represented in D by the same byte sequence, although sometimes this is the case.

Every charset contains itself.

This method computes an approximation of the containment relation: If it returns true then the given charset is known to be contained by this charset; if it returns false, however, then it is not necessarily the case that the given charset is not contained in this charset.

isLegalReplacementback to summary
public boolean isLegalReplacement(byte[] repl)

Overrides java.nio.charset.CharsetEncoder.isLegalReplacement.

Doc from java.nio.charset.CharsetEncoder.isLegalReplacement.

Tells whether or not the given byte array is a legal replacement value for this encoder.

A replacement is legal if, and only if, it is a legal sequence of bytes in this encoder's charset; that is, it must be possible to decode the replacement into one or more sixteen-bit Unicode characters.

The default implementation of this method is not very efficient; it should generally be overridden to improve performance.
