contains	back to summary
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. Parameters cs:Charset The given charset Returns:boolean `true` if the given charset is contained in this charset Annotations @Override

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.

Parameters

cs:Charset: The given charset

Returns:boolean

true if the given charset is contained in this charset
