Class CharsetEncoding.Any

java.lang.Object

org.postgresql.pljava.model.CharsetEncoding.Any

All Implemented Interfaces:

CharsetEncoding

Enclosing interface:

CharsetEncoding

public static class CharsetEncoding.Any
extends Object
implements CharsetEncoding

A distinguished CharsetEncoding representing uses such as -1 in the collencoding column of pg_collation, indicating the collation is usable with any encoding.

This returns -1 from ordinal() and null or false from the other non-default methods according to their types. The only instance of this class is CharsetEncoding.ANY.

Method Details

ordinal

public int ordinal()

Description copied from interface: CharsetEncoding

Returns the PostgreSQL encoding number (as used in the encoding columns of some system catalogs) for this encoding.

Specified by:

ordinal in interface CharsetEncoding

name

public String name()

Description copied from interface: CharsetEncoding

Returns the PostgreSQL name for this encoding.

The PostgreSQL encoding names have a long history and may not match cleanly with more standardized names in modern libraries.

Specified by:

name in interface CharsetEncoding

icuName

public String icuName()

Description copied from interface: CharsetEncoding

Returns the name identifying this encoding in ICU (international components for Unicode), or null if its implementation in PostgreSQL does not define one.

When present, the ICU name can be a better choice for matching encodings in other libraries.

Specified by:

icuName in interface CharsetEncoding

usableOnServer

public boolean usableOnServer()

Description copied from interface: CharsetEncoding

Indicates whether this encoding is usable as a server encoding.

Specified by:

usableOnServer in interface CharsetEncoding

charset

public Charset charset()

Description copied from interface: CharsetEncoding

Returns the corresponding Java Charset, or null if none can be identified.

Specified by:

charset in interface CharsetEncoding

toString

public String toString()

Overrides:

toString in class Object
