- Returns:
- Encoding instance (never null)
- See Also:
- IEncodingFactory.getEncodingForCharset(java.nio.charset.Charset, Encoding)

- EncodingDefinition instance or nullif the character set name is not mapped
 
 - 
getEncodingForCharsetAliaspublic Encoding getEncodingForCharsetAlias(java.lang.String charsetAlias, Encoding fallbackEncoding) Gets anEncodingfor the specified Java character set name or alias. If there is no known encoding for this name, or the loaded EncodingDefinition is information-only, then the fallbackEncoding will be used.- Parameters:
- charsetAlias- The Java character set name or alias
- fallbackEncoding- The Encoding to use as fallback if no encoding is found (usually the connection encoding). If- null, the defaultEncoding for the JVM is used.

- Encoding instance (never null)
 
 - 
getEncodingForCharsetAliaspublic Encoding getEncodingForCharsetAlias(java.lang.String charsetAlias) Description copied from interface:IEncodingFactoryGets anEncodingfor the specified Java character set name or alias. If there is no known encoding for this name, or the loaded EncodingDefinition is information-only, then the defaultEncoding will be used.- Specified by:
- getEncodingForCharsetAliasin interface- IEncodingFactory
- Parameters:
- charsetAlias- The Java character set name or alias
- Returns:
- Encoding instance (never null)
 
 - 
getEncodingDefinitionpublic EncodingDefinition getEncodingDefinition(java.lang.String firebirdEncodingName, java.lang.String javaCharsetAlias) Description copied from interface:IEncodingFactoryGets or creates anEncodingDefinitionfor the supplied Firebird encoding and Java charset.When firebirdEncodingNameis not null andjavaCharsetAliasis null, then the encoding definition as returned byIEncodingFactory.getEncodingDefinitionByFirebirdName(String)is returned. For the reverse (firebirdEncodingNameis null andjavaCharsetAliasisn't), the encoding definition as returned byIEncodingFactory.getEncodingDefinitionByCharsetAlias(String)is returned.When both parameters are set, the result of IEncodingFactory.getEncodingDefinitionByFirebirdName(String)is returned if the character set matches, otherwise a newDefaultEncodingDefinitionis created based on its information, but with the specified character set. This can be useful for attempting to fix encoding issues in Firebird.If either of the parameters cannot be resolved, to an EncodingDefinition or Charset, or the EncodingDefinition is information-only - with the exception of Firebird encoding NONE - and no Java Charset is specified, then null is returned.- Specified by:
- getEncodingDefinitionin interface- IEncodingFactory
- Parameters:
- firebirdEncodingName- Name of the Firebird encoding, or null to defer decision to the java Charset alias
- javaCharsetAlias- Alias of the Java character set, or null to defer decision to the Firebird encoding
- Returns:
- An EncodingDefinition or null if both parameters are null, no encoding was found or if an exception occurred.
