Method Detail

setDefaultLangPrefix

public void setDefaultLangPrefix(java.lang.String langPrefix)

Define the default lang prefix to use when looking for a language property.

Parameters:

langPrefix - an ISO-639 language code (without any '.')

getLangProperty

public java.lang.String getLangProperty(java.lang.String name,
                               java.lang.Object... formArgs)

Resolve the given property name using the default language prefix.

Parameters:

name - the property name to resolve

formArgs - an array of parameters to use to for the format of property

Returns:

the resolved property

getExplicitLangProperty

public java.lang.String getExplicitLangProperty(LangProperty prop,
                                       java.lang.String language)

Resolve the given property name using the given language.

Parameters:

prop - the LangProperty instance corresponding to the property you want to resolve.

language - the ISO-639 code language to use to retrieve this property

Returns:

the resolved property

getExplicitLangProperty

public java.lang.String getExplicitLangProperty(java.lang.String name,
                                       java.lang.String language,
                                       java.lang.Object[] formArgs)

Resolve the given property name using the given language.

Example :

  String i18nStr = getExplicitLangProperty("ui.com.lbl.byte", "en", 6);
 

Parameters:

name - the property name to resolve

language - the language prefix used before the property name, usually an ISO-639 language code, if null, the default lang prefix is used.

formArgs - an array of parameters to use to for the format of property

Returns:

the resolved property

getExplicitLangProperty

public java.lang.String getExplicitLangProperty(java.lang.String name,
                                       java.lang.String language,
                                       java.util.Map<java.lang.String,java.lang.String> paramMap)

Resolve the given property name using the given language.

Example :

  Map paramMap = new HashMap();
  paramMap.put("firstName", "John");
  paramMap.put("lastName", "Doe");
  String i18nStr = getExplicitLangProperty("my.property", "en", paramMap);
 

with the given property:

 my.property: Hello {firstName} {lastName}
 

Parameters:

name - the property name to resolve

language - the language prefix used before the property name, usually an ISO-639 language code, if null, the default lang prefix is used.

paramMap - the map of parameters

Returns:

the resolved property

getLangStringArrayProperty

public java.lang.String[] getLangStringArrayProperty(java.lang.String name,
                                            java.lang.String[] defaultValue)

getProperties

public JProperties getProperties(java.lang.String prefix)

Returns a new property set of properties with key matching a given prefix.

Overrides:

getProperties in class JProperties

Parameters:

prefix - the prefix the properties must match to be added to the return LangProperties instance, if null, all properties are added.

Returns:

format

public java.lang.String format(java.lang.String format,
                      java.lang.Object[] objects)

This is a temporary implementation waiting for a more powerful Format.
The extensions of format compared to MessageFormat are
- the ability to use context properties {property} - the ability to use more than 10 parameters - '...' is not an escape sequence for the expension

Parameters:

format - the string containing the pattern to be replaced

objects - an array of objects to be formatted and substituted.

Returns:

the formated string

format

public java.lang.String format(java.lang.String format,

This is a temporary implementation waiting for a more powerful Format.
The extensions of format compared to MessageFormat are
- the ability to use context properties {property} - the ability to use more than 10 parameters - '...' is not an escape sequence for the expension

Parameters:

format - the string containing the pattern to be replaced

objects - an array of objects to be formatted and substituted.

language - the language in which the string is being renderrd, used for recursive property such as "Hello {some.other.property}! "

Returns:

the formated string

popLastFormatException

public java.lang.Exception popLastFormatException()
