Constructor Details

XmlConfiguration

public XmlConfiguration(LoggerContext loggerContext,
 ConfigurationSource source,
 int monitorIntervalSeconds)

Method Details

addAppenderIfAbsent

public void addAppenderIfAbsent(Appender appender)

doConfigure

public void doConfigure()
                 throws FactoryConfigurationError

Configures log4j by reading in a log4j.dtd compliant XML configuration file.

Overrides:

doConfigure in class AbstractConfiguration

Throws:

FactoryConfigurationError

reconfigure

public Configuration reconfigure()

Specified by:

reconfigure in interface Reconfigurable

Overrides:

reconfigure in class Log4j1Configuration

subst

public String subst(String value,
 Properties props)

Substitutes property value for any references in expression.

Parameters:

value - value from configuration file, may contain literal text, property references or both

props - properties.

Returns:

evaluated expression, may still contain expressions if unable to expand.

setParameter

public void setParameter(Element elem,
 PropertySetter propSetter,
 Properties props)

Sets a parameter based from configuration file content.

Parameters:

elem - param element, may not be null.

propSetter - property setter, may not be null.

props - properties

Since:

1.2.15

parseElement

public Object parseElement(Element element,
 Properties props,
 Class expectedClass)
                    throws Exception

Creates an object and processes any nested param elements but does not call activateOptions. If the class also supports UnrecognizedElementParser, the parseUnrecognizedElement method will be call for any child elements other than param.

Parameters:

element - element, may not be null.

props - properties

expectedClass - interface or class expected to be implemented by created class

Returns:

created class or null.

Throws:

Exception - thrown if the contain object should be abandoned.
