Package ch.qos.logback.core.rolling

Class RollingPolicyBase

java.lang.Object

ch.qos.logback.core.spi.ContextAwareBase

ch.qos.logback.core.rolling.RollingPolicyBase

All Implemented Interfaces:

RollingPolicy, ContextAware, LifeCycle

Direct Known Subclasses:

FixedWindowRollingPolicy, TimeBasedRollingPolicy

public abstract class RollingPolicyBase
extends ContextAwareBase
implements RollingPolicy

Implements methods common to most, it not all, rolling policies. Currently such methods are limited to a compression mode getter/setter.

Method Detail

determineCompressionMode

protected void determineCompressionMode()

Given the FileNamePattern string, this method determines the compression mode depending on last letters of the fileNamePatternStr. Patterns ending with .gz imply GZIP compression, endings with '.zip' imply ZIP compression, endings with .xz imply XZ compression. Otherwise and by default, there is no compression.

adjustCompressionModeAndFileNamePatternStrIfNecessary

protected void adjustCompressionModeAndFileNamePatternStrIfNecessary()

If compression mode is XZ but the XZ library is missing, then fallback to GZ compression.

setFileNamePattern

public void setFileNamePattern(String fnp)

getFileNamePattern

public String getFileNamePattern()

getCompressionMode

public CompressionMode getCompressionMode()

Description copied from interface: RollingPolicy

The compression mode for this policy.

Specified by:

getCompressionMode in interface RollingPolicy

Returns:

isStarted

public boolean isStarted()

Specified by:

isStarted in interface LifeCycle

start

public void start()

Specified by:

start in interface LifeCycle

stop

public void stop()

Specified by:

stop in interface LifeCycle

setParent

public void setParent(FileAppender<?> appender)

Description copied from interface: RollingPolicy

This method allows RollingPolicy implementations to be aware of their containing appender.

Specified by:

setParent in interface RollingPolicy

isParentPrudent

public boolean isParentPrudent()

getParentsRawFileProperty

public String getParentsRawFileProperty()
