public TransformerLog()

Method Detail

getUpperMaxEntries

protected int getUpperMaxEntries()

Overridden to specify the maximum value the maxEntries property may set. Generally quite a small number as values are stored in memory.

Returns 100 as this is currently held in memory.

getPropertyName

protected String getPropertyName()

Overridden to specify the property name that specifies the maximum number of entries.

addOrModify

protected void addOrModify(Deque<String> entries,
                           Object message)

Overridden in sub classes to add a new entry or modify and existing one

setTransformerDebug

public void setTransformerDebug(TransformerDebug transformerDebug)

setProperties

public void setProperties(Properties properties)

isDebugEnabled

public boolean isDebugEnabled()

Enabled if number of transformer debug entries is greater than 0 AND there is not a test function generating output.

Specified by:

isDebugEnabled in interface org.apache.commons.logging.Log

Overrides:

isDebugEnabled in class LogAdapter

debug

public void debug(Object message,
                  Throwable throwable)

Specified by:

debug in interface org.apache.commons.logging.Log

Overrides:

debug in class LogAdapter

Parameters:

message - to be appended to the log

throwable - ignored

remove

protected void remove(Deque<T> entries)

Removes an entry. By default removes the first (oldest) entry by may be overridden.

getEntries

public String[] getEntries(int n)

Returns the log entries.

Parameters:
