Method Detail

setFilter

public void setFilter(java.lang.String... names)

Sets a filter so that only sub-elements of a specific element are captured

For example, if the desired elements were inside

<x><y>

and the input were

<x><y><a/><b/><c/></x></y>

the filter would pass

<a/><b/><c/>

The call in this example would be: setFilter("x", "y").

Parameters:

names - names of elements leading to the target elements; use null to disable filtering (capture all events)

setAttributeWatch

public void setAttributeWatch(java.lang.String elemName)

Sets a "watch" for an element's attributes, which can be retrieved with getAttributeWatchValues(). During the parsing of the SAX events, the START-elements are searched for the target element name. If found, the element's attributes are stored. This checks all START- elements, regardless of filtering.

Parameters:

elemName - name of the element

getAttributeWatchValues

public java.util.Map<java.lang.String,java.lang.String> getAttributeWatchValues()

Gets the attributes set by setAttributeWatch(String)

Returns:

attributes (name to value) of the watched element; if the element was not encountered, this returns null

recordEvents

public java.util.List<ch.qos.logback.core.joran.event.SaxEvent> recordEvents(org.xml.sax.InputSource src)
                                                                      throws ch.qos.logback.core.joran.spi.JoranException

Parses SAX events from a compressed Android XML resource

Overrides:

recordEvents in class ch.qos.logback.core.joran.event.SaxEventRecorder

Parameters:

src - input source pointing to a compressed Android XML resource

Throws:

ch.qos.logback.core.joran.spi.JoranException
