protected XmlConfigurator(String stackName)

Method Detail

getInstance

public static XmlConfigurator getInstance(URL url)

getInstance

public static XmlConfigurator getInstance(InputStream stream)

getInstance

public static XmlConfigurator getInstance(Element el)

getInstanceOldFormat

public static XmlConfigurator getInstanceOldFormat(URL url)

getInstanceOldFormat

public static XmlConfigurator getInstanceOldFormat(InputStream stream)

getProtocolStack

public ProtocolData[] getProtocolStack()

getProtocolStackString

public String getProtocolStackString(boolean convert)

Parameters: convert If false: print old plain output, else print new XML format

Returns: String with protocol stack in specified format

parse

protected static XmlConfigurator parse(InputStream stream)

parse

protected static XmlConfigurator parse(Element root_element)

CAUTION: crappy code ahead ! I (bela) am not an XML expert, so the code below is pretty amateurish... But it seems to work, and it is executed only on startup, so no perf loss on the critical path. If somebody wants to improve this, please be my guest.

parseOldFormat

protected static XmlConfigurator parseOldFormat(InputStream stream)

parseProtocolData

protected static ProtocolData parseProtocolData(Node protocol)

parseProtocolParameters

protected static ProtocolParameter[] parseProtocolParameters(Element protparams)

there should be 4 Element Nodes if we are not overriding 1. protocol-name 2. description 3. class-name 4. protocol-params If we are overriding we should have 1. protocol-name 2. protocol-params

replace

public static String replace(String input, String expr, String replacement)
