Method Detail

makeStylesheet

protected String makeStylesheet(String xpathExpression,
                                String resultVal)

configure

public void configure()
               throws ConfigurationException

Description copied from class: AbstractPipe

configure() is called after the Pipeline is registered at the Adapter. Purpose of this method is to reduce creating connections to databases etc. in the doPipe() method. As much as possible class-instantiating should take place in the configure() method, to improve performance.

Specified by:

configure in interface IConfigurable

Specified by:

configure in interface IPipe

Overrides:

configure in class AbstractPipe

Throws:

ConfigurationException

doPipe

public PipeRunResult doPipe(Message message,
                            PipeLineSession session)
                     throws PipeRunException

Description copied from class: AbstractPipe

This is where the action takes place. Pipes may only throw a PipeRunException, to be handled by the caller of this object.

Specified by:

doPipe in interface IPipe

Specified by:

doPipe in class AbstractPipe

Throws:

PipeRunException

consumesSessionVariable

public boolean consumesSessionVariable(String sessionKey)

Description copied from interface: IPipe

returns true if the pipe or one of its children use the named session variable. Callers can use this to determine if a message needs to be preserved.

Specified by:

consumesSessionVariable in interface IPipe

Overrides:

consumesSessionVariable in class AbstractPipe

setSessionKey

@Deprecated
 @ConfigurationWarning(value="Please use getInputFromSessionKey instead.")
public void setSessionKey(String sessionKey)

Deprecated.

setExpressionValue

public void setExpressionValue(String expressionValue)

a string to compare the result of the xpathexpression (or the input-message itself) to. if not specified, a non-empty result leads to the 'then'-forward, an empty result to 'else'-forward

setThenForwardName

public void setThenForwardName(String thenForwardName)

forward returned when 'true'

Default value

then

setElseForwardName

public void setElseForwardName(String elseForwardName)

forward returned when 'false'

Default value

else

setXpathExpression

public void setXpathExpression(String string)

xpath expression to be applied to the input-message. if not set, no transformation is done

setRegex

public void setRegex(String regex)

regular expression to be applied to the input-message (ignored if xpathexpression is specified). the input-message matching the given regular expression leads to the 'then'-forward

setXsltVersion

public void setXsltVersion(int xsltVersion)

If set to 2 or 3 a Saxon (net.sf.saxon) xslt processor 2.0 or 3.0 respectively will be used, otherwise xslt processor 1.0 (org.apache.xalan)

Default value

2

setNamespaceDefs

public void setNamespaceDefs(String namespaceDefs)

namespace defintions for xpathExpression. Must be in the form of a comma or space separated list of prefix=namespaceuri-definitions.

setNamespaceAware

public void setNamespaceAware(boolean b)

controls namespace-awareness of XSLT transformation

Default value

true
