Method Detail

createConfig

public static WoodyPipelineConfig createConfig(Map objectModel,
                                               Parameters parameters)

Creates and initializes a WoodyPipelineConfig object based on the passed arguments of the setup() of the specific Pipeline-component.

Parameters:

objectModel - the objectmodel as passed in the setup()

parameters - the parameters as passed in the setup()

Returns:

an instance of WoodyPipelineConfig initialized according to the settings in the sitemap.

findForm

public Form findForm()
              throws SAXException

Overloads findForm(String) by setting the jxpath-expression to null

Throws:

SAXException

findForm

public Form findForm(String jxpathExpression)
              throws SAXException

Finds the form from the current request-context based on the settings of this configuration object. The fall-back search-procedure is as follows:

1. Use the provided jxpathExpression (if not null)
2. Use the setting of the 'attribute-name' parameter on the request
3. Obtain the form from it's default location in the flow context

Parameters:

jxpathExpression - that should be pointing to the form

Returns:

the found form if found

Throws:

SAXException - in any of the following cases:

• The provided jxpathExpression (if not null) not point to a Form instance.
• The request is not holding a Form instance under the key specified by 'attribute-name' (if specified)
• Both jxpathExpression and 'attribute-name' were not specified AND also the default location was not holding a valid Form instance.

translateText

public String translateText(String original)

Replaces JXPath expressions embedded inside #{ and } by their value. This will parse the passed String looking for #{} occurences and then uses the evaluateExpression(String) to evaluate the found expression.

Returns:

the original String with it's #{}-parts replaced by the evaulated results.

evaluateExpression

public Object evaluateExpression(String expression)

Evaluates the passed xpath expression using the internal jxpath context holding the declared variables:

1. continuation: as made available by flowscript
2. request: as present in the cocoon processing environment
3. session: as present in the cocoon processing environment
4. parameters: as present in the cocoon sitemap node of the pipeline component

Parameters:

expression -

Returns:

the object-value resulting the expression evaluation.

getLocale

public Locale getLocale()

setLocale

public void setLocale(Locale locale)

getLocaleParameter

public Locale getLocaleParameter()

getFormAction

public String getFormAction()

The value for the wi:form-generated/@action. Note: wi:form-template copies this from its wt:form-template counterpart.

Returns:

the translateText(String) result of the 'form-action' sitemap parameter to the pipeline component, or null if that parameter was not set.

getFormMethod

public String getFormMethod()

The value for the wi:form-generated/@method. Note: wi:form-template copies this from its wt:form-template counterpart.

Returns:

the value of the 'form-method' sitemap parameter to the pipeline component. Defaults to 'POST' if it was not set.

getFormAttributes

public Attributes getFormAttributes()

The grouped attributes to set on the wi:form-generated element. Note: wi:form-template copies this from its wt:form-template counterpart.
