Constructor Detail

EjenStylesheetNode

public EjenStylesheetNode()

Method Detail

getAttributes

public Properties getAttributes()

Returns all non null attributes of this EjenStylesheetNode.

Overrides:

getAttributes in class EjenChildNode

Returns:

non null attributes of this EjenStylesheetNode.

getChildren

public Vector getChildren()

Returns all child nodes of this EjenStylesheetNode (include, import or param).

Overrides:

getChildren in class EjenChildNode

Returns:

all child nodes of this EjenStylesheetNode.

setFile

public void setFile(String file)

[mandatory/AVT] - sets the file attribute.

Parameters:

file - name of the XSL file stylesheet to be used as filter, template, include or import.

createParam

public EjenParamNode createParam()

Creates a new param node and appends it to the list of current child nodes of this EjenStylesheetNode.

Returns:

the new param node.

createInclude

public EjenIncludeNode createInclude()

Creates a new include node and appends it to the list of current child nodes of this EjenStylesheetNode.

Returns:

the new include node.

createImport

public EjenImportNode createImport()

Creates a new import node and appends it to the list of current child nodes of this EjenStylesheetNode.

Returns:

the new import node.

check

public void check()

Checks this EjenStylesheetNode for mandatory attributes.

Overrides:

check in class EjenChildNode

Throws:

EjenException - if file attribute is not set or if any call to the check() method of a child node fails.

beforeProcess

public void beforeProcess()

Prepares this EjenStylesheetNode execution. Creates a new Transformer with the stylesheet whose name is provided by the file attribute and pushes a new context onto the context stack.

Overrides:

beforeProcess in class EjenChildNode

process

public void process()

Executes this EjenStylesheetNode (and all child nodes). This method is called by the process() method in each implementation of the EjenStylesheetNode abstract class.

Overrides:

process in class EjenChildNode

afterProcess

public void afterProcess()

Pops the context that has been pushed by the beforeProcess() method.

Overrides:

afterProcess in class EjenChildNode
