Method Detail

addElement

public void addElement(FlowElement element)

Description copied from interface: FlowElement

Adds a child element to this element. The child element is added at the end of the list of child elements

Specified by:

addElement in interface FlowElement

replaceElement

public void replaceElement(int index,
                           FlowElement element)

Description copied from interface: FlowElement

Replaces the child element at @param index with

Specified by:

replaceElement in interface FlowElement

removeElement

public void removeElement(int index)

Description copied from interface: FlowElement

Removes the child element at @param index. The elements with indexes > @param index will be shifted down in the list

Specified by:

removeElement in interface FlowElement

getElement

public FlowElement getElement(int index)

Description copied from interface: FlowElement

Returns the child element at @param index

Specified by:

getElement in interface FlowElement

elementCount

public int elementCount()

Description copied from interface: FlowElement

Returns the number of child elements for this element

Specified by:

elementCount in interface FlowElement

elements

public List elements()

Description copied from interface: FlowElement

Returns the list of child elements

Specified by:

elements in interface FlowElement

setElementType

public void setElementType(String type)

Description copied from interface: FlowElement

Sets the element type. The element type is a string reflecting the actual name used in source files.

Specified by:

setElementType in interface FlowElement

getElementType

public String getElementType()

Description copied from interface: FlowElement

Returns the type of this element

Specified by:

getElementType in interface FlowElement

setProperty

public void setProperty(String name,
                        Object value)

Description copied from interface: FlowElement

Sets a property on this element. The value can be null

Specified by:

setProperty in interface FlowElement

removeProperty

public void removeProperty(String name)

Description copied from interface: FlowElement

Completely removes a property previously set on this element. If no property with the given name exists, removeProperty will have no effect.

Specified by:

removeProperty in interface FlowElement

getProperty

public Object getProperty(String name)

Description copied from interface: FlowElement

Retrieves the value of a property. If no property with the given name exists, getProperty will return null. In order to distinguish between a property with a value of null and a property not set, hasProperty can be used.

Specified by:

getProperty in interface FlowElement

hasProperty

public boolean hasProperty(String name)

Description copied from interface: FlowElement

Returns true if a property with the given name was set on this element.

hasProperty in interface FlowElement

propertyNames

public Collection propertyNames()

Description copied from interface: FlowElement

Returns a collection of all the property names that are set on this element.

Specified by:

propertyNames in interface FlowElement

setParent

public void setParent(FlowElement parent)

Description copied from interface: FlowElement

Sets the lexical parent of this element. When adding a child element with addElement, setParent is automatically called on the child element with this element as the argument.

Specified by:

setParent in interface FlowElement

getParent

public FlowElement getParent()

Description copied from interface: FlowElement

Retrieves the parent previously set with setParent

Specified by:

getParent in interface FlowElement

failImmediately

public void failImmediately(VariableStack stack,
                            String message)

Description copied from interface: FlowElement

Provides means to cause the execution of this element under the given context (stack) to fail

Specified by:

failImmediately in interface FlowElement

Throws:

ExecutionException

getProjectNode

public ProjectNode getProjectNode()

acceptsInlineText

public boolean acceptsInlineText()

Description copied from interface: FlowElement

Returns true if the implementation of this element makes use of inline XML text. XML unfortunately does not provide means to separate relevant inline text from formatting whitespace (which in itself may or may not be relevant, depending on the context).

Specified by:

acceptsInlineText in interface FlowElement

event
