Method Detail

setAcceptsInlineText

protected static void setAcceptsInlineText(String fname,
                                           boolean text)

addAlias

protected static void addAlias(String from,
                               String to)

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

Overrides:

setElementType in class FlowNode

getCanonicalName

public String getCanonicalName()

function

public Object function(VariableStack stack)
                throws ExecutionException

Specified by:

function in class AbstractFunction

Throws:

ExecutionException

currenttime

public long currenttime(VariableStack stack)
                 throws ExecutionException

Throws:

ExecutionException

getArgs

public Number[] getArgs(VariableStack stack)
                 throws ExecutionException

Throws:

ExecutionException

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

Overrides:

acceptsInlineText in class FlowNode

getCanonicalType

public Object getCanonicalType()

Overrides:

getCanonicalType in class FlowNode

setQuotedArgs

protected static void setQuotedArgs(String fn)

initializeStatic

protected void initializeStatic()

Overrides:

initializeStatic in class AbstractSequentialWithArguments
