Method Detail

getFunctionName

public java.lang.String getFunctionName()
Description copied from class: ExNode
Nodes representing functions must have a name. This name is used in the formatting of default trace messages and the default XML rendering. If a node doesn't have a name for some reason, or needs more control over the trace messges and XML, they must overload beginTrace, endTrace, and toXml below.

Specified by:
getFunctionName in class ExNode

evalInternal

protected ExValue evalInternal(ExState state)
                        throws WavesetException
Description copied from class: ExNode
Abstract evaluation method all nodes must have. Implementations of evalInternal need not (and should not) perform any tracing/breakpoints. This is all handled by the calling method eval.

Specified by:
evalInternal in class ExNode
Throws:
WavesetException
