public ParseOutput getOrCreateParseOutput(java.lang.String debugFileName,
                                          boolean isXml)

This method should be used by those who are parsing small bits of Idoc script. By reusing the parse output object, a factor x4 or more speed increase can be realized. Note, the object DynamicHtmlMerger object is NOT thread safe. You must have a different ParseOutput object created per thread of execution.

                             throws java.lang.IllegalArgumentException

Create an exception that reports the location of an error during runtime processing of script. This error is in the internal processing of an element and gives offsets into the string that produced the GrammarElement object. The method createErrorMessage is the high level message that reports the location of the GrammarElement inside the file.

getExecutionContext

public ExecutionContext getExecutionContext()

Gets the current execution context associated with this merger.

setExecutionContext

public void setExecutionContext(ExecutionContext cxt)

Beware. If the ExecutionContext you supply isn't fairly complete, you may have objects like PageMerger explode on you. A wise idea is to wrap the ExecutionContext returned by getExecutionContext() in an ExecutionContextAdaptor and set that into this DynamicHtmlMerger.

addDataMerger

public void addDataMerger(DataMergerImplementor mergerImplementor)

Adds a callback interface allowing selective evaluation of result sets.

getIsTracingScript

public boolean getIsTracingScript()

Gets value of flag that turns on/off whether or not script is traced.

Turns on/off flag that controls whether or not script is traced.

getIsViewablePageOutput

public boolean getIsViewablePageOutput()

Gets value of flag that turns on/off whether or not this script is being executed in a context where at least some of the result will be directly viewable by a user or administrator. This flag should be false only if the script is being used to control internal logic or set variables.

Turns on/off flag that controls output is meant to be viewable.

getErrorTrace

public java.lang.String getErrorTrace()
