clearParameters

public void clearParameters()

Remove all current values bound to input or output variables.

clearPinnedData

public void clearPinnedData()

Remove all references to pinned variables from this script. Note: this *does not* remove the underlying data. It merely removes a reference to it from this prepared script. This is useful if you want to maintain an independent cache of weights and allow the JVM to garbage collect under memory pressure.

executeScript

public ResultVariables executeScript()

Executes the prepared script over the bound inputs, creating the result variables according to bound and registered outputs.

Returns:

ResultVariables object encapsulating output results

explain

public String explain()

Explain the DML/PyDML program and view result as a string.

Returns:

string results of explain

getLineageTrace

public String getLineageTrace(String var)

Capture lineage of the DML/PyDML program and view result as a string.

Parameters:

var - the output variable name on which lineage trace is sought

Returns:

string results of lineage trace

statistics

public String statistics()

Return a string containing runtime statistics. Note: these are not thread local and will reflect execution in all threads

Returns:

string containing statistics

enableFunctionRecompile

public void enableFunctionRecompile(String fnamespace,
                                    String... fnames)

Enables function recompilation, selectively for the given functions. If dynamic recompilation is globally enabled this has no additional effect; otherwise the given functions are dynamically recompiled once on every entry but not at the granularity of individually last-level program blocks. Use this fine-grained recompilation option for important functions in small-data scenarios where dynamic recompilation overheads might not be amortized.

Parameters:

fnamespace - function namespace, null for default namespace

fnames - function name

clone

public PreparedScript clone(boolean deep)

Creates a cloned instance of the prepared script, which allows for concurrent execution without side effects.

Parameters:

deep - indicator if a deep copy needs to be created; if false, only a shallow (i.e., by reference) copy of the program and read-only meta data is created.

Returns:

an equivalent prepared script

clone

public Object clone()

Overrides:

clone in class Object
