Method Details

invoke

public Object invoke(Function function,
 Object... args)

Description copied from interface: FunctionInvoker

Invoke function, it is a good practice to wrap any outgoing exceptions with SmartParamException with FUNCTION_INVOKE_ERROR reason.

Specified by:

invoke in interface FunctionInvoker

Parameters:

function - description of function to invoke

args - arguments

Returns:

evaluated value (can be null)

validate

public void validate(String name,
 String body,
 String args)

Validates function syntax using current, thread-bound interpreter. The exception is thrown if function's syntax is not correct.

clean

public void clean()

Cleans up all resources associated with the current thread. - runs python gc inside the CPython interpreter - closes the CPyton interpreter - using this method before the thread terminates is necessary to prevent a memory leak

invalidate

public void invalidate(int implId)

addGlobalObject

public void addGlobalObject(FunctionCode code,
 Object obj)

getThreadContext

public ThreadContext getThreadContext()

getInterpreterType

public PythonInterpreterType getInterpreterType()

getGlobalObjects

public Map<FunctionCode,Object> getGlobalObjects()

getPreparedFunctionCache

public Map<Integer,PreparedPythonFunction> getPreparedFunctionCache()
