Method Details

interpretPyArgs

public static PyArgumentMap interpretPyArgs(org.python.core.PyObject[] args,
 String[] keywords,
 Class<?> callingClass,
 String methodName)

Helper for scripting functions that want to use python's keyword-style function invocation. This version uses reflection to look for the @KeywordArgs annotation to find the expected params and their types.

interpretPyArgs

public static PyArgumentMap interpretPyArgs(org.python.core.PyObject[] args,
 String[] keywords,
 String[] expectedKeywords,
 Class<?>[] expectedTypes)

Throws:

ClassCastException - if an argument failed to be coerced into the expected type based on expectedTypes

empty

public static PyArgumentMap empty()

getStringArray

@Nullable
public String[] getStringArray(String name,

getStringArg

@Nullable
public String getStringArg(String name,

def - a fallback value to be used if the specified keyword was not present in the PyArgumentMap

Returns:

the argument as a String, or the fallback value def.

Throws:

ClassCastException - if the argument is present but cannot be coerced to the expected type.

getIntArg

@Nullable
public Integer getIntArg(String name)

Parameters:

name - keyword name of argument to retrieve. If not invoked with kwargs, will return the parameter at the expected numeric index.

Returns:

the argument as an Integer, or null if the invocation passed null.

Throws:

ClassCastException - if the argument is present but cannot be coerced to the expected type.

getIntArg

@Nullable
public Integer getIntArg(String name,
 Integer def)

Parameters:

name - keyword name of argument to retrieve. If not invoked with kwargs, will return the parameter at the expected numeric index.

def - a fallback value to be used if the specified keyword was not present in the PyArgumentMap

Throws:

ClassCastException - if the argument is present but cannot be coerced to the expected type.

getLongArg

@Nullable
public Long getLongArg(String name)

Parameters:

name - keyword name of argument to retrieve. If not invoked with kwargs, will return the parameter at the expected numeric index.

Returns:

the argument as a Long, or null if the invocation passed null.

Throws:

ClassCastException - if the argument is present but cannot be coerced to the expected type.

getLongArg

@Nullable
public Long getLongArg(String name,
 Long def)

Parameters:
