Method Detail

values

public static ProgramOptionsUtils[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ProgramOptionsUtils c : ProgramOptionsUtils.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ProgramOptionsUtils valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

isPythonEntryPoint

public static boolean isPythonEntryPoint(org.apache.commons.cli.CommandLine line)

Returns:

True if the commandline contains "-py" or "-pym" options or comes from PyFlink shell, false otherwise.

containsPythonDependencyOptions

public static boolean containsPythonDependencyOptions(org.apache.commons.cli.CommandLine line)

Returns:

True if the commandline contains "-pyfs", "-pyarch", "-pyreq", "-pyexec", "-pypath" options, false otherwise.

createPythonProgramOptions

public static ProgramOptions createPythonProgramOptions(org.apache.commons.cli.CommandLine line)
                                                 throws CliArgsException

Throws:

CliArgsException
