Method Detail

applyToConsumerRP

public static Object applyToConsumerRP(Procedure proc,
                                       CallContext ctx)
                                throws Throwable

Throws:

Throwable

error

protected static void error(String message)

doit

public static void doit(ArgListVector args,
                        Consumer consumer)
                 throws Throwable

Throws:

Throwable

tokenize

public static void tokenize(String str,
                            boolean useShell,
                            List<String> arr)

Parse strings into token, handling substitution marks.

Parameters:

useShell - true if result will be further tokenized by a shell. (In this case we're basically just handling substiution marks.)

getInputStreamFrom

public static InputStream getInputStreamFrom(Object val)

copyStream

public static void copyStream(InputStream in,
                              OutputStream out,
                              boolean closeOut)
                       throws IOException

Copy bytes from InputStream to OutputStream using current Thread. Continue copying until EOF or exception. At end, the input stream is closed, but the output stream is not.

Throws:

IOException
