Interface ExecBinding

All Known Implementing Classes:

DefaultExecBinding

public interface ExecBinding

Represents the binding of input and output types of a ExecCommandExecutor to an Exchange. The input of the executor is an ExecCommand and the output is an ExecResult.

Field Summary

Fields

Modifier and Type	Field and Description
static String	EXEC_COMMAND_ARGS The header value overrides the existing command arguments in the ExecEndpoint URI.
static String	EXEC_COMMAND_EXECUTABLE The header value overrides the executable of the command, configured in the exec endpoint URI.
static String	EXEC_COMMAND_OUT_FILE Specifies the file name of a file, created by the executable, that should be considered as output of the executable, e.g.
static String	EXEC_COMMAND_TIMEOUT Specifies the amount of time, in milliseconds, after which the process of the executable should be terminated.
static String	EXEC_COMMAND_WORKING_DIR Sets the working directory of the EXEC_COMMAND_EXECUTABLE.
static String	EXEC_EXIT_VALUE The value of this header is the exit value that is returned, after the execution.
static String	EXEC_STDERR The value of this header is a InputStream with the standard error stream of the executable.
static String	EXEC_USE_STDERR_ON_EMPTY_STDOUT The value of this header is a boolean which indicates whether or not to fallback and use stderr when stdout is empty.

Method Summary

Modifier and Type	Method and Description
ExecCommand	readInput(Exchange exchange, ExecEndpoint endpoint) Creates a ExecCommand from the headers in the exchange and the settings of the endpoint.
void	writeOutput(Exchange exchange, ExecResult result) Populates the exchange form the ExecResult.

Field Detail

EXEC_COMMAND_EXECUTABLE

static final String EXEC_COMMAND_EXECUTABLE

The header value overrides the executable of the command, configured in the exec endpoint URI. As executable is considered the remaining of the ExecEndpoint URI;

e.g. in the URI exec:C:/Program Files/jdk/java.exe , C:/Program Files/jdk/java.exe is the executable.

Constant Field Values

EXEC_COMMAND_ARGS

static final String EXEC_COMMAND_ARGS

The header value overrides the existing command arguments in the ExecEndpoint URI. The arguments may be a List. In this case no parsing of the arguments is necessary.

#EXEC_COMMAND_EXECUTABLE}, Constant Field Values

EXEC_COMMAND_OUT_FILE

static final String EXEC_COMMAND_OUT_FILE

Specifies the file name of a file, created by the executable, that should be considered as output of the executable, e.g. a log file.

ExecResultConverter.toInputStream(ExecResult), Constant Field Values

EXEC_COMMAND_WORKING_DIR

static final String EXEC_COMMAND_WORKING_DIR

Sets the working directory of the EXEC_COMMAND_EXECUTABLE. The header value overrides any existing command in the endpoint URI. If this is not configured, the working directory of the current process will be used.

See Also:

Constant Field Values

EXEC_COMMAND_TIMEOUT

static final String EXEC_COMMAND_TIMEOUT

Specifies the amount of time, in milliseconds, after which the process of the executable should be terminated. The default value is Long.MAX_VALUE.

See Also:

Constant Field Values

EXEC_STDERR

static final String EXEC_STDERR

The value of this header is a InputStream with the standard error stream of the executable.

See Also:

Constant Field Values

EXEC_EXIT_VALUE

static final String EXEC_EXIT_VALUE

The value of this header is the exit value that is returned, after the execution. By convention a non-zero status exit value indicates abnormal termination.
Note that the exit value is OS dependent.

See Also:

Constant Field Values

EXEC_USE_STDERR_ON_EMPTY_STDOUT

static final String EXEC_USE_STDERR_ON_EMPTY_STDOUT

The value of this header is a boolean which indicates whether or not to fallback and use stderr when stdout is empty.

Constant Field Values

Method Detail

readInput

ExecCommand readInput(Exchange exchange,
                      ExecEndpoint endpoint)

Parameters:

exchange - a Camel Exchange

endpoint - an ExecEndpoint instance

Returns:

an ExecCommand object

writeOutput

void writeOutput(Exchange exchange,
                 ExecResult result)

Populates the exchange form the ExecResult.
