public ConcurrentTestCommandScript.CommandParser()

Method Detail

rememberVariableRebindings

public void rememberVariableRebindings(List<String> pairs)

applyVariableRebindings

private void applyVariableRebindings()

trace

private void trace(String prefix,
                   Object message)

trace

private void trace(String message)

load

private void load(String scriptFileName)
           throws IOException

Parses a multi-threaded script and converts it into test commands.

Throws:

IOException

doEndOfState

private void doEndOfState(String state)

defineVariables

private void defineVariables(String line)

lookupState

private Map<String,String> lookupState(String state)

Manages state transitions. Converts a state name into a map. Map keys are the names of available commands (e.g. @sync), and map values are the state to switch to open seeing the command.

firstWord

private String firstWord(String trimmedLine)

Returns the first word of the given line, assuming the line is trimmed. Returns the characters up the first non-whitespace character in the line.

skipFirstWord

private String skipFirstWord(String trimmedLine)

Returns everything but the first word of the given line, assuming the line is trimmed. Returns the characters following the first series of consecutive whitespace characters in the line.

readLine

private String readLine(String line,
                        BufferedReader in)
                 throws IOException

Returns an input line, possible extended by the continuation character (\). Scans the script until it finds an un-escaped newline.

Throws:

private String readSql(String startOfSql,
                       BufferedReader in)
                throws IOException

Returns a block of SQL, starting with the given String. Returns startOfSql concatenated with each line from in until a line ending with a semicolon is found.
