Class StatementFinder

java.lang.Object

com.pivotal.gemfirexd.internal.impl.tools.ij.StatementFinder

public class StatementFinder
extends Object

StatementGrabber looks through an input stream for the next JSQL statement. A statement is considered to be any tokens up to the next semicolon or EOF.

Semicolons inside comments, strings, and delimited identifiers are not considered to be statement terminators but to be part of those tokens.

Comments currently recognized include the SQL comment, which begins with "--" and ends at the next EOL, and nested bracketed comments.

Strings and delimited identifiers are permitted to contain newlines; the actual IJ or JSQL parsers will report errors when those cases occur.

There are no escaped characters, i.e. "\n" is considered to be two characters, '\' and 'n'.

Constructor Detail

StatementFinder

public StatementFinder(com.pivotal.gemfirexd.internal.iapi.tools.i18n.LocalizedInput s,
               com.pivotal.gemfirexd.internal.iapi.tools.i18n.LocalizedOutput promptDest,
               String basePath,
               Map<String,String> params)

The constructor does not assume the stream is data input or buffered, so it will wrap it appropriately. If the StatementFinder's input stream is connected to System.in, a LocalizedOutput stream may be given to print line continuation prompts when StatementFinder reads a newline.

Parameters:

s - the input stream for reading statements from.

promptDest - LocalizedOutput stream to write line continuation prompts ("> ") to. If null, no such prompts will be written.

basePath - TODO

Method Detail

getConsoleReader

public scala.tools.jline.console.ConsoleReader getConsoleReader()

getInput

public com.pivotal.gemfirexd.internal.iapi.tools.i18n.LocalizedInput getInput()

ReInit

public void ReInit(com.pivotal.gemfirexd.internal.iapi.tools.i18n.LocalizedInput s)

Reinit is used to redirect the finder to another stream. The previous stream should not have been in a PEEK state. If an output stream was given when constructing this StatementFinder and the input is standard input, continuation prompting will be enabled.

Parameters:

s - the input stream for reading statements from.

close

public void close()
           throws IOException

Throws:

IOException

nextStatement

public String nextStatement(com.pivotal.gemfirexd.internal.impl.tools.ij.ConnectionEnv connEnv,
                   com.pivotal.gemfirexd.internal.iapi.tools.i18n.LocalizedOutput out)

get the next statement in the input stream. Returns it, dropping its closing semicolon if it has one. If there is no next statement, return a null.

Returns:

the next statement in the input stream.
