All Implemented Interfaces:

ParsingState

public class OracleNormalParsingState
extends NormalParsingState

The initial state for Oracle. This parser adds PL/SQL statement recognition to the parser. In order for the parser to recognize the ending of a code block, the SQLPlus standard must be followed, namely every code block should end with line containing a single forward slash (/).

Method Detail

getNextParsingState

protected ParsingState getNextParsingState(char previousChar,
                                           char currentChar,
                                           char nextChar,
                                           StatementBuilder statementBuilder)

Overridden to also correctly identify the starting of PL/SQL code blocks and to handle slashes / to end a statement.

Overrides:

getNextParsingState in class NormalParsingState

Parameters:

previousChar - The previous char, 0 if none

currentChar - The current char

nextChar - The next char, 0 if none

statementBuilder - The statement builder, not null

Returns:

The next parsing state, null if the end of the statement is reached

isStartOfCodeStatement

protected boolean isStartOfCodeStatement(StringBuilder statement)

Checks whether the statment contains the starting letters of a code statement (eg CREATE PACKAGE). The statementBuffer should contain all letters (no signs) and every double space or newline converted to a single space.

Parameters:

statement - The buffer, not null

Returns:

True if a code statment is recognized

matches

protected boolean matches(String text,
                          StringBuilder statement)

Utility method to check whether the given statement starts with the letters of the given text.

Parameters:

text - The starting letters, not null

statement - The statement to check

Returns:

True if the statement starts with the text
