Class PlsqlParser

java.lang.Object
  oracle.javatools.parser.plsql.old.PlsqlParser

public class PlsqlParser
extends java.lang.Object

Entrypoint into the Plsql parser. In this preliminary version, you can only parse full Plsql files (i.e. no expression parsing) and it only parses procedure/function in the root, local variables in the block declarations, and for loops in the statements.

Field Detail

ERRORS_CHOKE

public static final boolean ERRORS_CHOKE

Error handling. If there are any syntax errors, the parser will return null. Otherwise, the parser will return a well-formed parse tree.

Constant Field Values

ERRORS_REPORT

public static final boolean ERRORS_REPORT

Error handling. If there are any syntax errors, the parser will generate error Strings and generate as much of the parse tree as possible. The client will be able to retrieve the array of error Strings from the returned parse tree JavaSymbol. If there are any errors, it is almost guaranteed the tree will NOT be well-formed. In rare cases, the parser may simply return null.

Constant Field Values

INPUT_PLSQL_FILE

public static final int INPUT_PLSQL_FILE

Input type. The input is a Plsql file. The parser will return a RootSymbol.

See Also:

Constant Field Values

INPUT_EXPR

public static final int INPUT_EXPR

Input type. The input is an expression. The parser will return a ExpressionSymbol.

Constant Field Values

DEPTH_DECLARATIONS

public static final int DEPTH_DECLARATIONS

Parse depth. Parses for functions, procedures, packages and package bodies. Within each type of global declaration, you'll get type declarations and local variable declarations. You'll also get all the various control statements in the code blocks: if, loop, while, and for. You'll get all nested blocks so that you can find all local variables in the Plsql file. No expression parsing is done and next to no sql parsing is done.

Constant Field Values

DEPTH_FULL

public static final int DEPTH_FULL

Parse depth. Fully parses the input.

Parses according to default parsing options.

parse

public static ErrorReporter parse(ReadTextBuffer buffer,
                                  PlsqlParser.ParsingOptions options)

Parses according to the specified parsing options. May or may not return null according to the ParsingOptions.reportErrors option. Returns either a RootSymbol or an ExpressionSymbol.
