Field Detail

LEVEL_ROOT

public static final int LEVEL_ROOT

In root level, parsing is done on a full Plsql file. Parsing recognizes all the various types of code blocks and has some limited understanding of statements and variables. More specifically, this is the minimal amount of parsing to obtain all local variables and type declarations.

Constant Field Values

LEVEL_EXPRESSION

public static final int LEVEL_EXPRESSION

In expression level, all parsing options are enabled.

See Also:

Constant Field Values

INPUT_ROOT

public static final int INPUT_ROOT

The input buffer contains a full Plsql file.

See Also:

Constant Field Values

INPUT_EXPRESSION

public static final int INPUT_EXPRESSION

The input buffer contains an expression.

startLevel

protected int startLevel

Constructor Detail

PlsqlSyntaxRecognizer

public PlsqlSyntaxRecognizer()

Method Detail

newRecognizer

public static PlsqlSyntaxRecognizer newRecognizer()

Instantiates a new recognizer that starts at the root and will do a full Plsql parse.

Returns:

the newly created PlsqlSyntaxRecognizer

newRecognizer

public static PlsqlSyntaxRecognizer newRecognizer(int startLevel,
                                  int depthLevel)

Instantiates a new recognizer that starts at the given depth and will parse down to the given depth.

Parameters:

startLevel - the parse level to start parsing at. LEVEL_ROOT is for parsing a Plsql file, LEVEL_EXPRESSION is for parsing an expression.

depthLevel - the parse level to parse down to. LEVEL_ROOT will parse down to but not into code blocks. LEVEL_EXPRESSION will do a full Java parse.

Returns:

the newly created JavaSyntaxRecognizer

isKeywordToken

public static final boolean isKeywordToken(int token)

Returns:

True if this is a Pl/sql keyword.

isLiteralToken

public static final boolean isLiteralToken(int token)

Returns:

True if this is a Pl/sql literal.

isPrefixOperator

public static final boolean isPrefixOperator(int token)

Returns:

True if this is a prefix operator in Pl/sql.

isSuffixOperator

public static final boolean isSuffixOperator(int token)

Returns:

True if this is a prefix operator in Pl/sql.

isInfixOperator

public static final boolean isInfixOperator(int token)

Returns:

True if this is an infix operator in Pl/sql.

isSpecialOperator

public static final boolean isSpecialOperator(int token)

Returns:

True if this is a special operator operator in Pl/sql.

isExpressionStatementPrefix

public static final boolean isExpressionStatementPrefix(int token)

Simple expression statements can be described as either "keyword;" or "keyword expression;".

Returns:

True if this is a keyword prefix for simple expression statements.

isSqlStatementPrefix

public static final boolean isSqlStatementPrefix(int token)

Returns:

True if this is a keyword prefix for sql statements.

nextTokenIdentifier

protected final void nextTokenIdentifier(java.lang.String id,
                       java.lang.String id2)

nextTokenIdentifier

parse

public void parse()

Description copied from class: AbstractSyntaxRecognizer

Does the parse. Should not emit the SYNTAX_ROOT beginning to start off, but it should emit the SYNTAX_ROOT ending at the end.

Specified by:

parse in class AbstractSyntaxRecognizer

instantiatePreferredLexer

public Lexer instantiatePreferredLexer()

Description copied from class: AbstractSyntaxRecognizer

Subclasses should instantiate and customize preferred lexers here.

Specified by:

instantiatePreferredLexer in class AbstractSyntaxRecognizer

errorExpecting

protected void errorExpecting(int token)

Description copied from class: AbstractSyntaxRecognizer

Generates an error-expecting token. Sub-classes should override and report a more descriptive syntax error.

Overrides:

errorExpecting in class AbstractSyntaxRecognizer

_codeToString

public java.lang.String _codeToString(int code)

Description copied from class: AbstractSyntaxRecognizer

Converts the syntax code into a string.

Overrides:
