Field Detail

TYPE_EXP

public static final int TYPE_EXP

This statement is an expression statement. Has: expression. Please note that there are such things as empty empression statements. Example: ";". In those cases, getExpression() will actually return null.

Call getDataValue() to find out exactly which type of expression statement this is. If the data value == 0, then this is just an ordinary expression statement. Otherwise, refer to PlsqlSyntaxRecognizer.isExpressionStatementPrefix().

Method Detail

getStmtType

public int getStmtType()

Returns:

the type of this statement, see enumerated constants.

getBlock

public CodeBlockSymbol getBlock()

If this is a block statement, get the block for this statement.

getExpression

public ExpressionSymbol getExpression()

If this statement has an associate expression, get the expression for this statement.

getLabel

public NameSymbol getLabel()

Returns:

The NameSymbol array corresponding to this statement's label. Unlike all the other parse tree API array calls, this returns null if there are no labels. This is because labels rarely occur and there's no point creating a zero-length array for each statement.
