Constructor Detail

AndExpression

AndExpression(AbstractExpression parent)

Creates a new AndExpression.

Parameters:

parent - The parent of this expression

Method Detail

accept

public void accept(ExpressionVisitor visitor)

Visits this Expression by the given visitor.

Parameters:

visitor - The visitor to visit this object

isParsingComplete

boolean isParsingComplete(WordParser wordParser,
                          java.lang.String word,
                          Expression expression)

Determines whether the parsing is complete based on what is left in the given text. The text is never empty.

Overrides:

isParsingComplete in class LogicalExpression

Parameters:

wordParser - The text to parse based on the current position of the cursor

word - The word that was retrieved from the given text, which is the first word in the text

expression - The Expression that has already been parsed

Returns:

true if the text no longer can't be parsed by the current expression; false if more can be parsed

rightExpressionBNF

public JPQLQueryBNF rightExpressionBNF()

Returns the BNF used to determine how to parse the right expression.

Specified by:

rightExpressionBNF in class CompoundExpression

Returns:

The BNF used when parsing the expression after the identifier
