BadExpression(AbstractExpression parent,
AbstractExpression expression)
Creates a new
BadExpression. |
| Modifier and Type | Method and Description |
|---|---|
void |
accept(ExpressionVisitor visitor)
Visits this
Expression by the given visitor. |
void |
acceptChildren(ExpressionVisitor visitor)
Visits the children of this
Expression. |
protected void |
addChildrenTo(java.util.Collection<Expression> children)
Adds the children of this
AbstractExpression to the given collection. |
protected void |
addOrderedChildrenTo(java.util.List<Expression> children)
Adds the children of this
AbstractExpression to the given list. |
JPQLQueryBNF |
findQueryBNF(Expression expression)
Retrieves the
JPQLQueryBNF that represents the fragment of this Expression
that was used when parsing the given Expression. |
Expression |
getExpression()
Returns the
Expression that was parsed but grammatically, it is not a valid location. |
JPQLQueryBNF |
getQueryBNF()
Returns the BNF of this
Expression. |
protected 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.
|
protected boolean |
isUnknown()
Determines whether this expression is an unknown
Expression or any other subclass. |
protected void |
parse(WordParser wordParser,
boolean tolerant)
Parses the query by starting at the current position, which is part of the given
WordParser. |
protected void |
toParsedText(java.lang.StringBuilder writer,
boolean actual)
Generates a string representation of this
Expression, including its children,
if it has any. |

BadExpression.parent - The parent of this expressionpublic BadExpression(AbstractExpression parent, AbstractExpression expression)
BadExpression.parent - The parent of this expressionexpression - The Expression that was parsed in a location that was not supposed
to contain that expressionpublic void accept(ExpressionVisitor visitor)
Expression by the given visitor.visitor - The ExpressionVisitor to visit this objectpublic void acceptChildren(ExpressionVisitor visitor)
Expression. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children() is called.
This does not traverse the Expression sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor in order to traverse the entire sub-hierarchy.
visitor - The visitor to visit the children of this object.protected void addChildrenTo(java.util.Collection<Expression> children)
AbstractExpression to the given collection.addChildrenTo in class AbstractExpressionchildren - The collection used to store the childrenprotected void addOrderedChildrenTo(java.util.List<Expression> children)
AbstractExpression to the given list.addOrderedChildrenTo in class AbstractExpressionchildren - The list used to store the string representation of this AbstractExpressionpublic JPQLQueryBNF findQueryBNF(Expression expression)
JPQLQueryBNF that represents the fragment of this Expression

Expression that was parsed but grammatically, it is not a valid location.public JPQLQueryBNF getQueryBNF()
Expression.JPQLQueryBNF, which represents the grammar of this Expressionprotected boolean isParsingComplete(WordParser wordParser, java.lang.String word, Expression expression)
isParsingComplete in class AbstractExpressionwordParser - The text to parse based on the current position of the cursorword - The word that was retrieved from the given text, which is the first word in the textexpression - The Expression that has already been parsedtrue if the text no longer can't be parsed by the current expression;
false if more can be parsedprotected boolean isUnknown()
Expression or any other subclass.isUnknown in class AbstractExpressionfalse by defaultprotected void parse(WordParser wordParser, boolean tolerant)
WordParser.parse in class AbstractExpressionwordParser - The text to parse based on the current position of the cursortolerant - Determines whether the parsing system should be tolerant, meaning if it should
try to parse invalid or incomplete queriesprotected void toParsedText(java.lang.StringBuilder writer,
boolean actual)
Expression, including its children,
if it has any.toParsedText in class AbstractExpressionwriter - The buffer used to append this Expression's string representationactual - Determines whether the string representation should represent what was parsed,
i.e. include any "virtual" whitespace (such as ending whitespace) and the actual case of the
JPQL identifiers
