InputParameter(AbstractExpression parent,
java.lang.String parameter)
Creates a new
InputParameter. |
| 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 |
addOrderedChildrenTo(java.util.List<Expression> children)
Adds the children of this
AbstractExpression to the given list. |
java.lang.String |
getParameter()
Returns the positional parameter or the named parameter, which includes the identifier.
|
java.lang.String |
getParameterName()
Returns the positional parameter or the named parameter without the identifier.
|
JPQLQueryBNF |
getQueryBNF()
Returns the BNF of this
Expression. |
boolean |
isNamed()
Determines whether this parameter is a positional parameter, i.e. the parameter type is '?'.
|
boolean |
isPositional()
Determines whether this parameter is a positional parameter, i.e. the parameter type is ':'.
|
protected void |
parse(WordParser wordParser,
boolean tolerant)
Parses the query by starting at the current position, which is part of the given
WordParser. |
java.lang.String |
toActualText()
Generates a string representation of this
Expression, which needs to include any
characters that are considered virtual, i.e. that was parsed when the query is incomplete and
is needed for functionality like content assist. |
java.lang.String |
toParsedText()
Returns a string representation of this
Expression and its children. |
protected void |
toParsedText(java.lang.StringBuilder writer,
boolean actual)
Generates a string representation of this
Expression, including its children,
if it has any. |

InputParameter.parent - The parent of this expressionparameter - The input parameter, which starts with either '?' or ':'public 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 addOrderedChildrenTo(java.util.List<Expression> children)

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 queriespublic java.lang.String toActualText()
Expression, which needs to include any
characters that are considered virtual, i.e. that was parsed when the query is incomplete and
is needed for functionality like content assist.toActualText in interface ExpressiontoActualText in class AbstractExpressionExpressionpublic java.lang.String toParsedText()
Expression and its children. The expression
should contain whitespace even if the beautified version would not have any. For instance,
"SELECT e " should be returned where Expression.toParsedText() would return "SELECT e".toParsedText in interface ExpressiontoParsedText in class AbstractExpressionExpressionprotected 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
