LocalDateTime
public LocalDateTime(AbstractExpression parent)
Creates a newLocalExpression
.- Parameters:
parent
- The parent of this expression
-
-
Method Detail
-
accept
public void accept(ExpressionVisitor visitor)
Description copied from interface:Expression
Visits thisExpression
by the givenvisitor
.- Parameters:
visitor
- TheExpressionVisitor
to visit this object
-
addChildrenTo
protected void addChildrenTo(Collection<Expression> children)
Description copied from class:AbstractExpression
Adds the children of thisAbstractExpression
to the given collection.- Overrides:
addChildrenTo
in classAbstractExpression
- Parameters:
children
- The collection used to store the children
-
acceptChildren
public void acceptChildren(ExpressionVisitor visitor)
Description copied from interface:Expression
Visits the children of thisExpression
. This method can be used to optimize traversing the children since a new list is not created every timeExpression.children()
is called.This does not traverse the
Expression
sub-hierarchy, use a subclass ofAbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.- Parameters:
visitor
- Thevisitor
to visit the children of this object.
-
addOrderedChildrenTo
protected void addOrderedChildrenTo(List<Expression> children)
Description copied from class:AbstractExpression
Adds the children of thisAbstractExpression
to the given list.- Overrides:
addOrderedChildrenTo
in classAbstractExpression
- Parameters:
children
- The list used to store the string representation of thisAbstractExpression
-
parse
protected void parse(WordParser wordParser, boolean tolerant)
Description copied from class:AbstractExpression
Parses the query by starting at the current position, which is part of the givenWordParser
.- Specified by:
parse
in classAbstractExpression
- Parameters:
wordParser
- 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 queries
-
runByType
public void runByType(Runnable dateAction, Runnable timeAction, Runnable dateTimeAction)
Execute action depending on local date/time text identifier inLocalDateTime
expression.- Parameters:
dateAction
- function executed forLOCAL DATE
timeAction
- function executed forLOCAL TIME
dateTimeAction
- function executed forLOCAL DATETIME
-
getValueByType
public <R> R getValueByType(Supplier<R> dateAction, Supplier<R> timeAction, Supplier<R> dateTimeAction)
Execute supplier depending on local date/time text identifier inLocalDateTime
expression.- Parameters:
dateAction
- function executed forLOCAL DATE
timeAction
- function executed forLOCAL TIME
dateTimeAction
- function executed forLOCAL DATETIME
-
getQueryBNF
public JPQLQueryBNF getQueryBNF()
Description copied from interface:Expression
Returns the BNF of thisExpression
.- Returns:
- The
JPQLQueryBNF
, which represents the grammar of thisExpression
-
toParsedText
protected void toParsedText(StringBuilder writer, boolean actual)
Description copied from class:AbstractExpression
Generates a string representation of thisExpression
, including its children, if it has any.- Specified by:
toParsedText
in classAbstractExpression
- Parameters:
writer
- The buffer used to append thisExpression
'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
-
toActualText
public String toActualText()
Description copied from interface:Expression
Generates a string representation of thisExpression
, 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.- Specified by:
toActualText
in interfaceExpression
- Overrides:
toActualText
in classAbstractExpression
- Returns:
- The string representation of this
Expression
