Constructor Details

LocalDateTime

public LocalDateTime(AbstractExpression parent)

Creates a new LocalExpression.

Parameters:

parent - The parent of this expression

Method Details

accept

public void accept(ExpressionVisitor visitor)

Description copied from interface: Expression

Visits this Expression by the given visitor.

Parameters:

visitor - The ExpressionVisitor to visit this object

addChildrenTo

protected void addChildrenTo(Collection<Expression> children)

Description copied from class: AbstractExpression

Adds the children of this AbstractExpression to the given collection.

Overrides:

addChildrenTo in class AbstractExpression

Parameters:

children - The collection used to store the children

acceptChildren

public void acceptChildren(ExpressionVisitor visitor)

Description copied from interface: Expression

Visits the children of this 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.

Parameters:

visitor - The visitor to visit the children of this object.

addOrderedChildrenTo

protected void addOrderedChildrenTo(List<Expression> children)

Description copied from class: AbstractExpression

Adds the children of this AbstractExpression to the given list.

Overrides:

addOrderedChildrenTo in class AbstractExpression

Parameters:

children - The list used to store the string representation of this AbstractExpression

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 given WordParser.

Specified by:

parse in class AbstractExpression

Parameters:

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

tolerant - 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 in LocalDateTime expression.

Parameters:

dateAction - function executed for LOCAL DATE

timeAction - function executed for LOCAL TIME

dateTimeAction - function executed for LOCAL DATETIME

getValueByType

public <R> R getValueByType(Supplier<R> dateAction,
 Supplier<R> timeAction,
 Supplier<R> dateTimeAction)

Execute supplier depending on local date/time text identifier in LocalDateTime expression.

Parameters:

dateAction - function executed for LOCAL DATE

timeAction - function executed for LOCAL TIME

dateTimeAction - function executed for LOCAL DATETIME

getQueryBNF

public JPQLQueryBNF getQueryBNF()

Description copied from interface: Expression

Returns the BNF of this Expression.

Returns:

The JPQLQueryBNF, which represents the grammar of this Expression

toParsedText

protected void toParsedText(StringBuilder writer,
 boolean actual)

Description copied from class: AbstractExpression

Generates a string representation of this Expression, including its children, if it has any.

Specified by:

toParsedText in class AbstractExpression

Parameters:

writer - The buffer used to append this Expression's string representation

actual - 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 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.

Specified by:

toActualText in interface Expression

Overrides:

toActualText in class AbstractExpression

Returns:

The string representation of this Expression
