Constructor Details

LocalExpression

public LocalExpression(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

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.

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

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

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

getDateType

public Expression getDateType()

Returns the Expression representing the expression with date type.

Returns:

The expression representing the expression with date type

hasDateType

public boolean hasDateType()

Determines whether the expression with date type was parsed.

Returns:

true if the expression with date type was parsed; false if it was not parsed
