Uses of AbstractSingleEncapsulatedExpression in org.eclipse.persistence.jpa.jpql.parser

Subclasses of AbstractSingleEncapsulatedExpression in org.eclipse.persistence.jpa.jpql.parser

Modifier and Type	Class and Description
class	AbsExpression The ABS function removes the minus sign from a specified argument and returns the absolute value, which is always a positive number or zero.
class	AggregateFunction In the SELECT clause the result of a query may be the result of an aggregate function applied to a path expression.
class	AllOrAnyExpression An ALL conditional expression is a predicate that is true if the comparison operation is true for all values in the result of the subquery or the result of the subquery is empty.
class	AvgFunction One of the aggregate functions.
class	CastExpression The CAST function cast value to a different type.
class	CoalesceExpression A COALESCE expression returns null if all its arguments evaluate to null, and the value of the first non-null argument otherwise.
class	ConcatExpression The CONCAT function returns a string that is a concatenation of its arguments.
class	CountFunction One of the aggregate functions.
class	EncapsulatedIdentificationVariableExpression This Expression represents an identification variable that maps a Map property, either the key, the value or a Map.Entry).
class	EntryExpression An identification variable qualified by the ENTRY operator is a path expression.
class	ExistsExpression An EXISTS expression is a predicate that is true only if the result of the subquery consists of one or more values and that is false otherwise.
class	ExtractExpression The EXTRACT function extracts a date part from a date/time value.
class	FunctionExpression This expression adds support to call native database functions.
class	IndexExpression The INDEX function returns an integer value corresponding to the position of its argument in an ordered list.
class	KeyExpression An identification variable qualified by the KEY operator is a path expression.
class	LengthExpression The LENGTH function returns the length of the string in characters as an integer.
class	LowerExpression The LOWER function converts a string to lower case and it returns a string.
class	MaxFunction One of the aggregate functions.
class	MinFunction One of the aggregate functions.
class	ObjectExpression Stand-alone identification variables in the SELECT clause may optionally be qualified by the OBJECT operator.
class	SizeExpression The SIZE function returns an integer value, the number of elements of the collection.
class	SqrtExpression The SQRT function takes a numeric argument and returns a double.
class	SubExpression This expression wraps a sub-expression within parenthesis.
class	SumFunction One of the aggregate functions.
class	TableExpression Defines a table expression.
class	TrimExpression The TRIM function trims the specified character from a string.
class	TypeExpression An entity type expression can be used to restrict query polymorphism.
class	UpperExpression The UPPER function converts a string to upper case and it returns a string.
class	ValueExpression An identification variable qualified by the VALUE operator is a path expression.
