AggrFuncExpr class

Represents an expression which is a result of applying some functions to other expressions

public abstract class Korzh.EasyQuery.AggrFuncExpr
    : EqExpression

Type	Name	Description
`Boolean`	distinct	Indicates whether all entries of the result must be different
`AggrFunction`	function	The function of Korzh.EasyQuery.AggrFuncExpr

Type	Name	Description
`EqExpression`	Argument	Gets or sets the main argument.
`String`	CustomFunc	Gets the custom func for expression if defined
`DataType`	DataType	Gets or sets the data type.
`Boolean`	Distinct	Gets or sets a value indicating whether this `AggrFuncExpr` has “DISTINCT” attribute.
`AggrFunction`	Function	Gets or sets the function.
`String`	Text	Gets the expression text.
`String`	Value	Gets or sets the expression value.

Type	Name	Description
`void`	AssignExpr(`EqExpression` expr)	Assigns some expression to this one. For AggrFuncExpr class this method assigns the Expression object passed in parameter to Argument property
`void`	AttachArgument(`EqExpression` argument)
`void`	DetachArgument(`EqExpression` argument)
`void`	LoadFromJsonDict(`JsonDict` dict)	Loads expression from IDictionary object (used when we load query from JSON).
`void`	LoadFromXmlReader(`XmlReader` reader)	Loads expression from XML.
`void`	SaveToJsonDictCore(`JsonDict` dict)	Saves expression’s properties to dictionary (used to serialize expression into JSON) This is an abstract method which should be overridden in descendant classes.
`void`	SaveToXmlWriter(`XmlWriter` writer, `String` tagName)	Saves expression to XML writer.
`void`	SetContentSilent(`String` val, `String` txt)	Sets the content of the expression silently (without calling ContentChanged event).
