SimpleCondition class

Represents the default condition with {field} {operator} {value} structure.

public abstract class Korzh.EasyQuery.SimpleCondition
    : Condition

Properties

Type	Name	Description
`EqExpression`	BaseExpr	Gets or sets the base expression of the condtion.
`Operand`	DefaultOperand	Gets the default operand.
`SimpleCondExprList`	Expressions	Gets the list of all expressions used in condition. First expression in the list is base expression.
`Operator`	Operator	Gets or sets the operator used in this condition.
`String`	TypeName	Gets the name of the condition type. The same as STypeName but works for one particular instance of SimpleCondition class.

Methods

Type	Name	Description
`void`	AdjustOperator()	Adjusts the operator by base expression.
`void`	AttachExpr(`EqExpression` expr)	Attaches the handler for expression’s OnContentChange event to DoExprContentChanged method
`EqExpression`	CreateValueExpr(`Int32` index)	Creates the value expression.
`EqExpression`	CreateValueExprByOperand(`Operand` opnd)	Creates a value expression by operand.
`void`	DetachExpr(`EqExpression` expr)	Detaches the handler for expression’s OnContentChange event
`void`	DoExprContentChanged(`Object` sender, `EventArgs` e)	Does the expr changed.
`EntityAttr`	GetBaseAttr()	Gets the base entity attribute for this condition.
`Operand`	GetOperand(`Int32` index)	Gets the condition operand based on its index. Index 0 stands for an attribute
`String`	GetText(`QueryTextFormats` formats, `String` levelSpace, `String` prefix)	Returns text representation of condition
`IEnumerable<Entity>`	GetUsedEntities()	Gets the list of all entities used in condition.
`void`	LoadFromJsonDict(`JsonDict` dictCond)	Loads condition from IDictionary. Used during loading query from JSON
`void`	LoadFromXmlReader(`XmlReader` reader)	Loads Korzh.EasyQuery.SimpleCondition properties from XML reader.
`EqExpression`	RecreateValueExpr(`Int32` index)	Recreates the value expression.
`void`	SetOperator(`Operator` newOperator)	Sets the operator.
`void`	SetOperatorSilent(`Operator` newOperator)	Sets the operator in “silent” mode (no event is raised, no expression is adjusted).
`void`	SetValueExpr(`Int32` index, `EqExpression` expr)	Sets the value expression.
`void`	WriteContent(`XmlWriter` writer)	Writes the content of condition to XmlWriter object.
