  • Class
    Description
    AllVariable
    The All expression is used to collect all the instances of a specified entity type.
    Arithmetic
    This class contains an arithmetic expression that results in a numeric value.
    Condition
    This class contains a condition expression which will always evaluate to a boolean.
    Constant
    The const expression is used to hold a constant value.
    Conversion
    The conversion expression is used to change the result data type of an expression.
    DimensionChange
    The dimension expression is used to change the dimension of the wrapped expression's result.
    ErrorNode
    This semantic node is used to indicate a fatal error in the semantics step.
    ExpressionList
    The list expression combines the result of multiple expressions into a single list.
    FieldVariable
    The field expression retrieves the value of a field from the instance returned by the parent expression.
    FunctionCall
    The function expression can be used to invoke a (custom) function.
    InstanceOf
    This node represents an instance of expression that can be used to check if an instance is of a specified type.
    Inversion
    The InverseExpression class will wrap an expression, and invert its's sign.
    IVariable
    Interface for semantic nodes that are variables.
    ListArithmetic
    The list arithmetic expression performs an operation on two expressions.
    ListCondition
    The list expression resulting in a boolean by comparing expressions resulting in multiple values.
    LocalVariable
    This class holds the information for a local variable.
    LogicalConnective
    The logical expression combines the result of two boolean expressions.
    NamedVariable
    A named expression is used to select a single (static) instance by name.
    Not
    This node is used to invert a boolean expression.
    Predicate
    Predicate expression node (each, exists, isactive) that evaluates to a boolean.
    Root
    This class represents the root of the expression tree.
    Select
    The select expression can be used to retrieve one or more values that match the specified condition.
    TemplateCall
    The template expression is used to include a predefined expression (template) into the current expression.
    TypeOf
    This node represents an instance of expression that can be used to determine the type of an instance.
    Unknown
    This expression is used for unknown nodes (?).
    Variable
    A variable expression is an expression that usually identifies an active instance of an entity type.
