Predefined variables

The FlexiLayout language provides the following predefined variables. Their values report whether a block was found or detected reliably and define the region of a found block.

Region Expression variables

Each row lists a variable and how it is used in the Region Expression section.

Name	Description
`IsNull`	Variable of type `Logic`. Used in the Region Expression section. The value of the variable determines whether the block has been found. The `IsNull` variable is pre-initialized with the value False, which means that the block has been found. To tell FlexiLayout Studio that the block has not been found, set the `IsNull` variable to True. Used for blocks of all types.
`IsSuspicious`	A variable of type `Logic` used in the Region Expression section. Its value indicates whether the block has been detected reliably. The `IsSuspicious` variable is pre-initialized with the value False, which means that the block has been detected. To tell FlexiLayout Studio that the block has been detected unreliably, set the value of the `IsSuspicious` variable to True. Used for blocks of all types.
`OutputInstances`	Variable used in the Region Expression section for blocks of all types for which Has repeating instances is enabled. For non-table blocks, the type of the variable is `HypothesisInstances`. For table blocks, the type of the variable is `TableHypothesisInstances`. The value of the variable defines the detected region of the block. The region of a block built from the instances of the elements and subelements of a repeating group is discontinuous.
`OutputRegion`	Variable of type `Region`. Used in the Region Expression section. The value of the variable determines the region of the block. Used for blocks of all types except table blocks.
`OutputTable`	Variable of type `TableHypothesis`. Used in the Region Expression section. The value of the variable is used to initialize the region and the contents of a block on the basis of a specific table element. Used only for table blocks.
