Description

Text range is a group of consecutive tokens. Text ranges may intersect each other.

Text ranges are created by the block rule (TTagBlockCondition, BlockType is btRangeStart), that is stored in Rule property.

After creating text range properties StartIdx, IdentIdx, Parent, Level are determined.

Initially text range is opened (EndIdx is equal to -1). Text range is closed when block rule (TTagBlockCondition, BlockType is btRangeEnd) is succesfully tested and it is referred by the Rule.BlockEnd or BlockEnd property of the block rule is equal to Rule of this text range.

StartIdx is the index of the first token, EndIdx is the index of the last token.

To access text ranges array use TClientSyntAnalyzer.Ranges property.

Parent specifies parent text range (last opened text range when current text range is being created), Level is the indentation in the ranges tree.

Notes

Parent text range is always before children. You can use this to optimize tree filling.
