Initializes an instance of the class.

public TokenSet(TextRange textRange, IEnumerable<IToken>? tokens, object? parseContext)
Parameter Type Description
textRange TextRange

The TextRange for which tokens in this set are available.
tokens IEnumerable<IToken>

The enumerable collection of tokens to add to the set.
parseContext object

An optional object that may be used to help provide context information when resuming incremental parsing near the end of this token set.

TokenSet(TextRange, IEnumerable<TagSnapshotRange<ITokenTag>>?, object?)

Initializes an instance of the class.

public TokenSet(TextRange textRange, IEnumerable<TagSnapshotRange<ITokenTag>>? tagRanges, object? parseContext)
Parameter Type Description
textRange TextRange

The TextRange for which tokens in this set are available.
tagRanges IEnumerable<TagSnapshotRange<ITokenTag>>

The enumerable collection of token tag ranges to add to the set.
parseContext object

An optional object that may be used to help provide context information when resuming incremental parsing near the end of this token set.
