Assembly:
ActiproSoftware.Text.WinForms.dll

Provides the base requirements for a lexical scope.

Indicates whether ancestor end scope checking is enabled while parsing inside the scope.

bool IsAncestorEndScopeCheckEnabled { get; }

Remarks

When enabled, this allows ancestor scopes to be examined to see a pattern matches their end scope. In the event a match is found, this scope exits as well as the ancestor's scope.

LexicalState

The ILexicalState that defines the lexical scope.

ILexicalState? LexicalState { get; }

Property Value

ILexicalState

ParentTransition

ILexicalStateTransition? ParentTransition { get; }

Property Value

Remarks

The state transition may be made to a child language.
