Syntax

public sealed class CharSequenceMatcher : ValueMatcher

Remarks

Sequences are matched in both directions along each line of characters, and keyboard sequences are also matched with the shift key held. A sequence must be at least MinSequenceLength characters long. The longest sequence is matched first.

Constructors

Name	Description
CharSequenceMatcher(CharSequenceTypes, bool)	Initializes a new instance of the CharSequenceMatcher class.

Fields

Name	Description
Alphabet	The letters of the alphabet, in order.
MinSequenceLength	The minimum number of characters in a sequence.

Properties

Name	Description
SequenceTypes	Gets the types of sequences that are matched.

Methods

Name	Description
GetValueMatches(PasswordMatchContext)	Gets the contexts that result from matching the value at the current position of the given context, in the order they should be tried. Repeats and trailing separators do not need to be handled by the implementation.
