String Query Operations

FluentQuery supports the following operations when querying strings from a container (eg, a TStrings, or a TList<Strings>):

Operation	Bound	Unbound	Terminating	Description
Contains	Yes	Yes		Enumerates string that contain the supplied string.
EndsWith	Yes	Yes		Enumerates strings that end with the supplied string.
Equals	Yes	Yes		Enumerates strings that are exact, case-sensitive matches to the supplied string.
First	Yes	Yes		Enumerate the first string, ignoring the remainder.
From		Yes		From allows you to specify the source of the data you are querying. It is also From which transforms an Unbound Query into a Bound Query.
Matches	Yes	Yes		Enumerates strings that match the supplied string.
NotEquals	Yes	Yes		Enumerates strings that are not exact, case-sensitive matches to the supplied string.
Predicate		Yes	Yes	Returns a TPredicate<String> encapsulating the supplied Unbound Query logic.
Skip	Yes	Yes		Skip will bypass the specified number of strings from the start of the enumeration, after which it will enumerate the remaining strings as normal.
SkipWhile(Predicate)	Yes	Yes		SkipWhile will bypass strings at the start of the enumeration while the supplied Predicate evaluates True. Once the Predicate evaluates false, all remaining strings will be enumerated as normal.
SkipWhile(UnboundQuery)	Yes	Yes		SkipWhile will bypass strings at the start of the enumeration that match the supplied Unbound Query. Once a string does not match the supplied query, all remaining strings will be enumerated as normal.
StartsWith	Yes	Yes		Enumerates strings that start with the supplied string.
Substring	Yes	Yes		Enumerates each string, returning a substring given a StartingIndex and an optional Length. Subsequent query operations will only enumerate the substring, not the original string.
Take	Yes	Yes		Take will enumerate up to the specified number of strings, then ignore the remainder.
TakeWhile(Predicate)	Yes	Yes		TakeWhile will continue enumerating strings while the supplied Predicate evaluates True, after which it will ignore the remaining strings.
TakeWhile(UnboundQuery)	Yes	Yes		TakeWhile will continue enumerating strings while they match the supplied Unbound Query, after which it will ignore the remaining strings.
ToTStrings	Yes		Yes	Returns a TStrings object containing the Strings that match the query
Value	Yes	Yes		Enumerates Name=Value strings, returning the Value portion for the supplied name.
Where(Predicate)	Yes	Yes		Filter the strings enumerated to only those that evaluate true when passed into the supplied Predicate
WhereNot(Predicate)	Yes	Yes		Filter the strings enumerated to only those that evaluate false when passed into the supplied Predicate
WhereNot(UnboundQuery)	Yes	Yes		Filter the strings enumerated to only those that do not match the supplied Unbound Query

Note, unless otherwise stated, all String Query Operations can be either case-sensitive or case-insensitive, but are case-insensitive by default.
