- Mixed in types
Constructors
Properties
- characterSimilarity → double
-
Returns the similarity between the collection of letters of term and
other on a scale of 0.0 to 1.0.
read-only, inherited
- editDistance → int
-
Returns the
Damerau–Levenshtein distance, the minimum number of single-character edits (transpositions, insertions, deletions or substitutions) required to change term into other.read-only, inherited - editSimilarity → double
-
A normalized measure of editDistance on a scale of 0.0 to 1.0.
read-only, inherited
- hashCode → int
-
The hash code for this object.
read-only, inherited
- jaccardSimilarity → double
-
Returns the Jaccard Similarity Index between term and other.
read-only, inherited
- lengthDistance → int
-
Returns the absolute value of the difference in length between term
and other.
read-only, inherited
- lengthSimilarity → double
-
Returns the similarity in length between two terms, defined as:
lengthSimilarity = 1 minus the log of the ratio between the term lengths,
with a floor at 0.0:
1-(log(this.length/other.length))read-only, inherited - other → Term
-
The term that is being compared to term.
read-only, inherited
- runtimeType → Type
-
A representation of the runtime type of the object.
read-only, inherited
- similarity → double
-
The compound similarity value on a scale of 0.0 to 1.0.
read-only, inherited
- startsWithSimilarity → double
-
Compares the starting charcters of the String with that of other,
limiting the comparison to a substring of this or other that is
the shorter of this.length or other.length. ///
read-only, inherited
- term → Term
-
The term that is being compared to other.
read-only, inherited
Methods
-
compareTo(
TermSimilarity other) → int -
Compares this to other, alphabetically, non-case sensitive.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> -
Serializes the TermSimilarity to
Map<String, dynamic>.inherited -
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
Returns true if runtimeType, term and similarity are equal.
