Usage: (emit-matrix vars clauses)
(emit-matrix vars clauses default)
Take the list of vars and sequence of unprocessed clauses and return the pattern matrix. The pattern matrix contains the processed pattern rows and the list of vars originally specified. Inserts a last match - :else if provided by the user or a default match that throws.Source
No usage documentation available
Returns the corresponding pattern for the given syntax. Dispatches on the class of its argument. For example, `[(:or 1 2) 2]` is dispatched as clojure.lang.IPersistentVectorSource
No usage documentation available
Handles patterns wrapped in the special list syntax. Dispatches on the first or second keyword in the list. For example, the pattern `(:or 1 ...) is dispatches as :or, and `(1 :as a)` is dispatched by :as.Source
Usage: (empty-rows-case)
Case 1: If there are no pattern rows to match, then matching always failsSource
Usage: (first-column-chosen-case matrix col ocrs)
Case 3a: The first column is chosen. Compute and return a switch/bind node with a default matrix caseSource
Usage: (first-row-empty-case rows ocr)
Case 2: If the first row is empty then matching always succeeds and yields the first action.Source
Usage: (first-row-wildcards-case rows ocrs)
Case 2: If the first row is constituted by wildcards then matching matching always succeeds and yields the first action.Source
Usage: (group-keywords pattern)
Returns a pattern with pattern-keywords (:when and :as) properly grouped. The original pattern may use the 'flattened' syntax. For example, a 'flattened' pattern row like [a b :when even?] is grouped as [a (b :when even?)].Source
No usage documentation available
Determine if two patterns may be grouped together for simultaneous testing.Source

Usage: (map->SwitchNode m#)
Factory function for class clojure.core.match.SwitchNode, taking a map of keywords to field values.Source
Usage: (match vars & clauses)
Pattern match a row of occurrences. Take a vector of occurrences, vars.
Clause question-answer syntax is like `cond`. Questions must be
wrapped in a vector, with same arity as vars. Last question can be :else,
which expands to a row of wildcards. Optionally may take a single
var not wrapped in a vector, questions then need not be wrapped in a
vector.
Example:
(let [x 1
y 2]
(match [x y 3]
[1 2 3] :answer1
:else :default-answer))
Source
Usage: (matchm vars & clauses)
Same as match but supports IMatchLookup when matching maps.Source
Usage: (other-column-chosen-case matrix col)
Case 3b: A column other than the first is chosen. Swap column col with the first column and compile the resultSource
Usage: (process-vars vars)
Process the vars for the pattern matrix. If user provides an expression, create a var and annotate via metadata with the original expression.Source
Usage: (to-pattern-row pat action)
Take an unprocessed pattern expression and an action expression and return a pattern row of the processed pattern expression plus the action epxression.Source
No usage documentation available
Returns a Clojure form that, when executed, is truthy if the pattern matches the occurrence. Dispatches on the `type` of the pattern. For instance, a literal pattern might return `(= ~(:pattern pattern) ~ocr)`, using `=` to test for a match.Source
Usage: (wildcards-and-duplicates patterns)
Returns a vector of two elements: the set of all wildcards and the set of duplicate wildcards. The underbar _ is excluded from both.Source
Usage: (bean-match class)
Generate an implementation of match.core/IMatchLookup for a Java bean. Accessor method names are mapped to keys like this: isVisible -> :visible? getText -> :text getAbsolutePath -> :absolute-path isFUD -> :fud? getFUDFactor -> :fud-factorSource
Allows arbitrary objects to act like a map-like object when pattern matched. Avoid extending this directly for Java Beans, see `match.java/bean-match`.Known implementations: clojure.lang.ILookup, java.util.Date
