类 WildcardManager

java.lang.Object
proguard.util.WildcardManager
public class WildcardManager extends Object
This utility class creates and manages StringMatcher instances that (1) match wildcards, and (2) refer back to matched wildcards.

Each instance represents a scope in which wildcards can be specified and referenced.

  • 构造器详细资料

    • WildcardManager

      public WildcardManager()
      Creates a new WildcardManager.

    • WildcardManager

      public WildcardManager(WildcardManager wildcardManager)
      Creates a new WildcardManager with the current list of string matchers of the given WildcardManager.

  • 方法详细资料

    • reset

      public void reset()
      Resets the list of string matchers.

    • createVariableStringMatcher

      public VariableStringMatcher createVariableStringMatcher(char[] allowedCharacters, char[] disallowedCharacters, int minimumLength, int maximumLength, StringMatcher nextMatcher)
      Creates a new VariableStringMatcher and remembers it as a next element in the list of string matchers, so it can be referenced by its index later.
      参数:
      allowedCharacters - an optional list of allowed characters.
      disallowedCharacters - an optional list of disallowed characters.
      minimumLength - the minimum length of te variable string.
      maximumLength - the maximum length of te variable string.
      nextMatcher - an optional next matcher for the remainder of the string.

    • rememberVariableStringMatcher

      public void rememberVariableStringMatcher(VariableStringMatcher variableStringMatcher)
      Remembers the given VariableStringMatcher as a next element in the list of string matchers, so it can be referenced by its index later.

    • createMatchedStringMatcher

      public MatchedStringMatcher createMatchedStringMatcher(int index, StringMatcher nextMatcher)
      Creates new MatchedStringMatcher to match the the specified variable string matcher from the list of string matchers.
      参数:
      index - the 0-based index of previously created and remembered VariableStringMatcher instances.
      nextMatcher - an optional next matcher for the remainder of the string.

    • createMatchedStringFunction

      public StringFunction createMatchedStringFunction(String expression)
      Creates new StringFunction that transforms the given expression with possible references to wildcards, based on the list of string matchers.

      For example: "foo<1>" returns a string function that prepends "foo" to the first wildcard of the recently matched string.

    • wildCardIndex

      public int wildCardIndex(String regularExpression, int index) throws IllegalArgumentException
      Parses a reference to a wildcard at a given index, if any.

      For example: "foo<1>" at index 0 returns -1, "foo<1>" at index 3 returns 0. "foo<8>" at index 3 returns 7.

      参数:
      regularExpression - the regular expression.
      index - the index at which the regular expression is to be checked for a reference.
      返回:
      the 0-based index of the back reference, or -1 otherwise.
      抛出:
      IllegalArgumentException - if the reference is malformed.
