    • Method Summary

      All Methods Instance Methods Abstract Methods 
      Modifier and Type Method Description
      boolean add​(byte[] value, T item)
      Adds a byte sequence to the trie, with corresponding user item.
      ByteTrieNodeIfc<T> find​(byte[] value)
      Finds a byte sequence in the trie and returns a node interface object for it, or null if not present.
      void inorder​(TaskMonitor monitor, Op<T> op)
      Visits all the nodes in the trie such that the visitation order is properly byte value ordered.
      boolean isEmpty()
      Returns if the trie is empty.
      int numberOfNodes()
      Returns the number of nodes in the trie; this is essentially equal to the sum of the number of characters in all byte sequences present in the trie, minus their shared prefixes.
      java.util.List<SearchResult<java.lang.Integer,​T>> search​(byte[] text, TaskMonitor monitor)
      Search an array of bytes using the Aho-Corasick multiple string trie search algorithm.
      java.util.List<SearchResult<Address,​T>> search​(Memory memory, AddressSetView view, TaskMonitor monitor)
      Search an array of bytes using the Aho-Corasick multiple string trie search algorithm.
      int size()
      Returns the number of byte sequences in the trie.
    • Method Detail

      • isEmpty

        boolean isEmpty()
        Returns if the trie is empty.
        Returns:
        if the trie is empty
      • size

        int size()
        Returns the number of byte sequences in the trie.
        Returns:
        the number of byte sequences in the trie
      • numberOfNodes

        int numberOfNodes()
        Returns the number of nodes in the trie; this is essentially equal to the sum of the number of characters in all byte sequences present in the trie, minus their shared prefixes.
        Returns:
        the number of nodes in the trie
      • add

        boolean add​(byte[] value,
                    T item)
        Adds a byte sequence to the trie, with corresponding user item. Returns if the add took place, or if this add was essentially a replacement of a previously present value (previous user item is lost forever).
        Parameters:
        value - the byte sequence to insert into the trie
        item - a user item to store in that location
        Returns:
        whether the add took place
      • find

        ByteTrieNodeIfc<T> find​(byte[] value)
        Finds a byte sequence in the trie and returns a node interface object for it, or null if not present.
        Parameters:
        value - the byte sequence sought
        Returns:
        the node interface if present, or null
      • inorder

        void inorder​(TaskMonitor monitor,
                     Op<T> op)
              throws CancelledException
        Visits all the nodes in the trie such that the visitation order is properly byte value ordered. The client is responsible for not performing actions on non-terminal nodes as necessary.
        Parameters:
        monitor - a task monitor
        op - the operation to perform
        Throws:
        CancelledException - if the user cancels
      • search

        java.util.List<SearchResult<java.lang.Integer,​T>> search​(byte[] text,
                                                                       TaskMonitor monitor)
                                                                throws CancelledException
        Search an array of bytes using the Aho-Corasick multiple string trie search algorithm.
        Parameters:
        text - the bytes to search
        Returns:
        a list of results (tuple of offset position, text found)
        Throws:
        CancelledException
