Interface Tuple

    • Method Detail

      • getObject

        java.lang.Object getObject​(int pattern)

      • getObject

        java.lang.Object getObject​(Declaration declaration)

      • toObjects

        default java.lang.Object[] toObjects()

      • toObjects

        java.lang.Object[] toObjects​(boolean reverse)

      • get

        InternalFactHandle get​(int pattern)
        Returns the FactHandle for the given pattern index. If the pattern is empty It returns null.
        Parameters:
        pattern - The index of the pattern from which the FactHandleImpl is to be returned
        Returns:
        The FactHandle

      • getTuple

        Tuple getTuple​(int index)
        Returns the tuple at the given index
        Parameters:
        index -
        Returns:

      • get

        InternalFactHandle get​(Declaration declaration)
        Returns the FactHandle for the given Declaration, which in turn specifcy the Pattern that they depend on.
        Parameters:
        declaration - The Declaration which specifies the Pattern
        Returns:
        The FactHandle

      • toFactHandles

        InternalFactHandle[] toFactHandles()
        Returns the fact handles in reverse order

      • size

        int size()
        Returns the size of this tuple in number of elements (patterns)

      • getIndex

        int getIndex()

      • getParent

        Tuple getParent()

      • getSubTuple

        Tuple getSubTuple​(int elements)
        Returns the ReteTuple that contains the "elements" first elements in this tuple.

        Use carefully as no cloning is made during this process.

        This method is used by TupleStartEqualsConstraint when joining a subnetwork tuple into the main network tuple;

        Parameters:
        elements - the number of elements to return, starting from the begining of the tuple
        Returns:
        a ReteTuple containing the "elements" first elements of this tuple or null if "elements" is greater than size;
