Parameters:

declaration - The Declaration which specifies the Pattern

Returns:

The FactHandle

getFactHandles

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(LeftTuple other)

We use this equals method to avoid the cast

Parameters:

tuple -

Returns:

equals

public boolean equals(Object object)

Overrides:

equals in class Object

size

public int size()

Description copied from interface: Tuple

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

Specified by:

size in interface Tuple

Returns:

getSubTuple

public LeftTuple 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;
