                                    Term term)

Creates a new TermSlice with the specified boundary.

Parameters:

bound - the boundary type

include - true if the boundary is inclusive

term - the value

Returns:

a new TermSlice instance

bound

public Term bound(Bound bound)

Returns the boundary value.

Parameters:

bound - the boundary type

Returns:

the boundary value

hasBound

public boolean hasBound(Bound b)

Checks if this slice has a boundary for the specified type.

Parameters:

b - the boundary type

Returns:

true if this slice has a boundary for the specified type, false otherwise.

isInclusive

public boolean isInclusive(Bound b)

Checks if this slice boundary is inclusive for the specified type.

Parameters:

b - the boundary type

Returns:

true if this slice boundary is inclusive for the specified type, false otherwise.

merge

Parameters:

otherSlice - the slice to merge to

Returns:

the new slice resulting from the merge

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getIndexOperator

public Operator getIndexOperator(Bound b)

Returns the index operator corresponding to the specified boundary.

Parameters:

b - the boundary type
