Method Detail

contains

public abstract boolean contains(XSType type)

Return true if this TypeSet contains the specified type. Concrete implementations of this method determine what it means for the TypeSet to "contain" a type.

Parameters:

type - the type

Returns:

true iff this TypeSet contains the specified type

intersection

public static TypeSet intersection(TypeSet a,
                                   TypeSet b)

Calculate the TypeSet formed by the intersection of two other TypeSet objects.

Parameters:

a - a TypeSet

b - another TypeSet

Returns:

the intersection of a and b

union

public static TypeSet union(TypeSet a,
                            TypeSet b)

Calculate the TypeSet formed by the union of two other TypeSet objects.

Parameters:

a - a TypeSet

b - another TypeSet

Returns:

the union of a and b
