Method Detail

difference

public SimpleSelectorSequence difference(SimpleSelectorSequence that)

Returns this \ that, set-theoretically

union

public SimpleSelectorSequence union(SimpleSelectorSequence that)

Returns this followed by all elements in that but not in this

unify

public SimpleSelectorSequence unify(SimpleSelectorSequence extend,
                                    SimpleSelectorSequence extending)

Tries to unify this with the "extending" simple selector sequence by extend. The simple selector sequence extend is a unifier only if it subsumes (is more general than) this selector. The result is this selector minus simple selectors in extend plus simple selectors in extending. Example: this = a.foo.bar, extend = a.foo, extending = b.baz result = b.bar.baz Note: if extend lacks a type selector, this and extending must share the same type selector.

getTypeSelector

public TypeSelector getTypeSelector()

getNonTypeSelectors

public SimpleSelectorSequence getNonTypeSelectors()

subsumes

public boolean subsumes(SimpleSelectorSequence that)

Returns whether this simple selector sequence matches (at least) all elements that simple selector sequence matches. True if the simple selectors in this is a subset of those in that. If type selector is universal in this, compare other kinds of simple selectors only.

replaceVariable

public SimpleSelectorSequence replaceVariable(VariableNode var)

toString

public String toString()

Overrides:

toString in class AbstractCollection<SimpleSelector>

withoutTypeSelector

public SimpleSelectorSequence withoutTypeSelector()

Returns the same sequence, but without type selector if one was present.

isPlaceholder

public boolean isPlaceholder()

Returns whether this selector contains a placeholder (%-selector)
