The TextSelectionOperator, simply put, allows comparison of two [TextSelection'] instances. It allows testing for all kinds of spatial relations (as embodied by this enum) in which two [TextSelection`] instances can be.

Rather than operator on single TextSelection instances, te implementation goes a bit further and can act also on the basis of TextSelectionSet rather than TextSelection, allowing you to compare two sets, each containing possibly multiple TextSelections, at once.

Variants

Equals

Fields

all: bool

negate: bool

Both sets occupy cover the exact same TextSelections, and all are covered (cf. textfabric’s ==), commutative, transitive

Overlaps

Fields

all: bool

negate: bool

All items in both sets must cover the exact same TextSelection. This would be fairly useless, it just means both sets contain only one TextSelection and it’s the same one Each TextSelection in A overlaps with a TextSelection in B (cf. textfabric’s &&), commutative If modifier all is set: Each TextSelection in A overlaps with all TextSelection in B (cf. textfabric’s &&), commutative

Embeds

Fields

all: bool

negate: bool

All TextSelections in B are embedded by a TextSelection in A (cf. textfabric’s [[) If modifier all is set: All TextSelections in B are embedded by all TextSelection in A (cf. textfabric’s [[)

Embedded

Fields

all: bool

negate: bool

All TextSelections in A are embedded by a TextSelection in B (cf. textfabric’s ]]) If modifier all is set: All TextSelections in A are embedded by all TextSelection in B (cf. textfabric’s ]])

Precedes

Fields

all: bool

negate: bool

Each TextSelections in A precedes (comes before) a textselection in B If modifier all is set: All TextSelections in A precede (come before) all textselections in B. There is no overlap (cf. textfabric’s <<)

Succeeds

Fields

all: bool

negate: bool

Each TextSeleciton In A succeeds (comes after) a textselection in B If modifier all is set: All TextSelections in A succeed (come after) all textselections in B. There is no overlap (cf. textfabric’s >>)

LeftAdjacent

Fields

all: bool

negate: bool

Each TextSelection in A is ends where at least one TextSelection in B begins. If modifier all is set: The rightmost TextSelections in A end where the leftmost TextSelection in B begins (cf. textfabric’s <:)

RightAdjacent

Fields

all: bool

negate: bool

Each TextSelection in A is begis where at least one TextSelection in A ends. If modifier all is set: The leftmost TextSelection in A starts where the rightmost TextSelection in B ends (cf. textfabric’s :>)

SameBegin

Fields

all: bool

negate: bool

Each TextSelection in A starts where a TextSelection in B starts If modifier all is set: The leftmost TextSelection in A starts where the leftmost TextSelection in B start (cf. textfabric’s =:)

SameEnd

Fields

all: bool

negate: bool

Each TextSelection in A ends where a TextSelection in B ends If modifier all is set: The rightmost TextSelection in A ends where the rights TextSelection in B ends (cf. textfabric’s :=)

InSet

Fields

all: bool

negate: bool

Each TextSelection in A is in B as well, this is similar to Equals but allows for set B having unmatched items

SameRange

Fields

all: bool

negate: bool

The leftmost TextSelection in A starts where the leftmost TextSelection in A starts and the rightmost TextSelection in A ends where the rights TextSelection in B ends (cf. textfabric’s ::)
