Methods

computeSelection({required NodePosition base, required NodePosition extent}) → UpstreamDownstreamNodeSelection
Returns a node-specific representation of a selection from base to extent.
override
containsPosition(Object position) → bool
Returns true if this DocumentNode contains the given position, or false if the position doesn't sit within this node, or if the position type doesn't apply to this DocumentNode.
override
copyAndReplaceMetadata(Map<String, dynamic> newMetadata) → DocumentNode
Returns a copy of this DocumentNode, replacing its existing metadata with newMetadata.
inherited
copyContent(NodeSelection selection) → String?
Returns a plain-text version of the content in this node within selection, or null if the given selection does not make sense as plain-text.
inherited
copyMetadata() → Map<String, dynamic>
Returns a copy of this node's metadata.
inherited
copyWithAddedMetadata(Map<String, dynamic> newProperties) → DocumentNode
Returns a copy of this DocumentNode with newProperties added to the node's metadata.
inherited
getAffinityBetween({required NodePosition base, required NodePosition extent}) → TextAffinity

Available on DocumentNode, provided by the InspectNodeAffinity extension

Returns the affinity direction implied by the given base and extent.
getMetadataValue(String key) → dynamic
Returns this node's metadata value for the given key.
inherited
hasEquivalentContent(DocumentNode other) → bool
Returns true if the other node is the same type as this node, and contains the same content.
inherited
hasMetadataValue(String key) → bool
Returns true if this node has a non-null metadata value for the given metadata key, and returns false, otherwise.
inherited
initAddToMetadata(Map<String, dynamic> addedMetadata) → void
Adds addedMetadata to this nodes metadata.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
selectDownstreamPosition(NodePosition position1, NodePosition position2) → UpstreamDownstreamNodePosition
Inspects position1 and position2 and returns the one that's positioned further downstream in this DocumentNode.
override
selectUpstreamPosition(NodePosition position1, NodePosition position2) → UpstreamDownstreamNodePosition
Inspects position1 and position2 and returns the one that's positioned further upstream in this DocumentNode.
override
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
