Getting the parent node based on the current cursor position:

• findParentNode(predicate: fn(node: ProseMirrorNode) → boolean) → fn(selection: Selection) → ?{pos: number, node: ProseMirrorNode}
  Iterates over parent nodes, returning the first node and its position predicate returns truthy for.

• findParentDomRef(predicate: fn(node: ProseMirrorNode) → boolean, domAtPos: fn(pos: number) → {node: HTMLElement, offset: number}) → fn(selection: Selection) → ?HTMLElement
  Iterates over parent nodes, returning DOM reference of the first node predicate returns truthy for.

• hasParentNode(predicate: fn(node: ProseMirrorNode) → boolean) → fn(selection: Selection) → boolean
  Checks if there's a parent node predicate returns truthy for.

• findParentNodeOfType(nodeType: NodeType) → fn(selection: Selection) → ?{node: ProseMirrorNode, pos: number}
  Iterates over parent nodes, returning first node of the given nodeType.

• hasParentNodeOfType(nodeType: NodeType) → fn(selection: Selection) → boolean
  Checks if there's a parent node of the given nodeType.

• findParentDomRefOfType(nodeType: NodeType, domAtPos: fn(pos: number) → {node: HTMLElement, offset: number}) → fn(selection: Selection) → ?HTMLElement
  Iterates over parent nodes, returning DOM reference of the first node of the given nodeType.

Getting descendants of a given node:

• flatten(node: ProseMirrorNode, descend: ?boolean = true) → [{node: ProseMirrorNode, pos: number}]
  Flattens descendants of a given node. Doesn't descend into a node when descend argument is false. Defaults to true.

• findChildren(node: ProseMirrorNode, predicate: fn(node: ProseMirrorNode) → boolean, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Iterates over descendants of a given node, returning child nodes predicate returns truthy for. Doesn't descend into a node when descend argument is false.

• findTextNodes(node: ProseMirrorNode, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Returns text nodes of a given node. Doesn't descend into a node when descend argument is false.

• findInlineNodes(node: ProseMirrorNode, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Returns inline nodes of a given node. Doesn't descend into a node when descend argument is false.

• findBlockNodes(node: ProseMirrorNode, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Returns block descendants of a given node. Doesn't descend into a node when descend argument is false.

• findChildrenByAttr(node: ProseMirrorNode, predicate: fn(attrs: ?Object) → boolean, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Iterates over descendants of a given node, returning child nodes predicate returns truthy for. Doesn't descend into a node when descend argument is false.

• findChildrenByType(node: ProseMirrorNode, nodeType: NodeType, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Iterates over descendants of a given node, returning child nodes of a given nodeType. Doesn't descend into a node when descend argument is false.

• findChildrenByMark(node: ProseMirrorNode, markType: markType, descend: ?boolean) → [{node: ProseMirrorNode, pos: number}]
  Iterates over descendants of a given node, returning child nodes that have a mark of a given markType. Doesn't descend into a node when descend argument is false. exapmle: findChildrenByMark(paragraph, schema.marks.strong)

• contains(node: ProseMirrorNode, nodeType: NodeType) → boolean
  Returns true if a given node contains nodes of a given nodeType

Tables helpers:

• findTable(selection: Selection) → ?{pos: number, node: ProseMirrorNode}
  Iterates over parent nodes, returning the first found table node.

• isCellSelection(selection: Selection) → boolean
  Checks if current selection is a CellSelection

• isColumnSelected(columnIndex: number) → fn(selection: Selection) → boolean
  Checks if entire column at index columnIndex is selected

• isRowSelected(rowIndex: number) → fn(selection: Selection) → boolean
  Checks if entire row at index rowIndex is selected

• isTableSelected(selection: Selection) → boolean
  Checks if entire table is selected

• getCellsInColumn(columnIndex: number) → fn(selection: Selection) → [{pos: number, node: ProseMirrorNode}]
  Returns an array of cells in a column at index columnIndex.

• getCellsInRow(rowIndex: number) → fn(selection: Selection) → [{pos: number, node: ProseMirrorNode}]
  Returns an array of cells in a row at index rowIndex.

• getCellsInTable(selection: Selection) → [{pos: number, node: ProseMirrorNode}]
  Returns an array of all cells in a table.

Transforms:

• removeParentNodeOfType(nodeType: NodeType) → fn(tr: Transaction) → ?Transaction
  Returns a replace transaction that replaces a node of a given nodeType with the given node.

• replaceParentNodeOfType(nodeType: NodeType, node: ProseMirrorNode) → fn(tr: Transaction) → ?Transaction
  Returns a replace transaction that replaces parent node of a given nodeType with the given node.

• removeSelectedNode(tr: Transaction) → ?Transaction
  Returns a delete transaction that removes selected node.

• safeInsert(node: ProseMirrorNode) → fn(tr: Transaction) → ?Transaction
  Returns an insert transaction that inserts a given node at the current cursor position if it is allowed by schema. If schema restricts such nesting, it will try to find the appropriate place for the given node in the document, looping through parent nodes up until the root document node.
