SearchNode

public SearchNode(@NonNull Node childNode)

Create a SearchNode representing the query function `search(queryString)`.

By default, the query function search will have an empty list of restricts. The search function will return all results from the query.

public SearchNode(@NonNull Node childNode, @NonNull List<PropertyPath> properties)

Create a SearchNode representing the query function `search(queryString, createList(listOfProperties)`.

public void addProperty(@NonNull PropertyPath propertyPath)

Add a restrict to the end of the current list of restricts mProperties.

public @NonNull Node getChild()

Returns the child query searched for in the function.

public @NonNull List<Node> getChildren()

Returns the child Node of SearchNode as a list containing the only child Node.

public @NonNull String getFunctionName()

Returns the name of the function represented by SearchNode.

public @NonNull List<PropertyPath> getProperties()

Returns the list of property restricts applied to the query. If the list is empty, there are no property restricts, which means that `search` will return all results from the query.

public void setChild(@NonNull Node childNode)

Sets the query searched for in the function.

public void setProperties(@NonNull List<PropertyPath> properties)

Sets what property restricts will be applied to the query.

public @NonNull String toString()

Get the query string representation of SearchNode.

If there are no property restricts, then the string representation is the function name followed by the string representation of the child subquery as a string literal, surrounded by parentheses. For example the node represented by

TextNode node = new TextNode("foo");
SearchNode searchNode = new SearchNode(node);

If there are property restricts, i.e. getProperties is not empty, then in addition to the string representation of the child subquery, the property restricts will be represented as inputs to the createList function, which itself will be an input. So for the node represented by

List<PropertyPath> propertyPaths = List.of(new PropertyPath("example.path"),
                                           new PropertyPath("anotherPath"));
TextNode node = new TextNode("foo");
SearchNode searchNode = new SearchNode(node, propertyPaths);

Operators in the query string are supported. As such additional escaping are applied to ensure that operators stay scoped to the search node. This applies recursively, so if we had three layers of search i.e. a search function that takes a query containing a nested search, we would apply three levels of escaping. So for the node represented by

TextNode node = new TextNode("foo");
node.setVerbatim(true);
SearchNode nestedSearchNode = new SearchNode(node);
SearchNode searchNode = new SearchNode(nestedSearchNode);
