.. _`FlowQuery Operation Reference`: FlowQuery Operation Reference ============================= This reference was automatically generated from code on 2019-03-05 .. _`FlowQuery Operation Reference: add`: add --- Adds the given items to the current context. The operation accepts one argument that may be an Array, a FlowQuery or an Object. :Implementation: Neos\\Eel\\FlowQuery\\Operations\\AddOperation :Priority: 1 :Final: No :Returns: void .. _`FlowQuery Operation Reference: cacheLifetime`: cacheLifetime ------------- "cacheLifetime" operation working on ContentRepository nodes. Will get the minimum of all allowed cache lifetimes for the nodes in the current FlowQuery context. This means it will evaluate to the nearest future value of the hiddenBeforeDateTime or hiddenAfterDateTime properties of all nodes in the context. If none are set or all values are in the past it will evaluate to NULL. To include already hidden nodes (with a hiddenBeforeDateTime value in the future) in the result, also invisible nodes have to be included in the context. This can be achieved using the "context" operation before fetching child nodes. Example: q(node).context({'invisibleContentShown': true}).children().cacheLifetime() :Implementation: Neos\\ContentRepository\\Eel\\FlowQueryOperations\\CacheLifetimeOperation :Priority: 1 :Final: Yes :Returns: integer The cache lifetime in seconds or NULL if either no content collection was given or no child node had a "hiddenBeforeDateTime" or "hiddenAfterDateTime" property set .. _`FlowQuery Operation Reference: children`: children -------- "children" operation working on generic objects. It iterates over all context elements and returns the values of the properties given in the filter expression that has to be specified as argument or in a following filter operation. :Implementation: Neos\\Eel\\FlowQuery\\Operations\\Object\\ChildrenOperation :Priority: 1 :Final: No :Returns: void .. _`FlowQuery Operation Reference: children`: children -------- "children" operation working on ContentRepository nodes. It iterates over all context elements and returns all child nodes or only those matching the filter expression specified as optional argument. :Implementation: Neos\\ContentRepository\\Eel\\FlowQueryOperations\\ChildrenOperation :Priority: 100 :Final: No :Returns: void .. _`FlowQuery Operation Reference: closest`: closest ------- "closest" operation working on ContentRepository nodes. For each node in the context, get the first node that matches the selector by testing the node itself and traversing up through its ancestors. :Implementation: Neos\\ContentRepository\\Eel\\FlowQueryOperations\\ClosestOperation :Priority: 100 :Final: No :Returns: void .. _`FlowQuery Operation Reference: context`: context ------- "context" operation working on ContentRepository nodes. Modifies the ContentRepository Context of each node in the current FlowQuery context by the given properties and returns the same nodes by identifier if they can be accessed in the new Context (otherwise they will be skipped). Example: q(node).context({'invisibleContentShown': true}).children() :Implementation: Neos\\ContentRepository\\Eel\\FlowQueryOperations\\ContextOperation :Priority: 1 :Final: No :Returns: void .. _`FlowQuery Operation Reference: count`: count ----- Count the number of elements in the context. If arguments are given, these are used to filter the elements before counting. :Implementation: Neos\\Eel\\FlowQuery\\Operations\\CountOperation :Priority: 1 :Final: Yes :Returns: void|integer with the number of elements .. _`FlowQuery Operation Reference: filter`: filter ------ Filter operation, limiting the set of objects. The filter expression is expected as string argument and used to reduce the context to matching elements by checking each value against the filter. A filter expression is written in Fizzle, a grammar inspired by CSS selectors. It has the form `"[" [] "]"` and supports the following operators: = Strict equality of value and operand != Strict inequality of value and operand < Value is less than operand <= Value is less than or equal to operand > Value is greater than operand >= Value is greater than or equal to operand $= Value ends with operand (string-based) or value's last element is equal to operand (array-based) ^= Value starts with operand (string-based) or value's first element is equal to operand (array-based) *= Value contains operand (string-based) or value contains an element that is equal to operand (array based) instanceof Checks if the value is an instance of the operand !instanceof Checks if the value is not an instance of the operand For the latter the behavior is as follows: if the operand is one of the strings object, array, int(eger), float, double, bool(ean) or string the value is checked for being of the specified type. For any other strings the value is used as classname with the PHP instanceof operation to check if the value matches. :Implementation: Neos\\Eel\\FlowQuery\\Operations\\Object\\FilterOperation :Priority: 1 :Final: No :Returns: void .. _`FlowQuery Operation Reference: filter`: filter ------ This filter implementation contains specific behavior for use on ContentRepository nodes. It will not evaluate any elements that are not instances of the `NodeInterface`. The implementation changes the behavior of the `instanceof` operator to work on node types instead of PHP object types, so that:: [instanceof Neos.NodeTypes:Page] will in fact use `isOfType()` on the `NodeType` of context elements to filter. This filter allow also to filter the current context by a given node. Anything else remains unchanged. :Implementation: Neos\\ContentRepository\\Eel\\FlowQueryOperations\\FilterOperation :Priority: 100 :Final: No :Returns: void .. _`FlowQuery Operation Reference: find`: find ---- "find" operation working on ContentRepository nodes.
