All Known Subinterfaces:`Path.Impl`

public interface Path

A Path defines how to navigate to target values in a data structure as a series of steps.
Paths are the core construct for querying and updating PStates. The Path API uses the
builder pattern to specify a series of navigation steps.

Example: `Path.key("a").nth(2)` navigates first to the value for the key `"a"`
in a map, then to the value at the index `2` in a list.

Parameters with "arg" in the name can be a var, value, or [`Expr`](/content/javadoc/com/rpl/rama/Expr.html "class in com.rpl.rama"/index.html).

Pseudocode examples in the Javadoc for each method on this class use JSON-like syntax for
data structures. `select` in these examples produces a list of navigated values, so if
an example `select` navigates to one value the result will be a list of one element.

Transform paths determine what diffs [proxies](/content/docs/~/pstates.html#_reactive_queries/index.html) on those PStates will see.
Each navigator's Javadoc specifies what diffs they produce.

- ## Method Details

- ### create )

static[Path.Impl](/content/javadoc/com/rpl/rama/Path.Impl.html "interface in com.rpl.rama"/index.html)create()

Creates an empty Path. `Path.key("a")` is the same as `Path.create().key("a")`

- ### all )

static[Path.Impl](/content/javadoc/com/rpl/rama/Path.Impl.html "interface in com.rpl.rama"/index.html)all()

Navigates to every element of a collection. Works on lists, maps, and sets. For maps
    navigates to key/value pair with [`List`](https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/util/List.html "class or interface in java.util") interface. Value navigator.

Pseudocode example: `select({"a": 1, "b": 2)}, Path.all()) -> [["a", 1], ["b", 2]]`

Pseudocode example: `select([1, 2, 3], Path.all()) -> [1, 2, 3]`

For [proxies](/content/docs/~/pstates.html#_reactive_queries/index.html) transforms with this navigator produce diffs according to the type of data
    structure involved. For sequences produces [`SequenceIndexChangesDiff`](/content/javadoc/com/rpl/rama/diffs/SequenceIndexChangesDiff.html "class in com.rpl.rama.diffs"/index.html), [`SequenceIndexRemoveDiff`](/content/javadoc/com/rpl/rama/diffs/SequenceIndexRemoveDiff.html "class in com.rpl.rama.diffs"/index.html), or a combination. For sets produces [`SetAddDiff`](/content/javadoc/com/rpl/rama/diffs/SetAddDiff.html "class in com.rpl.rama.diffs"/index.html), [`SetRemoveDiff`](/content/javadoc/com/rpl/rama/diffs/SetRemoveDiff.html "class in com.rpl.rama.diffs"/index.html), or a combination. For maps produces [`KeyDiff`](/content/javadoc/com/rpl/rama/diffs/KeyDiff.html "class in com.rpl.rama.diffs"/index.html), [`KeyRemoveDiff`](/content/javadoc/com/rpl/rama/diffs/KeyRemoveDiff.html "class in com.rpl.rama.diffs"/index.html), or a combination. When multiple diffs are produces they are combined with [`MultiDiff`](/content/javadoc/com/rpl/rama/diffs/MultiDiff.html "class in com.rpl.rama.diffs"/index.html).

- ### mapKeys )

static[Path.Impl](/content/javadoc/com/rpl/rama/Path.Impl.html "interface in com.rpl.rama"/index.html)mapKeys()

Navigates to every key of a map. In transforms, changing a key is the same as removing
    the original key and then adding the updated key with the original value. Value navigator.

Pseudocode example: `select({"a": 1, "b": 2)}, Path.mapKeys()) -> ["a", "b"]`

For [proxies](/content/docs/~/pstates.html#_reactive_queries/index.html) transforms with this navigator produce
    [`KeysRemoveDiff`](/content/javadoc/com/rpl/rama/diffs/KeysRemoveDiff.html "class in com.rpl.rama.diffs"/index.html), [`KeysDiff`](/content/javadoc/com/rpl/rama/diffs/KeysDiff.html "class in com.rpl.rama.diffs"/index.html),
    or a combination of the two with [`MultiDiff`](/content/javadoc/com/rpl/rama/diffs/MultiDiff.html "class in com.rpl.rama.diffs"/index.html).

Navigates to a map containing subset of keys/values of starting map.
    Substructure navigator.

Pseudocode example: `select({"a": 1, "b": 2, "c": 3)}, Path.subMap("a", "c", "d")) -> [{"a": 1, "c": 3}]`

For [proxies](/content/docs/~/pstates.html#_reactive_queries/index.html) transforms with this navigator that do fine-grained updates to the submap produce
    [`KeysRemoveDiff`](/content/javadoc/com/rpl/rama/diffs/KeysRemoveDiff.html "class in com.rpl.rama.diffs"/index.html), [`KeysDiff`](/content/javadoc/com/rpl/rama/diffs/KeysDiff.html "class in com.rpl.rama.diffs"/index.html),
    or a combination of the two with [`MultiDiff`](/content/javadoc/com/rpl/rama/diffs/MultiDiff.html "class in com.rpl.rama.diffs"/index.html). If the submap is modified in a coarse-grained
    way (e.g. overridden completely with [`termVal(java.lang.Object)`](/content/javadoc/com/rpl/rama/Path.html#termVal(java.lang.Object))), this navigator will produce a [`NewValueDiff`](/content/javadoc/com/rpl/rama/diffs/NewValueDiff.html "class in com.rpl.rama.diffs"/index.html).

Parameters:`argKeys` \- Keys to select in starting map. Non-existing keys are ignored.
