java.lang.Object

org.jetbrains.mps.openapi.model.SNodeUtil

public class SNodeUtil
extends Object

This class implement complex operations on the node structure. Unlike the SNode implementations, which may focus on their specific needs, this class should consider all cases, e.g. replacing a node with a root node from another model

Modifier and Type	Method	Description
static Iterable<SNode>	getDescendants(Iterable<SNode> roots)	Iterate over subtrees of each node in a given sequence of 'root' nodes
static Iterable<SNode>	getDescendants(SModel model)	Iterates over all nodes in the given model.
static Iterable<SNode>	getDescendants(SNode node)	Iterates over the subtree starting at the given node.
static Iterable<SNode>	getDescendants(SNode node, Condition<SNode> condition, boolean includeFirst)	Iterates over the subtree starting at the given node.
static boolean	isAccessible(SNode node, SRepository inRepository)	Returns whether the given node belongs to the repository (or to one of its parent repositories).
static boolean	isInstanceOf(SNode node, SAbstractConcept concept)	For non-null node, SNode.isInstanceOfConcept(SAbstractConcept) is straightforward replacement
static SNode	replaceWithAnother(SNode node, SNode replacer)	Replaces a node with another, preserving attributes

Method Detail

isAccessible

public static boolean isAccessible(@NotNull
                                   SNode node,
                                   @NotNull
                                   SRepository inRepository)

Returns whether the given node belongs to the repository (or to one of its parent repositories).

isInstanceOf

public static boolean isInstanceOf(@Nullable
                                   SNode node,
                                   @NotNull
                                   SAbstractConcept concept)

For non-null node, SNode.isInstanceOfConcept(SAbstractConcept) is straightforward replacement

replaceWithAnother

public static SNode replaceWithAnother(@NotNull
                                       SNode node,
                                       SNode replacer)

Replaces a node with another, preserving attributes

getDescendants

public static Iterable<SNode> getDescendants(@NotNull
                                             SModel model)

Iterates over all nodes in the given model.

getDescendants

@NotNull
public static Iterable<SNode> getDescendants(@NotNull
                                             SNode node)

Iterates over the subtree starting at the given node.

getDescendants

@NotNull
public static Iterable<SNode> getDescendants(@NotNull
                                             SNode node,
                                             @Nullable
                                             Condition<SNode> condition,
                                             boolean includeFirst)

Iterates over the subtree starting at the given node.

Parameters:

condition - if not null, acts like a filter

includeFirst - false to skip the root node from the returned sequence

getDescendants

@NotNull
public static Iterable<SNode> getDescendants(@NotNull
                                             Iterable<SNode> roots)

Iterate over subtrees of each node in a given sequence of 'root' nodes
