Method Details

getName

public String getName()

Specified by:

getName in interface NamedNode<FragmentDefinition>

Returns:

the name of this node

getTypeCondition

public TypeName getTypeCondition()

getDirectives

public List<Directive> getDirectives()

Description copied from interface: DirectivesContainer

This will return a list of all the directives that have been put on Node as a flat list, which may contain repeatable and non repeatable directives.

Specified by:

getDirectives in interface DirectivesContainer<FragmentDefinition>

Returns:

a list of all the directives associated with this Node

getDirectivesByName

public Map<String,List<Directive>> getDirectivesByName()

Description copied from interface: DirectivesContainer

This will return a Map of the all directives that are associated with a Node, including both repeatable and non repeatable directives.

Specified by:

getDirectivesByName in interface DirectivesContainer<FragmentDefinition>

Returns:

a map of all directives by directive name

getDirectives

public List<Directive> getDirectives(String directiveName)

Description copied from interface: DirectivesContainer

Returns all the directives with the provided name, including repeatable and non repeatable directives.

Specified by:

getDirectives in interface DirectivesContainer<FragmentDefinition>

Parameters:

directiveName - the name of the directives to retrieve

Returns:

the directives or empty list if there is not one with that name

hasDirective

public boolean hasDirective(String directiveName)

Description copied from interface: DirectivesContainer

This returns true if the AST node contains one or more directives by the specified name

Specified by:

hasDirective in interface DirectivesContainer<FragmentDefinition>

Parameters:

directiveName - the name ot check

Returns:

true if the AST node contains one or more directives by the specified name

getSelectionSet

public SelectionSet getSelectionSet()

Specified by:

getSelectionSet in interface SelectionSetContainer<FragmentDefinition>

getChildren

public List<Node> getChildren()

Specified by:

getChildren in interface Node<FragmentDefinition>

Returns:

a list of the children of this node

getNamedChildren

public NodeChildrenContainer getNamedChildren()

Description copied from interface: Node

Alternative to Node.getChildren() where the children are not all in one list regardless of type but grouped by name/type of the child.

Specified by:

getNamedChildren in interface Node<FragmentDefinition>

Returns:

a container of the child nodes

withNewChildren

public FragmentDefinition withNewChildren(NodeChildrenContainer newChildren)

Description copied from interface: Node

Replaces the specified children and returns a new Node.

Specified by:

withNewChildren in interface Node<FragmentDefinition>

Parameters:

newChildren - must be empty for Nodes without children

Returns:

a new node

isEqualTo

public boolean isEqualTo(Node o)

Description copied from interface: Node

Compares just the content and not the children.

Specified by:

isEqualTo in interface Node<FragmentDefinition>

Parameters:

o - the other node to compare to

Returns:

isEqualTo

deepCopy

public FragmentDefinition deepCopy()

Specified by:

deepCopy in interface Node<FragmentDefinition>

Returns:

a deep copy of this node

toString

public String toString()

Overrides:

toString in class Object

accept

public TraversalControl accept(TraverserContext<Node> context,
 NodeVisitor nodeVisitor)

Description copied from interface: Node

Double-dispatch entry point. A node receives a Visitor instance and then calls a method on a Visitor that corresponds to a actual type of this Node. This binding however happens at the compile time and therefore it allows to save on rather expensive reflection based instanceOf check when decision based on the actual type of Node is needed, which happens redundantly during traversing AST. Additional advantage of this pattern is to decouple tree traversal mechanism from the code that needs to be executed when traversal "visits" a particular Node in the tree. This leads to a better code re-usability and maintainability.

Specified by:

accept in interface Node<FragmentDefinition>

Parameters:

context - TraverserContext bound to this Node object

nodeVisitor - Visitor instance that performs actual processing on the Nodes(s)

Returns:

Result of Visitor's operation. Note! Visitor's operation might return special results to control traversal process.

newFragmentDefinition

public static FragmentDefinition.Builder newFragmentDefinition()

transform

public FragmentDefinition transform(Consumer<FragmentDefinition.Builder> builderConsumer)
