Constructor Detail

ArrayNode

public ArrayNode(java.util.List<Node> elements,
                 SourceLocation sourceLocation)

Method Detail

iterator

public java.util.Iterator<Node> iterator()

Specified by:

iterator in interface java.lang.Iterable<Node>

getType

public NodeType getType()

Description copied from class: Node

Gets the type of the node.

Specified by:

getType in class Node

Returns:

Returns the node type.

accept

public <R> R accept(NodeVisitor<R> visitor)

Description copied from class: Node

Accepts a visitor with the node.

Specified by:

accept in class Node

Type Parameters:

R - visitor return type.

Parameters:

visitor - Visitor to dispatch to.

Returns:

Returns the accepted result.

expectArrayNode

public ArrayNode expectArrayNode(java.lang.String errorMessage)

Description copied from class: Node

Casts the current node to an ArrayNode, throwing ExpectationNotMetException when the node is the wrong type.

Overrides:

expectArrayNode in class Node

Parameters:

errorMessage - Error message to use if the node is of the wrong type.

Returns:

Returns an array node.

asArrayNode

public java.util.Optional<ArrayNode> asArrayNode()

Description copied from class: Node

Gets the node as an ArrayNode if it is an array.

Overrides:

asArrayNode in class Node

Returns:

Returns the optional array node.

getElements

public java.util.List<Node> getElements()

Gets the list of nodes.

Returns:

Returns a list of nodes.

get

public java.util.Optional<Node> get(int index)

Gets a node from the given index.

Parameters:

index - Index of the value to get.

Returns:

Returns an optional node at the given index.

isEmpty

public boolean isEmpty()

Returns true if the array node is empty.

Returns:

Returns true if the array node is empty.

size

public int size()

Returns the number of elements in the array node.

Returns:

Returns the number of elements in the array node.

withValue

public ArrayNode withValue(Node node)

Copies the values from the current array node, adding the given node, returning them in a new ArrayNode.

Parameters:

node - The node to add.

Returns:

Returns a new array node.

getElementsAs

public <T extends Node> java.util.List<T> getElementsAs(java.lang.Class<T> type)

Gets the elements of the array as a list of a specific type of Node.

Type Parameters:

T - Type of Node to expect in each position.

Parameters:

type - Type of Node to expect in each position.

Returns:

Returns the List of the specified type.

Throws:

ExpectationNotMetException - if the list contains elements of a different type.

getElementsAs

public <T,K extends Node> java.util.List<T> getElementsAs(java.util.function.Function<K,T> f)

Gets the elements of the ArrayNode as a specific type by applying a mapping function to each node.

Each Node is cast to K and then mapped with the provided function to return type T.

 ArrayNode array = Node.fromStrings("foo", "baz", "bar");
 List<String> strings = array.getElementsAs(StringNode::getValue);
 

Type Parameters:

K - Expected Node type.

T - Mapping function return value.

Parameters:

f - Mapping function that takes K and return T.

Returns:

Returns the List of type T.
