public final class AndNode implements Node

Node that represents logical AND of nodes.

Summary

Public constructors
AndNode(@NonNull List<Node> childNodes)

Constructor for AndNode that represents logical AND over all its child nodes.
AndNode(
    @NonNull Node firstChild,
    @NonNull Node secondChild,
    @NonNull Node[] additionalChildren
)

Convenience constructor for AndNode that represents logical AND over all its child nodes and takes in a varargs of nodes.

Public methods
void
addChild(@NonNull Node childNode)

Add a child node to the end of the current list of child nodes mChildren.
boolean
@NonNull List<Node>

Get the list of nodes being logically ANDed over by this node.
int

Returns the index of the first instance of the node, or -1 if the node does not exist.
int
boolean

Removes the given Node from the list of child nodes.
void
setChild(int index, @NonNull Node childNode)

Replace the child node at the provided index with the provided Node.
void
setChildren(@NonNull List<Node> childNodes)

Set the nodes being logically ANDed over by this node.
@NonNull String

Gets the string representation of AndNode.

Public constructors

AndNode

Added in 1.1.0-alpha07
public AndNode(@NonNull List<Node> childNodes)

Constructor for AndNode that represents logical AND over all its child nodes.

Parameters
@NonNull List<Node> childNodes

The list of Node of at least size two representing queries to be logically ANDed over.

AndNode

public AndNode(
    @NonNull Node firstChild,
    @NonNull Node secondChild,
    @NonNull Node[] additionalChildren
)

Convenience constructor for AndNode that represents logical AND over all its child nodes and takes in a varargs of nodes.

Parameters
@NonNull Node firstChild

The first node to be ANDed over, which is required.
@NonNull Node secondChild

The second node to be ANDed over, which is required.
@NonNull Node[] additionalChildren

Additional nodes to be ANDed over, which are optional.

Public methods

addChild

Added in 1.1.0-alpha07
public void addChild(@NonNull Node childNode)

Add a child node to the end of the current list of child nodes mChildren.

Parameters
@NonNull Node childNode

A Node to add to the end of the list of child nodes.

equals

public boolean equals(Object o)

getChildren

public @NonNull List<Node> getChildren()

Get the list of nodes being logically ANDed over by this node.

getIndexOfChild

Added in 1.1.0-alpha07
public int getIndexOfChild(@NonNull Node node)

Returns the index of the first instance of the node, or -1 if the node does not exist.

hashCode

public int hashCode()

removeChild

Added in 1.1.0-alpha07
public boolean removeChild(@NonNull Node node)

Removes the given Node from the list of child nodes. If multiple copies of the node exist, then the first Node that matches the provided Node will be removed. If the node does not exist, the list will be unchanged.

The list of child nodes must contain at least 3 nodes to perform this operation.

Returns
boolean

true if the node was removed, false if the node was not removed i.e. the node was not found.

setChild

Added in 1.1.0-alpha07
public void setChild(int index, @NonNull Node childNode)

Replace the child node at the provided index with the provided Node.

Parameters
int index

The index at which to replace the child node in the list of child nodes. Must be in range of the size of mChildren.
@NonNull Node childNode

The Node that is replacing the childNode at the provided index.

setChildren

Added in 1.1.0-alpha07
public void setChildren(@NonNull List<Node> childNodes)

Set the nodes being logically ANDed over by this node.

Parameters
@NonNull List<Node> childNodes

A list of Node of at least size two representing the nodes to be logically ANDed over in this node.

toString

public @NonNull String toString()

Gets the string representation of AndNode.

The string representation of AndNode is the string representation of AndNode's child nodes joined with "AND", all surrounded by parentheses.
