Class ImmutableNode.Builder

java.lang.Object
org.apache.commons.configuration2.tree.ImmutableNode.Builder
Enclosing class:
ImmutableNode
public static final class ImmutableNode.Builder extends Object

A builder class for creating instances of ImmutableNode.

This class can be used to set all properties of an immutable node instance. Eventually call the create() method to obtain the resulting instance.

Implementation note: This class is not thread-safe. It is intended to be used to define a single node instance only.

  • Constructor Details

    • Builder

      public Builder()
      Creates a new instance of Builder which does not contain any property definitions yet.

    • Builder

      public Builder(int childCount)
      Creates a new instance of Builder and sets the number of expected child nodes. Using this constructor helps the class to create a properly sized list for the child nodes to be added.
      Parameters:
      childCount - the number of child nodes

  • Method Details

    • addAttribute

      public ImmutableNode.Builder addAttribute(String name, Object value)
      Adds an attribute to this builder. The passed in attribute key and value are stored in an internal map. If there is already an attribute with this name, it is overridden.
      Parameters:
      name - the attribute name
      value - the attribute value
      Returns:
      a reference to this object for method chaining

    • addAttributes

      public ImmutableNode.Builder addAttributes(Map<String,?> attrs)
      Adds all attributes of the given map to this builder. This method works like addAttribute(String, Object), but it allows setting multiple attributes at once.
      Parameters:
      attrs - the map with attributes to be added (may be null
      Returns:
      a reference to this object for method chaining

    • addChild

      public ImmutableNode.Builder addChild(ImmutableNode c)
      Adds a child node to this builder. The passed in node becomes a child of the newly created node. If it is null, it is ignored.
      Parameters:
      c - the child node (must not be null)
      Returns:
      a reference to this object for method chaining

    • addChildren

      public ImmutableNode.Builder addChildren(Collection<? extends ImmutableNode> children)
      Adds multiple child nodes to this builder. This method works like addChild(ImmutableNode), but it allows setting a number of child nodes at once.
      Parameters:
      children - a collection with the child nodes to be added
      Returns:
      a reference to this object for method chaining

    • create

      public ImmutableNode create()
      Creates a new ImmutableNode instance based on the properties set for this builder.
      Returns:
      the newly created ImmutableNode

    • name

      public ImmutableNode.Builder name(String n)
      Sets the name of the node to be created.
      Parameters:
      n - the node name
      Returns:
      a reference to this object for method chaining

    • value

      public ImmutableNode.Builder value(Object v)
      Sets the value of the node to be created.
      Parameters:
      v - the value
      Returns:
      a reference to this object for method chaining
