public enum NodeNameMatchers
extends java.lang.Enum<NodeNameMatchers>
implements NodeMatcher<java.lang.String>

An enumeration class with several pre-defined NodeMatcher implementations based on node names.

Filtering nodes by their name is a typical use case. Therefore, some default implementations for typical filter algorithms are already provided. They are available as constants of this class. Because the algorithms are state-less these instances can be shared and accessed concurrently.

Since:

2.0

Enum Constant Detail

EQUALS

public static final NodeNameMatchers EQUALS

A matcher for exact node name matches. This matcher returns true if and only if the name of the passed in node equals exactly the given criterion string.

EQUALS_IGNORE_CASE

public static final NodeNameMatchers EQUALS_IGNORE_CASE

A matcher for matches on node names which ignores case. For this matcher the names node, NODE, or NodE are all the same.

Method Detail

values

public static NodeNameMatchers[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NodeNameMatchers c : NodeNameMatchers.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NodeNameMatchers valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
