Constructor Detail

### ComponentConfig

    public ComponentConfig(String name,
                           String description,
                           String classname,
                           String... classpath)

  Create a component configuration.

  Parameters:
    `name` - the name of the configuration, which is considered to be a unique identifier
    `description` - the description
    `classname` - the name of the Java class used for the component
    `classpath` - the optional classpath (defined in a way compatible with a `ClassLoaderFactory`
  Throws:
    `IllegalArgumentException` - if the name is null, empty or blank, or if the classname is null, empty or not a valid Java classname

### ComponentConfig

    public ComponentConfig(String name,
                           String description,
                           Map<String,Object> properties,
                           String classname,
                           String... classpath)

  Create a component configuration.

  Parameters:
    `name` - the name of the configuration, which is considered to be a unique identifier
    `description` - the description
    `properties` - the mapping of properties to values that should be set through reflection after a component is instantiated with this configuration information
    `classname` - the name of the Java class used for the component
    `classpath` - the optional classpath (defined in a way compatible with a `ClassLoaderFactory`
  Throws:
    `IllegalArgumentException` - if the name is null, empty or blank, or if the class name is null, empty or not a valid Java class name

### ComponentConfig

    public ComponentConfig(String name,
                           String description,
                           long timestamp,
                           Map<String,Object> properties,
                           String classname,
                           String... classpath)

  Create a component configuration.

  Parameters:
    `name` - the name of the configuration, which is considered to be a unique identifier
    `description` - the description
    `timestamp` - the timestamp that this component was last changed
    `properties` - the mapping of properties to values that should be set through reflection after a component is instantiated with this configuration information
    `classname` - the name of the Java class used for the component
    `classpath` - the optional classpath (defined in a way compatible with a `ClassLoaderFactory`
  Throws:
    `IllegalArgumentException` - if the name is null, empty or blank, or if the classname is null, empty or not a valid Java classname

Method Detail

### getName

    public String getName()

  Get the name of this component.

  Returns:
    the component name; never null, empty or blank

### getDescription

    public String getDescription()

  Get the description for this component

  Returns:
    the description

### getComponentClassname

    public String getComponentClassname()

  Get the fully-qualified name of the Java class used for instances of this component

  Returns:
    the Java class name of this component; never null or empty and always a valid Java class name

### getComponentClasspath

    public List<String> getComponentClasspath()

  Get the classpath defined in terms of strings compatible with a `ClassLoaderFactory`.

  Returns:
    the classpath; never null but possibly empty

### getComponentClasspathArray

    public String[] getComponentClasspathArray()

  Get the classpath defined as an array of strings compatible with a `ClassLoaderFactory`.

  Returns:
    the classpath as an array; never null but possibly empty

### getTimestamp

    public long getTimestamp()

  Get the system timestamp when this configuration object was created.

  Returns:
    the timestamp

### getProperties

    public Map<String,Object> getProperties()

  Get the (unmodifiable) properties to be set through reflection on components of this type after instantiation

  Returns:
    the properties to be set through reflection on components of this type after instantiation; never null

### compareTo

    public int compareTo(ComponentConfig that)

  Specified by:
    `compareTo` in interface `Comparable<ComponentConfig>`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`

### equals

    public boolean equals(Object obj)

  Overrides:
    `equals` in class `Object`

### hasChanged

    public boolean hasChanged(ComponentConfig component)

  Determine whether this component has changed with respect to the supplied component. This method basically checks all attributes, whereas `equals` only checks the `type` and `getName()`.

  Parameters:
    `component` - the component to be compared with this one
  Returns:
    true if this componet and the supplied component have some changes, or false if they are exactly equivalent
  Throws:
    `IllegalArgumentException` - if the supplied component reference is null or is not the same `type` as this object
