Constructor Detail

AndDependencyFilter

public AndDependencyFilter(DependencyFilter... filters)

Creates a new filter from the specified filters. Prefer newInstance(DependencyFilter, DependencyFilter) if any of the input filters might be null.

Parameters:

filters - The filters to combine, may be null but must not contain null elements.

AndDependencyFilter

public AndDependencyFilter(Collection<DependencyFilter> filters)

Creates a new filter from the specified filters.

Parameters:

filters - The filters to combine, may be null but must not contain null elements.

Method Detail

newInstance

public static DependencyFilter newInstance(DependencyFilter filter1,
                                           DependencyFilter filter2)

Creates a new filter from the specified filters.

Parameters:

filter1 - The first filter to combine, may be null.

filter2 - The second filter to combine, may be null.

Returns:

The combined filter or null if both filter were null.

accept

public boolean accept(DependencyNode node,
                      List<DependencyNode> parents)

Description copied from interface: DependencyFilter

Indicates whether the specified dependency node shall be included or excluded.

Specified by:

accept in interface DependencyFilter

Parameters:

node - The dependency node to filter, must not be null.

parents - The (read-only) chain of parent nodes that leads to the node to be filtered, must not be null. Iterating this (possibly empty) list walks up the dependency graph towards the root node, i.e. the immediate parent node (if any) is the first node in the list. The size of the list also denotes the zero-based depth of the filtered node.

Returns:

true to include the dependency node, false to exclude it.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
