Class ModuleRules<T>

java.lang.Object
org.apache.ivy.core.module.id.ModuleRules<T>
Type Parameters:
T - a type parameter
public class ModuleRules<T> extends Object
A list of module specific rules.

This class defines a list of module specific rules. For each module only one rule apply, sometimes none.

To know which rule to apply, they are configured using matchers. So you can define a rule applying to all module from one particular organization, or to all modules with a revisions matching a pattern, and so on.

Rules condition are evaluated in order, so the first matching rule is returned.

Rules themselves can be represented by any object, depending on the purpose of the rule (define which resolver to use, which TTL in cache, ...)

    • ModuleRules

      public ModuleRules()
      Constructs an empty ModuleRules.

  • Method Details

    • defineRule

      public void defineRule(MapMatcher condition, T rule)
      Defines a new rule for the given condition.
      Parameters:
      condition - the condition for which the rule should be applied. Must not be null.
      rule - the rule to apply. Must not be null.

    • getRule

      public T getRule(ModuleId mid)
      Returns the rule object matching the given ModuleId, or null if no rule applies.
      Parameters:
      mid - the ModuleId to search the rule for. Must not be null.
      Returns:
      the rule object matching the given ModuleId, or null if no rule applies.

    • getRules

      public List<T> getRules(ModuleId mid)
      Returns the rules objects matching the given ModuleId, or an empty array if no rule applies.
      Parameters:
      mid - the ModuleId to search the rule for. Must not be null.
      Returns:
      an array of rule objects matching the given ModuleId.

    • getRule

      public T getRule(ModuleRevisionId mrid)
      Returns the rule object matching the given ModuleRevisionId, or null if no rule applies.
      Parameters:
      mrid - the ModuleRevisionId to search the rule for. Must not be null .
      Returns:
      the rule object matching the given ModuleRevisionId, or null if no rule applies.

    • getRule

      public T getRule(ModuleId mid, Filter<T> filter)
      Returns the rule object matching the given ModuleId and accepted by the given Filter, or null if no rule applies.
      Parameters:
      mid - the ModuleRevisionId to search the rule for. Must not be null .
