Class UsageFinder

  • public class UsageFinder
extends Object
    Visitor to generate usage counts for schema components. This is somewhat messy, since there are so many different types of references in schema: 'ref' (attribute, attributeGroup, element, and group, to reference a global definition of same type), 'type' (attribute and element, reference a global type definition), 'base' (extension and restriction), 'itemType' (list), 'memberTypes' (union), 'substitutionGroup' (element), and 'refer' (unique). References can be recursively expanded by matching the reference set against the set of components processed, and processing any new references until the closure is obtained.

        Constructor.

    • Method Detail

      • getUsageMap

        public org.jibx.util.ReferenceCountMap getUsageMap()
        Get map of reference counts per component.
        Returns:
        count map

      • getNonSingletonSet

        public Set getNonSingletonSet()
        Get the set of definitions referenced as optional or repeating.
        Returns:
        set

      • countSchemaTree

        public void countSchemaTree​(SchemaElement schema)
        Add usage counts for a schema tree. This counts all references from the supplied schema, including references in other schemas referenced by the schema.
        Parameters:
        schema - Schema Element

      • addReferenceClosure

        public void addReferenceClosure​(AnnotatedBase comp)
        Add usage counts for the reference closure of a definition.
        Parameters:
        comp - definition to be processed

      • addReferenceClosure

        public void addReferenceClosure​(List list)
        Add usage counts for the reference closure of a supplied list of components.
        Parameters:
        list - starting schema components

      • setNameRegister

        public void setNameRegister​(NameRegister reg)
        Set the register to be used for resolving name references. This is not needed if counting references from a schema tree using countSchemaTree(SchemaElement), which always sets the register associated with the supplied schema.
        Parameters:
        reg - Name register

      • reset

        public void reset()
        Clear the accumulated usage counts.
