  • Method Details

    • getOperatorFactory

      public OperatorFactory getOperatorFactory()
      Description copied from interface: FormulaContext
      Returns the operator registry. The Operator-registry contains all operator-implementations.
      Specified by:
      getOperatorFactory in interface FormulaContext
      Returns:
      the operator registry.

    • defineReference

      public void defineReference(Object name, Object value)

    • resolveReference

      public Object resolveReference(Object name)
      Description copied from interface: FormulaContext
      Resolves the given reference. How the name is interpreted by the outside system is an implementation detail.
      Specified by:
      resolveReference in interface FormulaContext
      Parameters:
      name - the name that identifies the reference.
      Returns:
      the resolved object.

    • getConfiguration

      public Configuration getConfiguration()
      Description copied from interface: FormulaContext
      Returns the local configuration of the formula.
      Specified by:
      getConfiguration in interface FormulaContext
      Returns:
      the local configuration.

    • getFunctionRegistry

      public FunctionRegistry getFunctionRegistry()
      Description copied from interface: FormulaContext
      Returns the function registry. The function registry grants access to all formula-function implementations.
      Specified by:
      getFunctionRegistry in interface FormulaContext
      Returns:
      the function registry.

    • resolveReferenceType

      public Type resolveReferenceType(Object name)
      Description copied from interface: FormulaContext
      Queries the type of the given reference. How the name is interpreted by the outside system is an implementation detail. This return a LibFormula type object matching the type of the object that would be returned by resolveReference.
      Specified by:
      resolveReferenceType in interface FormulaContext
      Parameters:
      name - the name that identifies the reference.
      Returns:
      the type of the resolved object.

    • getTypeRegistry

      public TypeRegistry getTypeRegistry()
      Description copied from interface: FormulaContext
      Returns the type registry. The type registry contains all type information and allows to convert values between different types.
      Specified by:
      getTypeRegistry in interface FormulaContext
      Returns:
      the function registry.

    • getLocalizationContext

      public LocalizationContext getLocalizationContext()
      Description copied from interface: FormulaContext
      Returns the localization context of this formula. The localization context can be used to query locale specific configuration settings.
      Specified by:
      getLocalizationContext in interface FormulaContext
      Returns:
      the localization context.

    • isReferenceDirty

      public boolean isReferenceDirty(Object name)
      Description copied from interface: FormulaContext
      Checks whether the external object referenced by name has changed.
      Specified by:
      isReferenceDirty in interface FormulaContext
      Parameters:
      name - the name that identifies the reference.
      Returns:
      true, if the reference has changed, false otherwise.
