Module: IPXACT

Defined in:
lib/ipxact.rb

Overview

Root and commodity module for the IPXACT Ruby library. In particular, this module should be used for loading the component design files.

Examples:

Default initialization process

component_docs = IPXACT::load_components("my/component/path")
design_docs = IPXACT::load_designs("my/design/path")
platform = IPXACT::Parser::PlatformData::parse_platform("platform_id",
                                          component_docs, design_docs)

Class Method Details

.identifier(path) ⇒ Hash

Returns the component’s identifier (i.e., name, library, vendor, version) from a design or component file.

Parameters:

  • path (String) —

    The path to the component’s XML file

Returns:

  • (Hash) —

    The component’s identifier or nil if the path is invalid

def self.identifier(path)

    ipxact_file = File.open(path)
    ipxact_doc = Nokogiri::XML(ipxact_file)
    ipxact_file.close

    IPXACT::Parser::IdentifierData.parse_identifier(ipxact_doc.xpath('./*'))
  else
    nil
  end
end

.is_valid_component?(path) ⇒ Boolean

Returns whether the XML file is an IPXACT component (i.e., it is consistent with the component.xsd schema.

Parameters:

  • file_path (String) —

    path to the file that should be tested

Returns:

  • (Boolean) —

    whether the file is a valid IPXACT component

Raises:

  • (ArgumentError)

end

.is_valid_design?(path) ⇒ Boolean

Returns whether the XML file is an IPXACT design (i.e., it is consistent with the design.xsd schema).

Parameters:

  • file_path (String) —

    path to the file that should be tested

Returns:

  • (Boolean) —

    whether the file is a valid IPXACT design

Raises:

  • (ArgumentError)

  design_file.close

end

.load_components(components_path) ⇒ Hash

Loads the components from an IPXACT XML specification.

Parameters:

  • components_path (String) —

    path to the components of the target platform. All subdirectories will be scanned and all valid files (i.e., from an XML and component.xsd schema point of view) are loaded into the resulting structure.

Returns:

  • (Hash) —

    a Hash that associates the name and version of the component with the IPXACT XML (Nokogiri) structure of the component. No post-processing is made on this structure, which should not be used for any serious work (i.e.,its values may be modified when instantiating any design file linked to the components).

Raises:

  • a generic exception if no component could be found.

.load_designs(designs_path) ⇒ Hash

Loads the designs from an IPXACT XML specification.

with the IPXACT XML (Nokogiri) structure of the design. Should not be used, as this is ‘raw’ IPXACT data.

Parameters:

  • designs_path (String) —

    a path to the design instances of the target platform. All subdirectories will be scanned and all valid files (i.e., from an XML and design.xsd schema point of view) are loaded into the resulting structure.

Returns:

  • (Hash) —

    a Hash that associates the name and version of the design

Raises:

  • a generic exception if no design document could be found.
