decode()

The function decode accepts a document, a content type and an optional continuation, It parses the document and returns or continues with the result, by retrieving the respective decoder and delegating the operation to that function.

fieldDefinition(identifier) → {PropertyDefinition}

Given a property identifier, return the definition from the environment's context.

Parameters:
Name Type Description
identifier string | URL

An identifier present in the context
Inherited From:
To Do:
  • The definition should be a standard JavaScript property descriptor
  • Change name to getPropertyDescriptor

PropertyDefinition

fieldType()

Given a property identifier, return the type from its definition

Inherited From:
To Do:
  • Change name to getPropertyType

View Source graph-environment.js, line 132

findIdentifierName()

Given an IRI, return the property name associated with it in the environment. If none is present in the context, add a definition which specifies the IRI leaf as the name. The first probe searches the context for a property definition which specifies the iri as its @id. That result is then cached for future references.

Inherited From:

View Source graph-environment.js, line 144

findNameIdentifier(name)

Given a property name, return the IRI associated with it in the environment.

Parameters:
Name Type Description
name string
Inherited From:

View Source graph-environment.js, line 181

graphResourceID(graph)

Return the identifier for the root node of the given Graph.

Parameters:
Name Type Description
graph Graph
Overrides:

View Source graph-environment.js, line 84

graphResourceIDs(graph)

Return the identifers for all nodes in the given Graph.

Parameters:
Name Type Description
graph Graph
Overrides:

resolveContext(context)

Accept a context designator, retrieve if necessary, expand all definitions, and bind the environment's context property to it.

Parameters:
Name Type Description
context string | URL | Context

The context to resolve.

toLiteral()

The function toLiteral accepts an native object and coerces it to a Literal instance. It distinguishes between Object specializations and primitive data. In those cases, use the type to compute a converter and delegate to that. Return unmodified any data which is already a Term.

toValue()

The function toValue accepts a Term and converts it to a native value
