class FeatureSet

Return Layer/Table set of features

• getCount(): Return set number of ocurrences

class Feature

Represents layer/table feature data

• geometry(): Return feature default geometry
• getValues(): Return dictionary with key name property and value of the feature attributes
• edit(): Return editable feature instance #FIXME

class Schema

Layer/table feature definition

• append(name, type[, size][, default]): Adds property to feature properties definition.
  • param name: Feature property name
  • type name: String
  • param type: Feature property type
  • type name: String
  • param size: Feature property size
  • type size: int
  • param default: Feature property default value
  • return: new atribute
• get(name, default=None): Looks for property name named and if not find it return default. Return a feature attribute descriptor that contains information about one of the attributes in a feature, such as its name, data type or precision.
  • param name: Property name
  • type name: string
  • param default: Return value if not find property name
  • type value: Object
  • return: AttributeDescriptor
• modify(): set definition in edition mode to add new properties
• getCopy(): Return schema copy
