simplenlg.phrasespec.NPPhraseSpec

This class defines a noun phrase. It is essentially a wrapper around the PhraseElement class, with methods for setting common constituents such as specifier. For example, the setNoun method in this class sets the head of the element to be the specified noun From an API perspective, this class is a simplified version of the NPPhraseSpec class in simplenlg V3. It provides an alternative way for creating syntactic structures, compared to directly manipulating a V4 PhraseElement. Methods are provided for setting and getting the following constituents:

Specifier (eg, "the")
PreModifier (eg, "green")
Noun (eg, "apple")
PostModifier (eg, "in the shop")

NOTE: The setModifier method will attempt to automatically determine whether a modifier should be expressed as a PreModifier, or PostModifier NOTE: Specifiers are currently pretty basic, this needs more development Features (such as number) must be accessed via the setFeature and getFeature methods (inherited from NLGElement). Features which are often set on NPPhraseSpec include

Number (eg, "the apple" vs "the apples")
Possessive (eg, "John" vs "John's")
Pronominal (eg, "the apple" vs "it")

NPPhraseSpec are produced by the createNounPhrase method of a PhraseFactory
