Detailed Description

This class defines a lexicon useful to analyse and recognize the different key words included in a sentence. The lexicon is stored in a sequence of tokens.

Constructor & Destructor Documentation

Units_Lexicon::Units_Lexicon ( )

Creates an empty instance of Lexicon.

Member Function Documentation

void Units_Lexicon::AddToken ( const Standard_CString  aword,
const Standard_CString  amean,
const Standard_Real  avalue 
)

Adds to the lexicon a new token with <aword>, <amean>, <avalue> as arguments. If there is already a token with the field <theword> equal to <aword>, the existing token is updated.

void Units_Lexicon::Creates ( const Standard_CString  afilename)

Reads the file <afilename> to create a sequence of tokens stored in <thesequenceoftokens>.

virtual void Units_Lexicon::Dump ( ) const
virtual

Useful for debugging.

Reimplemented in Units_UnitsLexicon.

TCollection_AsciiString Units_Lexicon::FileName ( ) const

Returns in a AsciiString from TCollection the name of the file.

Handle< Units_TokensSequence > Units_Lexicon::Sequence ( ) const

Returns the first item of the sequence of tokens.

virtual Standard_Boolean Units_Lexicon::UpToDate ( ) const
virtual

Returns true if the file has not changed since the creation of the Lexicon object. Returns false otherwise.

Reimplemented in Units_UnitsLexicon.
