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
