Member Function Documentation

applyContextualSubstitution()

virtual void JawsMako::IUnicodeHelper::applyContextualSubstitution ( String & input ) const

pure virtual

Applies the language's contextual substitution rules, in place.

Parameters

input

The string to apply the contextual substitution to.

applyDiacriticFixes()

virtual void JawsMako::IUnicodeHelper::applyDiacriticFixes ( CTextRunVect & runs ) const

pure virtual

Checks and attempts to fix diacritic characters that are incorrectly ordered.

Parameters

runs	The collection of text runs to apply the fixes to.

constructStringFromRuns()

virtual String JawsMako::IUnicodeHelper::constructStringFromRuns ( CTextRunVect & runs ) const

pure virtual

Creates a string from a CTextRunVect by applying diacritic fixes and contextual substitution, if required. The supplied runs collection must be contain unicode strings of length one. Basically the glyphs need to be in their single character form.

Parameters

runs	The collection of text runs to construct the string from.

Returns

String The constructed string.

create()

static JAWSMAKO_API IUnicodeHelperPtr JawsMako::IUnicodeHelper::create ( eLanguageType language )

static

Creates a unicode helper for the specified language.

Parameters

language

The language type for which the helper should be created.

Returns

IUnicodeHelperPtr A smart pointer to the unicode helper for the specified language.

getNonContextualCharacter()

virtual wchar_t JawsMako::IUnicodeHelper::getNonContextualCharacter ( const wchar_t ch ) const

pure virtual

Performs a reverse mapping on a contextual character and returns the original.

Parameters

ch	The contextual character to reverse.

Returns

wchar_t The original character.

hasContextualForms()

virtual bool JawsMako::IUnicodeHelper::hasContextualForms ( ) const

pure virtual

Returns true if the language has contextual forms.

Returns

bool True if the language has contextual forms, false otherwise.

isCombiningCharacter()

virtual bool JawsMako::IUnicodeHelper::isCombiningCharacter ( const wchar_t wchar ) const

pure virtual

Returns true is wchar is within the language's combining character ranges.

Parameters

wchar

The character to check.

Returns

bool True if the character is a combining character, false otherwise.

isSpaceCharacter()

static JAWSMAKO_API bool JawsMako::IUnicodeHelper::isSpaceCharacter ( wchar_t ch )

static

Returns true if ch is a unicode space character.

Parameters

ch	The character to check.

Returns

bool True if the character is a space character, false otherwise.
