Constructor Detail

BackendFontManagerList

public BackendFontManagerList()

Creates a new object.

Method Detail

add

public void add(BackendFontManager manager)

Add a new back-end font manager.

Parameters:

manager - the new manager.

get

public BackendFontManager get(int index)

Returns the BackendFontManager.

Parameters:

index - The index.

Returns:

Returns the BackendFontManager.

See Also:

List.get(int)

getRecognizedCharId

public BackendCharacter getRecognizedCharId()

Get the char info for the most recently recognized pair of font and character. If invoked before any character has been recognized successfully then null is returned.

Specified by:

getRecognizedCharId in interface BackendFontManager

Returns:

the char info for the most recently recognized font/character pair

See Also:

BackendFontManager.getRecognizedCharId()

getRecognizedFont

public BackendFont getRecognizedFont()

Get the font info for the most recently recognized pair of font and character. If invoked before any character has been recognized successfully then null is returned.

Specified by:

getRecognizedFont in interface BackendFontManager

Returns:

the font info for the most recently recognized font/character pair

See Also:

BackendFontManager.getRecognizedFont()

isNewRecongnizedFont

public boolean isNewRecongnizedFont()

Get the new font indicator for the most recently recognized pair of font and character. If the font has never been recognized before then true is returned. The font compared for this test is the back-end font – not the font passed in. This means that each time getRecognizedFont() returns a new font info this method returns true.

If invoked before any character has been recognized successfully then null is returned.

Specified by:

isNewRecongnizedFont in interface BackendFontManager

Returns:

the font info for the most recently recognized font/character pair

See Also:

BackendFontManager.isNewRecongnizedFont()

iterate

public java.util.Iterator<ManagerInfo> iterate()

Return the iterator for all recognized back-end fonts as ManagerInfo. The fonts are sorted by the name.

Specified by:

iterate in interface BackendFontManager

Returns:

the iterator for all recognized back-end font as ManagerInfo.

See Also:

BackendFontManager.iterate()

iterateManagerInfo

public java.util.Iterator<ManagerInfo> iterateManagerInfo()

TODO missing JavaDoc

Returns:

TODO

recognize

public boolean recognize(FontKey fontKey,
                         UnicodeChar uc)
                  throws FontException

Take a character and a font and see if they can be managed by this manager. The internal state is adjusted to report the font and the character appropriately after the invocation has returned.

Specified by:

recognize in interface BackendFontManager

Parameters:

fontKey - the font key for the character at hand

uc - the Unicode character at hand

Returns:

true iff the character is defined in the font given and a font of a requested format can be delivered.

Throws:

FontException - if a font error occurred.

BackendFontManager.recognize(org.extex.font.FontKey, org.extex.core.UnicodeChar)

reset

public void reset()

setBackendFontFactory

public void setBackendFontFactory(BackendFontFactory f)

Setter for the back-end font factory.

Specified by:

setBackendFontFactory in interface BackendFontManager

Parameters:

f - the back-end font factory to set
