public AbstractBackendFontManager()

Creates a new object.

Method Detail

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()

reset

public void reset()

Rest the internal state to the initial state. Afterwards the instance does not know anything about recognized fonts and can be used like a newly created instance.

Specified by:

reset in interface BackendFontManager

See Also:

BackendFontManager.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
