Method Detail

addFont

public void addFont(Font font)
             throws UnsupportedFontException,
                    InvalidFontException,
                    FontLoadingException

Description copied from interface: PlatformFontResolver

Adds a font to the set of fonts that are examined for resolving of platform names. If this font is indistinguishable from another font already in the font set then which of the two that is kept is determined by the settings of FontResolutionPriority.

Specified by:

addFont in interface PlatformFontResolver

Parameters:

font - the font to add to the fonts used for platform resolution

Throws:

UnsupportedFontException

InvalidFontException

FontLoadingException

addFont

public void addFont(PlatformFontDescription fontDesc,
                    Font font)
             throws UnsupportedFontException,
                    InvalidFontException,
                    FontLoadingException

Description copied from interface: PlatformFontResolver

Adds a font to the set of fonts that are examined for resolving of platform names. If this font's PlatformFontDescription is indistinguishable from another font already in the font set then which of the two that is kept is determined by the settings of FontResolutionPriority.

Note that the PlatformFontDescription is NOT pushed down into the Font. It is only an alias in the database. Thus, calling font.getPostscriptFontDescription() will not return the description passed in through this method but will instead return the original platform description of the font.

Specified by:

addFont in interface PlatformFontResolver

Parameters:

fontDesc - the platform description of the font

font - the font to add to the fonts used for platform resolution

Throws:

UnsupportedFontException

InvalidFontException

FontLoadingException

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface PlatformFontResolver

Returns:

true if the font set is empty (has no fonts); false otherwise

setResolutionPriority

public FontResolutionPriority setResolutionPriority(FontResolutionPriority priority)

Description copied from interface: PlatformFontResolver

Set the resolution mechanism that the PlatformNameResoulver should use to decide which font should be chosen when two fonts have the same platform name.

FontResolutionPriority.INTELLIGENT_FIRST specifies that an "intelligent" determination is made about the fonts and the "better" of the two font is chosen. If the "intelligent" resolver can make no distinction between the fonts then the first font to have been added first is chosen.

FontResolutionPriority.INTELLIGENT_LAST specifies that an "intelligent" determination is made about the fonts and the "better" of the two font is chosen. If the "intelligent" resolver can make no distinction between the fonts then the first font to have been added last is chosen.

FontResolutionPriority.FIRST specifies the first font added to the font set that matches the platform attributes is chosen.

FontResolutionPriority.LAST specifies the last font added to the font set that matches the platform attributes is chosen.

Specified by:

setResolutionPriority in interface PlatformFontResolver

Parameters:

priority - The resolution mechanism to use

Returns:

The old resolution priority setting.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

findFont

public Font findFont(PlatformFontSearchAttributes searchAttributes)

Description copied from interface: PlatformFontResolver

Find a Font that matches the provided description. No analysis (e.g., removal of a CMap extension) is done by this function.

Specified by:

findFont in interface PlatformFontResolver

Parameters:

searchAttributes - the platform font attributes to search for

Returns:

the Font.
