Interface PlatformFontResolver

All Superinterfaces:

Serializable

All Known Implementing Classes:

PlatformFontResolverImpl

public interface PlatformFontResolver
extends Serializable

This interface provides access to the methods that a client can use to build a font set that is used to resolve platform font names into actual Font objects.

Concurrency

All classes that implement this interface are in general not guaranteed to be threadsafe. Specific implementations may offer tighter guarantees.

Method Summary

Modifier and Type	Method and Description
void	addFont(Font font) Adds a font to the set of fonts that are examined for resolving of platform names.
void	addFont(PlatformFontDescription platformDesc, Font font) Adds a font to the set of fonts that are examined for resolving of platform names.
Font	findFont(PlatformFontSearchAttributes searchAttributes) Find a Font that matches the provided description.
boolean	isEmpty()
FontResolutionPriority	setResolutionPriority(FontResolutionPriority priority) Set the resolution mechanism that the PlatformNameResoulver should use to decide which font should be chosen when two fonts have the same platform name.

Method Detail

setResolutionPriority

FontResolutionPriority setResolutionPriority(FontResolutionPriority priority)

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.

Parameters:

priority - The resolution mechanism to use

Returns:

The old resolution priority setting.

addFont

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

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.

Parameters:

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

Throws:

UnsupportedFontException

FontLoadingException

InvalidFontException

addFont

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

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.

Parameters:

platformDesc - the platform description of the font

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

Throws:

UnsupportedFontException

FontLoadingException

InvalidFontException

isEmpty

boolean isEmpty()

Returns:

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

findFont

Font findFont(PlatformFontSearchAttributes searchAttributes)

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

Parameters:

searchAttributes - the platform font attributes to search for

Returns:

the Font.
