Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public boolean canDisplay (int cp)

public boolean canDisplay (char c)

public boolean canDoStyle (int style)

public int charToGlyph (int wchar)

public byte getBaselineFor (char c)

public String getFamilyName (Locale l)

public void getFontMetrics (Font font, AffineTransform at, Object aaHint, Object fmHint, float[] metrics)

The length of the metrics array must be >= 8. This method will store the following elements in that array before returning: metrics[0]: ascent metrics[1]: descent metrics[2]: leading metrics[3]: max advance metrics[4]: strikethrough offset metrics[5]: strikethrough thickness metrics[6]: underline offset metrics[7]: underline thickness

public void getFontMetrics (Font font, FontRenderContext frc, float[] metrics)

The length of the metrics array must be >= 4. This method will store the following elements in that array before returning: metrics[0]: ascent metrics[1]: descent metrics[2]: leading metrics[3]: max advance

public String getFontName (Locale l)

public float getItalicAngle (Font font, AffineTransform at, Object aaHint, Object fmHint)

public int getMissingGlyphCode ()

public int getNumGlyphs ()

public String getPostscriptName ()

public FontStrike getStrike (Font font, AffineTransform devTx, AffineTransform glyphTx, int aa, int fm)

public FontStrike getStrike (Font font)

public FontStrike getStrike (Font font, AffineTransform devTx, int aa, int fm)

public FontStrike getStrike (Font font, FontRenderContext frc)

public int getStyle ()

public void getStyleMetrics (float pointSize, float[] metrics, int offset)

The length of the metrics array must be >= offset+4, and offset must be >= 0. Typically offset is 4. This method will store the following elements in that array before returning: metrics[off+0]: strikethrough offset metrics[off+1]: strikethrough thickness metrics[off+2]: underline offset metrics[off+3]: underline thickness Note that this implementation simply returns default values; subclasses can override this method to provide more accurate values.
