Class java.awt.font.GlyphJustificationInfo 

java.lang.Object
    |
    +----java.awt.font.GlyphJustificationInfo
public final class GlyphJustificationInfo
extends Object
GlyphJustificationInfo represents information about the justification properties of a glyph.

Weight is the overall 'weight' of the glyph in the line. Generally it is proportional to the size of the font. Glyphs with larger weight are allocated a correspondingly larger amount of the change in space.

Priority determines the justification phase in which this glyph is used. All glyphs of the same priority are examined before glyphs of the next lower priority. If all the change in space can be allocated to these glyphs without exceeding their limits, then lower priority glyphs are not examined.

Absorb determines whether a glyph absorbs all change in space. Within a given priority, some glyphs may absorb all the change in space. If any of these glyphs are present, no glyphs of lower priority will be examined.

Limit determines the maximum or minimum amount by which the glyph can change. Left and right sides of the glyph may have different limits.

Each justification info represents two sets of metrics, growing and shrinking. Growing metrics are used when the glyphs on a line are to be spread apart to fit a larger width, shrinking metrics are used when the glyphs are to be moved together to fit a smaller width.

Example: Querying a Font for justification information 

 Font font = ...;
 int glyphCode = ...;
 GlyphJustificationInfo info = font.getGlyphJustificationInfo(glyphCode);
