java.lang.Object | +----java.awt.font.GlyphJustificationInfo
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);

weight
- the weight of this glyph
growAbsorb
- if true, when growing this glyph absorbs all extra
space at this and lower priority levels
growPriority
- the priority level of this glyph when growing
growLeftLimit
- the maximum amount by which the left side of this
glyph can grow
growRightLimit
- the maximum amount by which the right side of this
glyph can grow
shrinkAbsorb
- if true, when shrinking this glyph absorbs all
remaining shrinkage at this and lower priority levels
shrinkPriority
- the priority level of this glyph when shrinking
shrinkLeftLimit
- the maximum amount by which the left side of this
glyph can shrink (a positive number)
shrinkRightLimit
- the maximum amoun by which the right side of
this glyph can shrink (a postive number)
