Constructor Detail

TextureRequest

public TextureRequest(RenderMeshFragment fragment,
                      double minX,
                      double minY,
                      double maxX,
                      double maxY,
                      float metersPerPixel)

Init a request

Parameters:

fragment -

minX -

minY -

maxX -

maxY -

metersPerPixel -

Method Detail

getFragment

public RenderMeshFragment getFragment()

Returns:

the fragment this request is generated for.

equals

public boolean equals(Object o)

Overrides:

equals in class TextureTileRequest

hashCode

public int hashCode()

Implementation as proposed by Joshua Block in Effective Java (Addison-Wesley 2001), which supplies an even distribution and is relatively fast. It is created from field f as follows:

• boolean -- code = (f ? 0 : 1)
• byte, char, short, int -- code = (int)f
• long -- code = (int)(f ^ (f >>>32))
• float -- code = Float.floatToIntBits(f);
• double -- long l = Double.doubleToLongBits(f); code = (int)(l ^ (l >>> 32))
• all Objects, (where equals( ) calls equals( ) for this field) -- code = f.hashCode( )
• Array -- Apply above rules to each element

Combining the hash code(s) computed above: result = 37 * result + code;

Overrides:

hashCode in class TextureTileRequest

Returns:

(int) ( result >>> 32 ) ^ (int) result;
