Class ColorLookup.GdxColorLookup

java.lang.Object
com.github.tommyettinger.textra.ColorLookup.GdxColorLookup
All Implemented Interfaces:
ColorLookup
Enclosing interface:
ColorLookup
public static class ColorLookup.GdxColorLookup extends Object implements ColorLookup
The default ColorLookup, this simply looks up key in Colors, returning 256 (fully transparent, extremely dark blue) if no Color exists by that exact name (case-sensitive), or returning the RGBA8888 value of the color otherwise. All color names are ALL_CAPS in libGDX's Colors collection by default.

  • Field Details

    • INSTANCE

      public static final ColorLookup.GdxColorLookup INSTANCE
      The only way to access a GdxColorLookup. Since this class has no state and exists only to implement an interface, it is fine that this is static.

  • Method Details

    • getRgba

      public int getRgba(String key)
      Description copied from interface: ColorLookup
      Uses key to look up an RGBA8888 color, and returns that color as an int if one was found, or returns 256 if none was found. 256 is used because it is different from the more commonly-used 0 for fully-transparent, while still being easy to remember and very rare to ever want (it is fully transparent, very dark blue). This library will never call this method with a null key, and in most cases you can safely assume key is non-null.
      Specified by:
      getRgba in interface ColorLookup
      Parameters:
      key - the String key to use to look up or build a color; should not be null.
      Returns:
      an RGBA8888 color; if 256, this can be considered to not know how to look up the given key.
