Class FontValue

java.lang.Object
generic.theme.ThemeValue<Font>
generic.theme.FontValue
All Implemented Interfaces:
Comparable<ThemeValue<Font>>
public class FontValue extends ThemeValue<Font>
A class for storing Font values that have a String id (e.g. font.foo.bar) and either a concrete font or a reference id which is the String id of another FontValue that it will inherit its font from. So if this class's font value is non-null, the refId will be null and if the class's refId is non-null, then the font value will be null.

      value - the Font to associate with the given id

    • FontValue

      public FontValue(String id, String refId)
      Constructor used when the FontValue will inherit its Font from another FontValue. The font value field will be null.
      Parameters:

    • getSerializationString

      public String getSerializationString()
      Description copied from class: ThemeValue
      Returns the "key = value" String for writing this ThemeValue to a file
      Specified by:
      getSerializationString in class ThemeValue<Font>
      Returns:
      the "key = value" String for writing this ThemeValue to a file

    • isExternal

      public boolean isExternal()
      Description copied from class: ThemeValue
      True if this value is one that is one that is defined outside of the application, such as a Java Look and Feel key.
      Specified by:
      isExternal in class ThemeValue<Font>
      Returns:
      true if external

    • get

      public Font get(GThemeValueMap values)
      Description copied from class: ThemeValue
      Returns the T value for this instance, following references as needed. Uses the given preferredValues map to resolve references. If the value can't be resolved by following reference chains, an error stack trace will be generated and the default T value will be returned. In rare situations where it is acceptable for the value to not be resolvable, use the ThemeValue.hasResolvableValue(GThemeValueMap) method first.
      Overrides:
      get in class ThemeValue<Font>
      Parameters:
      values - the GThemeValueMap used to resolve references if this instance doesn't have an actual value.
      Returns:
      the T value for this instance, following references as needed.

    • fontToString

      public static String fontToString(Font font)
      Converts a file to a string.
      Parameters:
      font - the font to convert to a String
      Returns:
      a String that represents the font

    • isFontKey

      public static boolean isFontKey(String key)
      Returns true if the given key string is a valid external key for a font value
      Parameters:
      key - the key string to test
      Returns:
      true if the given key string is a valid external key for a font value

    • parse

      public static FontValue parse(String key, String value) throws ParseException
      Parses the value string into a font or reference and creates a new FontValue using the given key and the parse results.
      Parameters:
      key - the key to associate the parsed value with
      value - the font value to parse
      Returns:
      a FontValue with the given key and the parsed value
      Throws:
      ParseException - if there is an exception parsing

    • getStyle

      public static int getStyle(String styleString)
      Returns the Font style int for the given style string
      Parameters:
      styleString - the string to convert to a Font style int
      Returns:
      the Font style int for the given style string

    • getReferredValue

      protected FontValue getReferredValue(GThemeValueMap values, String refId)
      Description copied from class: ThemeValue
      Returns the ThemeValue referred to by this ThemeValue. Needs to be overridden by concrete classes as they know the correct method to call on the preferredValues map.
      Specified by:
      getReferredValue in class ThemeValue<Font>
      Parameters:
      values - the GThemeValueMap to be used to resolve the reference id
      refId - the id of the reference ThemeValue
      Returns:
      the ThemeValue referred to by this ThemeValue.

    • getUnresolvedReferenceValue

      protected Font getUnresolvedReferenceValue(String primaryId, String unresolvedId)
      Description copied from class: ThemeValue
      Returns the T to be used if the indirect reference couldn't be resolved.
      Specified by:
      getUnresolvedReferenceValue in class ThemeValue<Font>
      Parameters:
      primaryId - the id we are trying to get a value for
      unresolvedId - the reference id that couldn't be resolved
      Returns:
