  • Method Details

    • parseLayoutConstraint

      public static LC parseLayoutConstraint(String s)
      Parses the layout constraints and stores the parsed values in the transient (cache) member varables.
      Parameters:
      s - The String to parse. Should not be null and must be lower case and trimmed.
      Returns:
      The parsed constraint. Never null.
      Throws:
      RuntimeException - if the constaint was not valid.

    • parseRowConstraints

      public static AC parseRowConstraints(String s)
      Parses the column or rows constraints. They normally looks something like "[min:pref]rel[10px][]".
      Parameters:
      s - The string to parse. Not null.
      Returns:
      An array of DimConstraints that is as manu are there exist "[...]" sections in the string that is parsed.
      Throws:
      RuntimeException - if the constaint was not valid.

    • parseColumnConstraints

      public static AC parseColumnConstraints(String s)
      Parses the column or rows constraints. They normally looks something like "[min:pref]rel[10px][]".
      Parameters:
      s - The string to parse. Not null.
      Returns:
      An array of DimConstraints that is as manu are there exist "[...]" sections in the string that is parsed.
      Throws:
      RuntimeException - if the constaint was not valid.

    • parseComponentConstraints

      public static Map<ComponentWrapper,CC> parseComponentConstraints(Map<ComponentWrapper,String> constrMap)
      Parses all component constraints and stores the parsed values in the transient (cache) member varables.
      Parameters:
      constrMap - The constraints as Strings. Strings must be lower case and trimmed
      Returns:
      The parsed constraints. Never null.

    • parseComponentConstraint

      public static CC parseComponentConstraint(String s)
      Parses one component constraint and returns the parsed value.
      Parameters:
      s - The string to parse. Should not be null and must be lower case and trimmed.
      Returns:
      The parsed constraint. Never null.
      Throws:
      RuntimeException - if the constaint was not valid.

    • parseInsets

      public static UnitValue[] parseInsets(String s, boolean acceptPanel)
      Parses insets which consists of 1-4 UnitValues.
      Parameters:
      s - The string to parse. E.g. "10 10 10 10" or "20". If less than 4 groups the last will be used for the missing.
      acceptPanel - If "panel" and "dialog" should be accepted. They are used to access platform defaults.
      Returns:
      An array of length 4 with the parsed insets.
      Throws:
      IllegalArgumentException - if the parsing could not be done.

    • parseBoundSize

      public static BoundSize parseBoundSize(String s, boolean isGap, boolean isHor)
      Parses a single "min:pref:max" value. May look something like "10px:20lp:30%" or "pref!".
      Parameters:
      s - The string to parse. Not null.
      isGap - If this bound size is a gap (different empty string handling).
      isHor - If the size is for the horizontal dimension.
      Returns:
      A bound size that may be null if the string was "null", "n" or null.

    • parseUnitValueOrAlign

      public static UnitValue parseUnitValueOrAlign(String s, boolean isHor, UnitValue emptyReplacement)
      Parses a single unit value that may also be an alignment as parsed by parseAlignKeywords(String, boolean).
      Parameters:
      s - The string to parse. Not null. May look something like "10px" or "5dlu".
      isHor - If the value is for the horizontal dimension.
      emptyReplacement - A replacement if s is empty. May be null.
      Returns:
      The parsed unit value. May be null.

    • parseUnitValue

      public static UnitValue parseUnitValue(String s, boolean isHor)
      Parses a single unit value. E.g. "10px" or "5in"
      Parameters:
      s - The string to parse. Not null. May look something like "10px" or "5dlu".
      isHor - If the value is for the horizontal dimension.
      Returns:
      The parsed unit value. null is empty string,

    • prepare

      public static final String prepare(String s)
      Makes null "", trimms and converts to lower case.
      Parameters:
      s - The string
