Method Summary | |
---|---|
static BoundSize | parseBoundSize(String s, boolean isGap, boolean isHor) Parses a singele "min:pref:max" value. |
static AC | parseColumnConstraints(String s) Parses the column or rows constraints. |
static CC | parseComponentConstraint(String s) Parses one component constraint and returns the parsed value. |
static Map<ComponentWrapper,CC> | parseComponentConstraints(Map<ComponentWrapper,String> constrMap) Parses all component constraints and stores the parsed values in the transient (cache) member varables. |
static UnitValue[] | parseInsets(String s, boolean acceptPanel) Parses insets which consists of 1-4 UnitValue s. |
static LC | parseLayoutConstraint(String s) Parses the layout constraints and stores the parsed values in the transient (cache) member varables. |
static AC | parseRowConstraints(String s) Parses the column or rows constraints. |
static UnitValue | parseUnitValue(String s, boolean isHor) Parses a single unit value. |
static UnitValue | parseUnitValueOrAlign(String s, boolean isHor, UnitValue emptyReplacement) Parses a single unit value that may also be an alignment as parsed by ConstraintParser. |
static String | prepare(String s) Makes null "", trimms and converts to lower case. |
"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
.
"[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.
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.
Parameters: constrMap The constraints as String
s. Strings must be lower case and trimmed
Returns: The parsed constraints. Never null
.
UnitValue
s.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.
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.
"[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.
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,
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
.
