public final Class RichUtils

Returns the text positions at a positive offset relative to the 'start' position.

returns true if both control and model are editable

Combines style attributes, returning combined object (or null).

Parameters

lowPri:StyleAttributeMap

the low priority attributes

hiPri:StyleAttributeMap

the high priority attributes

Returns:StyleAttributeMap

the combined attributes, or null

Utility method which combines CssMetaData items in one immutable list.

The intended usage is to combine the parent and the child CssMetaData for the purposes of getClassCssMetaData() method, see for example Node#getClassCssMetaData().

Example:

private static final List<CssMetaData<? extends Styleable, ?>> STYLEABLES = CssMetaData.combine(
     <Parent>.getClassCssMetaData(),
     STYLEABLE1,
     STYLEABLE2
 );

Parameters

inheritedFromParent:List<CssMetaData<? extends Styleable, ?>>

the CssMetaData items inherited from parent, must not be null

items:CssMetaData<? extends Styleable, ?>[]

the additional items

Returns:List<CssMetaData<? extends Styleable, ?>>

the immutable list containing all of the items

Computes y midpoint of MoveTo and LineTo path elements.

Parameters

path:PathElement[]

the PathElements

Returns:double

the midpoint

dumps the path element array to a compact human-readable string

null-tolerant equals()

Creates an instance of StyleAttributeMap which contains character attributes found in the specified Text node. The following attributes will be set:

• BOLD
• FONT_FAMILY
• FONT_SIZE
• ITALIC
• STRIKE_THROUGH
• TEXT_COLOR
• UNDERLINE

Parameters

textNode:Text

the text node

Returns:StyleAttributeMap

the StyleAttributeMap instance

Returns composed or committed text.

returns a parent of the specified type, or null. if node is an instance of the specified class, returns node

Computes text length for the TextFlow embedded into TextCell, ignoring unmanagement Nodes (highlights) and counting non-Text nodes as having length=1.

Guesses the font style from the font name, until JDK-8092191 is implemented.

Parameters

lowerCaseName:String

font name, must be lowercase'd

Returns:String

font style: [ normal | italic | oblique ]

Guesses the font weight from the font name, until JDK-8092191 is implemented.

Parameters

lowerCaseName:String

font name, must be lowercase'd

Returns:String

font weight: [ normal | bold | bolder | lighter | 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 ]

Returns true if the specified lowercased font name is determined to be bold. This method is not guaranteed to work in any circumstances, see JDK-8092191

Parameters

lowerCaseFontName:String

the font name converted to lower case

Returns:boolean

true if the font is bold

Returns true if the color scheme is DARK, checking first the node's scene, then platform preferences.

Returns true if the specified lowercased font name is determined to be italic or oblique. This method is not guaranteed to work in any circumstances, see JDK-8092191

Parameters

lowerCaseFontName:String

the font name converted to lower case

Returns:boolean

true if the font is italic

Returns true if code point at the specified offset is a letter or a digit, returns false otherwise or if the offset is outside of the valid range.

Parameters

text:String

the text

offset:int

the character offset

Returns:boolean

true if the code point at the specified offset is a letter or a digit

Returns true if the font family corresponds to a logical font as defined in OpenJFX Font Setup wiki.

Parameters

family:String

the font family

Returns:boolean

true if logical, false otherwise

Convenience method for laying out the node within its parent, filling the available area. This method is equivalent to calling Region.layoutInArea(n, x, y, w, h, 0.0, Insets.EMPTY, true, true, HPos.CENTER, VPos.CENTER, snap);

Parameters

n:Node

the node to lay out

x:double

the horizontal offset of the layout area

y:double

the vertical offset of the layout area

w:double

the width of the layout area

h:double

the height of the layout area

Returns the line end offset of the given line index.

Parameters

line:int

the line index

Returns:Integer

the line offset

Returns the line index of the given character offset.

Parameters

offset:int

the character offset

Returns:int

the line index

Returns the line start offset of the given line index.

Parameters

line:int

the line index

Returns:Integer

the line start offset

Returns the offset of the next code point, or the end of the text string.

Parameters

text:String

the text

offset:int

the offset to start from

Returns:int

the offset of the next code point, or the end of the text string

null-tolerant !equals()

Converts PathElement[] in the owner's coordinates to a Bounds[] in screen coordinates. It assumes the input array is a sequence of

MoveTo (top-left)
LineTo (to top-right)
LineTo (bottom-right)
LineTo (bottom-left)
LineTo (back to top-left)

Reads a UTF8 string from the input stream. This method does not close the input stream.

Parameters

in:InputStream

the input stream

Returns:String

the string

Exceptions

IOException:

if an I/O error occurs

A safe substring method which is tolerant to null text, and offsets being outside of the text boundaries.

Parameters

text:String

source text or null

start:int

start offset, must be >= 0

end:int

end offset

Returns:String

a non-null substring

Converts Color to "#rrggbb" or "rgba(r,g,b,a)" string

elements:PathElement[]

the path elements

Returns:PathElement[]

translated path array, or null

Exceptions

RuntimeException:

if path elements contain something other than LineTo or MoveTo

Writes an Image to a byte array in PNG format.

Parameters
