Method Detail

getInlineNodeGeneratorback to summary
public Supplier<Node> getInlineNodeGenerator()

This method must return a non-null value for a segment of INLINE_NODE type, or null in any other case.

Returns:Supplier<Node>

code that creates a Node instance, or null

getParagraphNodeGeneratorback to summary
public Supplier<Region> getParagraphNodeGenerator()

This method must return a non-null value for a segment of REGION type, or null in any other case.

Returns:Supplier<Region>

code that creates a Region instance, or null

getStyleAttributeMapback to summary
public StyleAttributeMap getStyleAttributeMap(StyleResolver resolver)

This method returns StyleAttributeMap (or null) for this segment. When the model manages style names (instead of actual attributes), an instance of StyleResolver may be used to convert the style names to individual attributes. Keep in mind that different views might have different stylesheet applied and resulting in a different set of attributes.

Parameters
resolver:StyleResolver

the style resolver to use

Returns:StyleAttributeMap

style attributes

getTextback to summary
public String getText()

Returns the text associated with this segment. Must be one character for inline nodes, must be null for node paragraphs or line breaks.

Returns:String

the segment plain text

getTextLengthback to summary
public int getTextLength()

Returns the length of text in the segment, or 0 for segments that contain no text or where getText() returns null.

Returns:int

the length in characters

getTypeback to summary
public abstract StyledSegment.Type getType()

Returns the type of this StyledSegment.

Returns:StyledSegment.Type

the type

ofback to summary
