Name is Unicode, these are characters encoded according to font that will draw them.

Constructor Detail

LeafText

public LeafText(java.lang.String name,
                java.util.Map<java.lang.String,java.lang.Object> attr,
                INode parent)

LeafText

public LeafText(java.lang.String name,
                java.lang.String estr,
                java.util.Map<java.lang.String,java.lang.Object> attr,
                INode parent)

Method Detail

getText

public java.lang.String getText()

Returns Unicode text.

size

public int size()

Description copied from class: Node

Number of addressable components in node: number of children in INode, number of letters in text leaf, zero for invisible nodes such as comments, and otherwise usually one (the default).

Overrides:

size in class Node

append

public void append(Leaf l)

Description copied from class: Leaf

Append leaf to the end of this one, adjusting content, spans, and so on. The appended leaf must either immediately follow this one in the tree, or be unattached to the tree. The appended leaf should be considered invalid and not used subsequently.

Overrides:

append in class Leaf

append

public void append(java.lang.String text)

append

public void append(java.lang.String text,
                   java.lang.String estr)

clipboardNode

public void clipboardNode(java.lang.StringBuffer sb)

Description copied from class: Node

To build up selection, pass a StringBuffer to media-specific leaves, which fill it as appropriate for that medium. Need to fix this to respect subelement addressing

Overrides:

clipboardNode in class Leaf

clipboardBeforeAfter

public void clipboardBeforeAfter(java.lang.StringBuffer sb,
                                 int start,
                                 int end)

Overrides:

clipboardBeforeAfter in class Leaf

subelementCalc

public void subelementCalc(Context cx)

Calculates an array of x-position at each letter in word.

Overrides:

subelementCalc in class Leaf

Parameters:

cx - is up-to-date for this Node

subelementHit

public int subelementHit(java.awt.Point rel)

Description copied from class: Leaf

Given a geometric point within the leaf, return index of corresponding subcomponent (e.g., letter within word). See offset2rel().

Overrides:

subelementHit in class Leaf

offset2rel

public java.awt.Point offset2rel(int offset)

Description copied from class: Leaf

Given an offset into a Leaf, return corresponding subcomponent geometric point. See offset2rel().

Overrides:

offset2rel in class Leaf
