24
Base class for all VRML/X3D fields.
26
<p>Common notes for all descendants: most of them expose field or property "Value", this is (surprise, surprise!) the value of the field. Many of them also expose DefaultValue and DefaultValueExists fields/properties, these should be the default VRML value for this field. You can even change DefaultValue after the object is created.
28
<p>Most of descendants include constructor that initializes both DefaultValue and Value to the same thing, as this is what you usually want.
30
<p>Some notes about <code>Assign</code> method (inherited from TPersistent and overridied appropriately in <code>TX3DField</code> descendants):
34
<ol class="paragraph_spacing">
35
<li value="1"><p>There are some exceptions, but usually assignment is possible only when source and destination field classes are equal.</p></li>
36
<li value="2"><p>Assignment (by <code>Assign</code>, inherited from TPersistent) tries to copy everything: name (with alternative names), default value, <a class="normal" href="X3DFields.TX3DFieldOrEvent.html#IsClauseNames">IsClauseNames</a>, <a class="normal" href="X3DFields.TX3DField.html#ValueFromIsClause">ValueFromIsClause</a>, Exposed, and of course current value.
38
<p>Exceptions are things related to hierarchy of containers: <a class="normal" href="X3DFields.TX3DFieldOrEvent.html#ParentNode">ParentNode</a>, <a class="normal" href="X3DFields.TX3DFieldOrEvent.html#ParentInterfaceDeclaration">ParentInterfaceDeclaration</a>. Also <a class="normal" href="X3DFields.TX3DField.html#ExposedEventsLinked">ExposedEventsLinked</a>.
40
<p>If you want to copy only the current value, use <a class="normal" href="X3DFields.TX3DField.html#AssignValue">AssignValue</a> (or <a class="normal" href="X3DFields.TX3DField.html#AssignLerp">AssignLerp</a>, where available).</p></li>
