This is the definition of a run-time instance of a class, which would be RedCircle here. Instances have an array of Traits of various types. RedCircle has one trait (moveit) of kind Trait_Method which means the trait has a reference to a method (2).</p> <p>So if you skip to method_body_info[1] (the constructor of RedCircle) you can see at byte 323 that getProperty is called with an index of 4.</p> <pre><code>102 0x66 (323) getproperty index: 4 (moveit) </code></pre> <p>Which is a reference to the multiname constant pool.</p> <pre><code>multiname_info[4]{ kind (225): CONSTANT_QName multiname_kind_QNAME{ ns (225): 5 name (226): 7 ("moveit") } } </code></pre> <p>When it comes to calling the method it looks up the name index in the traits for the instance.</p> <pre><code>traits_info[0]{ name (281): 4 (moveit) kind (282): Trait_Method ATTR_Final (0x1): false ATTR_Override (0x2): false ATTR_Metadata (0x4): false trait_method{ disp_id (283): 0 method (284): 2 } } </code></pre> <p>Then calls the relevant method.</p> <pre><code>method_info[2]{ param_count (263): 1 return_type (264): 0 param_type[0] (265): 1 name (266): 0 flags (267): 0 NEED_ARGUMENTS (0x01): false NEED_ACTIVATION (0x02): false NEED_REST (0x04): false HAS_OPTIONAL (0x08): false SET_DXNS (0x40): false HAS_PARAM_NAMES (0x80): false } method_body_info[2]{ method (331): 2 max_stack (332): 3 local_count (333): 2 init_scope_depth (334): 10 max_scope_depth (335): 11 code_length (336): 10 208 0xD0 (337) getlocal_0 48 0x30 (338) pushscope 208 0xD0 (339) getlocal_0 208 0xD0 (340) getlocal_0 102 0x66 (341) getproperty index: 7 (x) 147 0x93 (343) decrement 97 0x61 (344) setproperty index: 7 (x) 71 0x47 (346) returnvoid exception_count (347): 0 trait_count (348): 0 } </code></pre> <p>A somewhat simplified answer, but I hope it clears up a few issues.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.
