Container class for all geometry.
All Houdini geometry is stored in a GA_Detail class. The detail stores lists of attributes (GA_Attribute) which are maintained in GA_AttributeSet collections. The attribute set contains 4 separate classes of attribute based on the GA_AttributeOwner enum.
Definition at line 96 of file GA_Detail.h.
Definition at line 2226 of file GA_Detail.h.
When destroying points, there are three different modes when dealing with primitives that reference the points. These modes cause different behaviours when notifying primitives about point deletion. The behaviour is determined by the result of primitive->dereferencePoint() or primitive->dereferencePoints().

| bool | isprimary = true, |

| Pstorage | determines the precision of the P attribute. |
| isprimary | determines the default value of the P attribute. true yields (0,0,0) as the default, and false yields (0,0,1), for use by GD_Detail, where the z component is actually the point weight for NURBS/Bezier trim/profile curves. P will have typeinfo "hpoint" if secondary, and "point" if primary. |

Destructor.
| void GA_Detail::addTailInitializer | ( | GA_Attribute * | attrib | ) |
Add/Remove an attribute to the tail-initialization list.
When attributes grow in size, they usually initialize their values to the default value. However, some attributes may not adhere to this rule, or due to space optimizations, may have the values set to non-default values. In this case, they should be added to the tail-initialization list. When new elements are appended to the detail, they will be told to re-initialize the new element. Otherwise, the detail will assume that the element values are at their default value.
When removing, the method will return true if the attribute was a tail initializer.

Append a contiguous block of primitives and a contiguous block of vertices, with each primitive having nvertices_each vertices, though the vertices will be unwired, so the caller is responsible for wiring the vertices to points. Make absolutely sure you know what you're doing if you call this! It's used by GEO_PrimPoly::buildBlock() and GEO_PrimTetrahedron:: buildBlock().

Reimplemented in GU_Detail.
| void GA_Detail::bumpAllDataIds | ( | ) |
This bumps all data IDs in this detail, including point, vertex, primitive, and detail attribute data IDs, the primitive list data ID, and edge group data IDs.
| void GA_Detail::bumpDataIdsForAddOrRemove | ( | bool | added_or_removed_points, |
| bool | added_or_removed_vertices, | ||
| bool | added_or_removed_primitives | ||
| ) |
Call this to bump the appropriate data IDs when points, vertices, or primitives have been added or removed. If you're not 100% sure whether an element type has been added or removed, it's better to err on the side of safety and pass true for it.
| void GA_Detail::bumpDataIdsForRewire | ( | ) |
Call this to bump the appropriate topology data IDs when vertices have been rewired to different points.
If vertices have been added or removed, or if they've been "stolen" by a different primitive, just call bumpDataIdsForAddOrRemove(____,true,____) instead. If points have been added or removed, but vertices have only been rewired, call bumpDataIdsForAddOrRemove(true,false,false) in addition to this.

Copy all attribute values from srcoff to destoff for attributes accepted by filter. If no filter is specified, all public attributes and non-internal groups are copied.
NOTE: If you're copying multiple offsets, it's much faster to do: For each attribute, copy data for all offsets; rather than: For each offset, copy data in all attributes. These functions are only for if the former is too awkward to do in some case.

Count memory usage using a UT_MemoryCounter in order to count shared memory correctly. If inclusive is true, the size of this object is counted, else only memory owned by this object is counted.

Utility casting functions used by GA_GBMacros.h to maintain (source code) type compatibility with the old implementations that used the derived GD/GEO_PrimList objects.
The first argument is used solely to infer the templatized type. Derived classes (GD_Detail/GEO_Detail) should contain embedded GB_MACRO_PRIM_TYPE typedef to specify the proper derived type to use for the cast.

Given a point, returns a vertex that it references. More than one vertex may refer to a single point, and it is quite possible that no vertices refer to the point. GA_INVALID_OFFSET is returned if no vertices match. See getVerticesReferencingPoint() for methods to get all the points.

| bool GA_Detail::removeTailInitializer | ( | GA_Attribute * | attrib | ) |
Add/Remove an attribute to the tail-initialization list.
When attributes grow in size, they usually initialize their values to the default value. However, some attributes may not adhere to this rule, or due to space optimizations, may have the values set to non-default values. In this case, they should be added to the tail-initialization list. When new elements are appended to the detail, they will be told to re-initialize the new element. Otherwise, the detail will assume that the element values are at their default value.
When removing, the method will return true if the attribute was a tail initializer.

| void GA_Detail::replaceWith | ( | const GA_Detail & | src, |

| bool | full_copy = false |
||
| ) |
Fast version of merge for the common case of completely replacing all of this detail with the source detail, using data IDs to avoid copying things that are the same. This does not copy private scope attributes (except topology) or internal groups. When skip is given, all processing of attributes matching the filter will be skipped. The result is that skipped attributes may or may not exist afterwards, and they also won't be initialized in any expected way. The assumption is that the caller will fully handle creation, initialization, or deletion of skipped attributes. If 'full_copy is true, internal groups and private attribute are also considered.'

Fast version of merge for the case of completely replacing all of this detail with the points from the source detail, using data IDs to avoid copying things that are the same. This does not copy private scope attributes (except topology) or internal groups. It will act as if replaceWith was called and then all primitives were deleted, so vertex/primitive attributes will be transferred, but there will be no vertices or primitives. When skip is given, all processing of attributes matching the filter will be skipped. The result is that skipped attributes may or may not exist afterwards, and they also won't be initialized in any expected way. The assumption is that the caller will fully handle creation, initialization, or deletion of skipped attributes.

| IOStatus GA_Detail::stat | ( | UT_JSONParser & | p, |

Stat a disk file rather than loading the entire geometry. (see GA_STAT_LEVEL) The method cannot be static since the primitive factory is required. The primitive factory stores the IO table for the geometry.
When performing a stat on a disk file, if the format supports it, only the header of the file is loaded. This means that the full information for the geometry isn't available. Thus, this will give you different information than if you run stat() on geometry that's fully loaded into memory.
If you inspect a .geo file, you can see the information that's available. For example, you can get the "primcount_summary" using the GA_Stat::getInfoOptions() method.
