Member Data Documentation

int HAPI_ParmInfo::childIndex

Child index within its immediate parent parameter.

Definition at line 1329 of file HAPI_Common.h.

int HAPI_ParmInfo::choiceCount

Any HAPI_ParmType can be a choice list. If the parameter is a choice list, this tells you how many choices it currently has. Note that some menu parameters can have a dynamic number of choices so it is important that this count is re-checked after every cook. See HAPI_Parameters_ChoiceLists.

Definition at line 1372 of file HAPI_Common.h.

int HAPI_ParmInfo::choiceIndex

Whether the label should be displayed.

The index to use to look into the values array in order to retrieve the actual value(s) of this parameter.

Definition at line 1441 of file HAPI_Common.h.

HAPI_ChoiceListType HAPI_ParmInfo::choiceListType

Any HAPI_ParmType can be a choice list. If this is set to HAPI_CHOICELISTTYPE_NONE, than this parameter is NOT a choice list. Otherwise, the parameter is a choice list of the indicated type. See HAPI_Parameters_ChoiceLists.

Definition at line 1365 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::disabled

Whether this parm should appear enabled or disabled.

Definition at line 1423 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::disabledConditionSH

Provides the raw condition string which is used to evalute whether a parm is enabled or disabled

Definition at line 1475 of file HAPI_Common.h.

int HAPI_ParmInfo::floatValuesIndex

Whether the label should be displayed.

The index to use to look into the values array in order to retrieve the actual value(s) of this parameter.

Definition at line 1439 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::hasMax

Whether min/max exists for the parameter values.

Definition at line 1404 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::hasMin

Whether min/max exists for the parameter values.

Definition at line 1403 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::hasUIMax

Whether min/max exists for the parameter values.

Definition at line 1406 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::helpSH

The help string for this parameter.

Definition at line 1399 of file HAPI_Common.h.

HAPI_ParmId HAPI_ParmInfo::id

The parent id points to the id of the parent parm of this parm. The parent parm is something like a folder.

Definition at line 1323 of file HAPI_Common.h.

HAPI_NodeFlags HAPI_ParmInfo::inputNodeFlag

The node input parameter could have another subtype filter specified, like "Object: Geometry Only". In this case, this value will specify that extra filter. If the filter demands a node that HAPI does not support, both this and HAPI_ParmInfo::inputNodeType will be set to NONE as such a node is not settable through HAPI.

Definition at line 1453 of file HAPI_Common.h.

HAPI_NodeType HAPI_ParmInfo::inputNodeType

If this is a HAPI_PARMTYPE_NODE, this tells you what node types this parameter accepts.

Definition at line 1446 of file HAPI_Common.h.

int HAPI_ParmInfo::instanceCount

The number of parms in a multiparm instance.

Definition at line 1461 of file HAPI_Common.h.

int HAPI_ParmInfo::instanceLength

The index of the instance in the multiparm.

Definition at line 1460 of file HAPI_Common.h.

int HAPI_ParmInfo::instanceNum

See HAPI_Parameters_MultiParms.

Definition at line 1459 of file HAPI_Common.h.

int HAPI_ParmInfo::instanceStartOffset

The number of instances in a multiparm.

First instance's HAPI_ParmInfo::instanceNum. Either 0 or 1.

Definition at line 1464 of file HAPI_Common.h.

int HAPI_ParmInfo::intValuesIndex

Whether the label should be displayed.

The index to use to look into the values array in order to retrieve the actual value(s) of this parameter.

Definition at line 1438 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::invisible

Whether this parm should be hidden from the user entirely. This is mostly used to expose parameters as asset meta-data but not allow the user to directly modify them.

Definition at line 1420 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::isChildOfMultiParm

See HAPI_Parameters_MultiParms.

Definition at line 1457 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::joinNext

Definition at line 1431 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::labelNone

the next parm.

Whether this parm should be on the same line as

Definition at line 1433 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::labelSH

The label string for the parameter.

Definition at line 1386 of file HAPI_Common.h.

float HAPI_ParmInfo::max

Parameter value range, shared between int and float parameters.

Definition at line 1412 of file HAPI_Common.h.

float HAPI_ParmInfo::min

Parameter value range, shared between int and float parameters.

Definition at line 1411 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::nameSH

Note that folders are not real parameters in Houdini so they do not have names. The folder names given here are generated from the name of the folderlist (or switcher) parameter which is a parameter. The folderlist parameter simply defines how many of the "next" parameters belong to the first folder, how many of the parameters after that belong to the next folder, and so on. This means that folder names can change just by reordering the folders around so don't rely on them too much. The only guarantee here is that the folder names will be unique among all other parameter names.

Definition at line 1383 of file HAPI_Common.h.

HAPI_ParmId HAPI_ParmInfo::parentId

Parameter id of the parent of this parameter.

Definition at line 1326 of file HAPI_Common.h.

HAPI_Permissions HAPI_ParmInfo::permissions

For the majority of parameter types permission will not be applicable. For file path parameters these permissions will indicate how the asset plans to use the file: whether it will only read it, only write to it, or both. This is set in the Operator Type Properties using the Browse Mode parameter property.

Definition at line 1350 of file HAPI_Common.h.

HAPI_RampType HAPI_ParmInfo::rampType

See HAPI_Parameters_MultiParms.

Definition at line 1466 of file HAPI_Common.h.

HAPI_PrmScriptType HAPI_ParmInfo::scriptType

The Houdini script-type of the parm.

Definition at line 1335 of file HAPI_Common.h.

int HAPI_ParmInfo::size

Tuple size. For scalar parameters this value is 1, but for vector parameters this value can be greater. For example, a 3 vector would have a size of 3. For folders and folder lists, this value is the number of children they own.

Definition at line 1359 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::spare

If true, it means this parameter doesn't actually exist on the node in Houdini but was added by Houdini Engine as a spare parameter. This is just for your information. The behaviour of this parameter is not any different than a non-spare parameter.

Definition at line 1429 of file HAPI_Common.h.

int HAPI_ParmInfo::stringValuesIndex

Whether the label should be displayed.

The index to use to look into the values array in order to retrieve the actual value(s) of this parameter.

Definition at line 1440 of file HAPI_Common.h.

int HAPI_ParmInfo::tagCount

Number of tags on this paramter.

Definition at line 1353 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::templateNameSH

If this parameter is a multiparm instance than the HAPI_ParmInfo::templateNameSH will be the hash-templated parm name, containing #'s for the parts of the name that use the instance number. Compared to the HAPI_ParmInfo::nameSH, the HAPI_ParmInfo::nameSH will be the HAPI_ParmInfo::templateNameSH but with the #'s replaced by the instance number. For regular parms, the HAPI_ParmInfo::templateNameSH is identical to the HAPI_ParmInfo::nameSH.

Definition at line 1396 of file HAPI_Common.h.

HAPI_ParmType HAPI_ParmInfo::type

The HAPI type of the parm.

Definition at line 1332 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::typeInfoSH

Some parameter types require additional type information.

  • File path parameters will indicate what file extensions they expect in a space-separated list of wild-cards. This is set in the Operator Type Properties using the File Pattern parameter property. For example, for filtering by PNG and JPG only: "*.png *.jpg"

Definition at line 1343 of file HAPI_Common.h.

float HAPI_ParmInfo::UIMax

Parameter value range, shared between int and float parameters.

Definition at line 1414 of file HAPI_Common.h.

float HAPI_ParmInfo::UIMin

Parameter value range, shared between int and float parameters.

Definition at line 1413 of file HAPI_Common.h.

HAPI_Bool HAPI_ParmInfo::useMenuItemTokenAsValue

Whether or not the "Use Menu Item Token As Value" checkbox was checked in a integer menu item.

Definition at line 1478 of file HAPI_Common.h.

HAPI_StringHandle HAPI_ParmInfo::visibilityConditionSH

Provides the raw condition string which is used to evaluate the the visibility of a parm
