## Member Typedef Documentation

## operator_bool_base_type

typedef IObject Alembic::Abc::ALEMBIC_VERSION_NS::IObject::operator_bool_base_type

Definition at line 60 of file IObject.h.

## this_type

typedef IObject Alembic::Abc::ALEMBIC_VERSION_NS::IObject::this_type

By convention, we always define "this_type" in every Abc class. This convention is relied upon by the unspecified-bool-type conversion.

## Member Function Documentation

## ALEMBIC_OPERATOR_BOOL()

Alembic::Abc::ALEMBIC_VERSION_NS::IObject::ALEMBIC_OPERATOR_BOOL | ( | valid() |  | ) |

The unspecified-bool-type operator casts the object to "true" if it is valid, and "false" otherwise.

## getArchive()

IArchive Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getArchive | ( |  | ) | const

This function returns the object's archive, handily wrapped in an IArchive wrapper.

Here is the caller graph for this function:

## getChild() [1/2]

IObject Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getChild | ( | const std::string & | iChildName | ) | const

This function returns an IObject wrapped constructed from the header referenced by the name. If the child of the given name does not exist, this will fail in the same way as if the equivalent constructor was called.

References IObject().

Here is the call graph for this function:

## getChild() [2/2]

IObject Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getChild | ( | size_t | iChildIndex | ) | const

This function returns an IObject constructed from the indexed object.

References IObject().

Here is the call graph for this function:

## getChildHeader() [1/2]

const AbcA::ObjectHeader * Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getChildHeader | ( | const std::string & | iName | ) | const

Return the header of an object by name. This will return a NULL pointer if no header by that name is found.

## getChildHeader() [2/2]

const AbcA::ObjectHeader & Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getChildHeader | ( | size_t | i | ) | const

This function returns the headers of each of the child objects that were written as children of this object.

## getChildrenHash()

bool Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getChildrenHash | ( | Util::Digest & | oDigest | ) |

If an aggregated child objects hash exists fill oDigest with it and return true, if it doesn't exist return false

## getFullName()

const std::string & Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getFullName | ( |  | ) | const

The full name of an object is the complete path name all the way to the root object of the archive. It is guaranteed to be fully unique within the entire archive. This is a convenience function which returns the header's full name.

## getHeader()

const AbcA::ObjectHeader & Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getHeader | ( |  | ) | const

All objects have a header, which contains all the MetaData that was specified upon their creation. This function returns a constant reference to that Header.

Referenced by Alembic::Abc::ALEMBIC_VERSION_NS::ISchemaObject< ICollectionsSchema >::ISchemaObject(), Alembic::Abc::ALEMBIC_VERSION_NS::ISchemaObject< ICollectionsSchema >::ISchemaObject(), Alembic::Abc::ALEMBIC_VERSION_NS::ISchemaObject< ICollectionsSchema >::ISchemaObject(), and getMetaData().

Here is the caller graph for this function:

## getInstancePtr()

AbcA::ObjectReaderPtr Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getInstancePtr | ( |  | ) | const

inline

Returns the original ObjectReaderPtr, if this object is an instance.

Definition at line 232 of file IObject.h.

## getMetaData()

const AbcA::MetaData & Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getMetaData | ( |  | ) | const

inline

All objects have metadata. This metadata is identical to the Metadata of the top level compoundProperty "properties". Because the metadata must exist and be initialized in order to bootstrap the object, it is guaranteed to exist and is returned by reference. This is a convenience function which returns the header's MetaData.

Definition at line 161 of file IObject.h.

References getHeader().

Here is the call graph for this function:

## getName()

const std::string & Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getName | ( |  | ) | const

All objects have a name. This name is unique amongst their siblings Returned by reference, since it is guaranteed to exist and be unchanging. This is a convenience function which returns the header's name.

## getNumChildren()

size_t Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getNumChildren | ( |  | ) | const

This function returns the number of child objects that this object has.

## getParent()

IObject Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getParent | ( |  | ) | const

This function returns the object's parent, handily wrapped in an IObject wrapper. If the object is the top level object, the IObject returned will be NULL.

References IObject().

Here is the call graph for this function:

## getProperties()

ICompoundProperty Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getProperties | ( |  | ) | const

AbcA::ObjectReaderPtr Alembic::Abc::ALEMBIC_VERSION_NS::IObject::getPtr | ( |  | ) | const

inline

getPtr, as usual, returns a shared ptr to the underlying AbcCoreAbstract object, in this case the ObjectReaderPtr. If this object happens to be an instance, it points to the instance source ObjectReaderPtr
