## Detailed Description

The BasePropertyWriter is the base class for all properties, from Simple (which encompasses Scalar and Array properties) to Compound. The functions here establish the things which all properties have in common - name, metaData, propertyType, as well as upcasting capabilities. We don't want to rely on dynamic_cast - it's slow and potentially has problems across DSO interfaces.

## Member Function Documentation

## asArrayPtr()

virtual ArrayPropertyWriterPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::asArrayPtr | ( |  | ) |

virtual

Up-cast this base property to an ArrayProperty, if such an upcast is valid. This can be checked with the isArray() function. If the upcast is not valid, an empty pointer will be returned. This default implementation returns an empty pointer.

## asCompoundPtr()

virtual CompoundPropertyWriterPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::asCompoundPtr | ( |  | ) |

virtual

Up-cast this base property to a CompoundProperty, if such an upcast is valid. This can be checked with the isCompound() function. If the upcast is not valid, an empty pointer will be returned. This default implementation returns an empty pointer.

## asScalarPtr()

virtual ScalarPropertyWriterPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::asScalarPtr | ( |  | ) |

virtual

Up-cast this base property to a ScalarProperty, if such an upcast is valid. This can be checked with the isScalar() function. If the upcast is not valid, an empty pointer will be returned. This default implementation returns an empty pointer.

## getDataType()

const DataType & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getDataType | ( |  | ) | const

inline

Non-compound properties have a DataType. It is an error to call this function for CompoundProperties, and an exception will be thrown. This is a convenience function which just returns the DataType from the header that was used in creation.

Here is the call graph for this function:

## getHeader()

virtual const PropertyHeader & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getHeader | ( |  | ) | const

pure virtual

Properties are created with a collection of metadata that is stored in a lightweight structure called PropertyHeader. This returns a constant reference to the PropertyHeader which was given upon creation.

Here is the caller graph for this function:

## getMetaData()

const MetaData & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getMetaData | ( |  | ) | const

inline

All properties have MetaData. This just returns the MetaData portion of the header that was used in creation.

Definition at line 107 of file BasePropertyWriter.h.

References getHeader().

Here is the call graph for this function:

## getName()

const std::string & Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getName | ( |  | ) | const

inline

All properties have a name, which is unique amongst its siblings in the compund property they all live in. This is the name that was given when the property was created, and is part of the property header.

Definition at line 78 of file BasePropertyWriter.h.

References getHeader().

Here is the call graph for this function:

## getObject()

virtual ObjectWriterPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getObject | ( |  | ) |

pure virtual

All properties have an object that owns them, and in order to ensure the object stays alive as long as the properties do, they retain a shared pointer to their object.

## getParent()

virtual CompoundPropertyWriterPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getParent | ( |  | ) |

pure virtual

Most properties live in a compound property. (Except for the top-compound property in any object) This returns a pointer to the parent compound property.

## getPropertyType()

PropertyType Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getPropertyType | ( |  | ) | const

inline

There are three types of abstract properties. They are Scalar, Array, and Compound properties. This function returns an enum PropertyType which indicates which property type is returned. This is simply a convenience function which returns data from the PropertyHeader.

Here is the caller graph for this function:

## getTimeSampling()

TimeSamplingPtr Alembic::AbcCoreAbstract::ALEMBIC_VERSION_NS::BasePropertyWriter::getTimeSampling | ( |  | ) | const

inline

Non-compound properties have a TimeSampling. It is an error to call this function for CompoundProperties, and an exception will be thrown. This is a convenience function which just returns the TimeSamplingType from the header that was used in creation.
