Detailed Description

SdfData provides concrete scene description data storage.

An SdfData is an implementation of SdfAbstractData that simply stores specs and fields in a map keyed by path.

Member Function Documentation

virtual SDF_API void SdfData::_VisitSpecs ( SdfAbstractDataSpecVisitor visitor) const
protectedvirtual

Visits every spec in this SdfAbstractData object with the given visitor. The order in which specs are visited is undefined. The visitor may not modify the SdfAbstractData object it is visiting. This method should not call Done() on the visitor.

SdfAbstractDataSpecVisitor

Implements SdfAbstractData.

virtual SDF_API void SdfData::CreateSpec ( const SdfPath path,
SdfSpecType  specType 
)
virtual

Create a new spec at path with the given specType. If the spec already exists the spec type will be changed.

Implements SdfAbstractData.

virtual SDF_API void SdfData::Erase ( const SdfPath path,
const TfToken fieldName 
)
virtual

Remove the field at path and fieldName, if one exists.

Implements SdfAbstractData.

virtual SDF_API void SdfData::EraseSpec ( const SdfPath path)
virtual

Erase the spec at path and any fields that are on it. Note that this does not erase child specs.

Implements SdfAbstractData.

virtual SDF_API void SdfData::EraseTimeSample ( const SdfPath path,
double  time 
)
virtual

Implements SdfAbstractData.

virtual SDF_API VtValue SdfData::Get ( const SdfPath path,
const TfToken fieldName 
) const
virtual

Return the value for the given path and fieldName. Returns an empty value if none is set.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::GetBracketingTimeSamples ( double  time,
double *  tLower,
double *  tUpper 
) const
virtual

Implements SdfAbstractData.

virtual SDF_API bool SdfData::GetBracketingTimeSamplesForPath ( const SdfPath path,
double  time,
double *  tLower,
double *  tUpper 
) const
virtual

Implements SdfAbstractData.

virtual SDF_API size_t SdfData::GetNumTimeSamplesForPath ( const SdfPath path) const
virtual

Implements SdfAbstractData.

virtual SDF_API SdfSpecType SdfData::GetSpecType ( const SdfPath path) const
virtual

Return the spec type for the spec at path. Returns SdfSpecTypeUnknown if the spec doesn't exist.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::Has ( const SdfPath path,
const TfToken fieldName,
SdfAbstractDataValue value 
) const
virtual

Returns whether a value exists for the given path and fieldName. Optionally returns the value if it exists.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::Has ( const SdfPath path,
const TfToken fieldName,
VtValue value = NULL 
) const
virtual

Return whether a value exists for the given path and fieldName. Optionally returns the value if it exists.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::HasSpec ( const SdfPath path) const
virtual

Return true if this data has a spec for path.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::HasSpecAndField ( const SdfPath path,
const TfToken fieldName,
SdfAbstractDataValue value,
SdfSpecType specType 
) const
virtual

Fill specType (which cannot be nullptr) as if by a call to GetSpecType(path). If the resulting specType is not SdfSpecTypeUnknown, then act as if Has(path, fieldName, value) was called and return its result. In other words, the semantics of this function must be identical to this sequence:

*specType = GetSpecType(path);
return *specType != SdfSpecTypeUnknown && Has(path, fieldName, value);

Reimplemented from SdfAbstractData.

virtual SDF_API bool SdfData::HasSpecAndField ( const SdfPath path,
const TfToken fieldName,
VtValue value,
SdfSpecType specType 
) const
virtual

Fill specType (which cannot be nullptr) as if by a call to GetSpecType(path). If the resulting specType is not SdfSpecTypeUnknown, then act as if Has(path, fieldName, value) was called and return its result. In other words, the semantics of this function must be identical to this sequence:

*specType = GetSpecType(path);
return *specType != SdfSpecTypeUnknown && Has(path, fieldName, value);

Reimplemented from SdfAbstractData.

virtual SDF_API std::vector<TfToken> SdfData::List ( const SdfPath path) const
virtual

Return the names of all the fields that are set at path.

Implements SdfAbstractData.

virtual SDF_API std::set<double> SdfData::ListAllTimeSamples ( ) const
virtual

Implements SdfAbstractData.

virtual SDF_API std::set<double> SdfData::ListTimeSamplesForPath ( const SdfPath path) const
virtual

Implements SdfAbstractData.

virtual SDF_API void SdfData::MoveSpec ( const SdfPath oldPath,
const SdfPath newPath 
)
virtual

Move the spec at oldPath to newPath, including all the fields that are on it. This does not move any child specs.

Implements SdfAbstractData.

virtual SDF_API bool SdfData::QueryTimeSample ( const SdfPath path,
double  time,
SdfAbstractDataValue optionalValue 
) const
virtual

Implements SdfAbstractData.

virtual SDF_API bool SdfData::QueryTimeSample ( const SdfPath path,
double  time,
VtValue value 
) const
virtual

Implements SdfAbstractData.

virtual SDF_API void SdfData::Set ( const SdfPath path,
const TfToken fieldName,
const VtValue value 
)
virtual

Set the value of the given path and fieldName.

It's an error to set a field on a spec that does not exist. Setting a field to an empty VtValue is the same as calling Erase() on it.

Implements SdfAbstractData.

virtual SDF_API void SdfData::Set ( const SdfPath path,
const TfToken fieldName,
const SdfAbstractDataConstValue value 
)
virtual

Set the value of the given path and fieldName.

It's an error to set a field on a spec that does not exist.
