Member Function Documentation

◆ container()

CacheContainer * g2o::Cache::container ( )

Definition at line 67 of file cache.cpp.

References _container, and CacheContainer.

Referenced by graph(), installDependency(), and vertex().

◆ elementType()

virtual HyperGraph::HyperGraphElementType g2o::Cache::elementType ( ) const

inlinevirtual

returns the type of the graph element, see HyperGraphElementType

Implements g2o::HyperGraph::HyperGraphElement.

Definition at line 70 of file cache.h.

◆ graph()

OptimizableGraph * g2o::Cache::graph ( )

Definition at line 62 of file cache.cpp.

References container(), and g2o::CacheContainer::graph().

◆ installDependency()

Cache * g2o::Cache::installDependency	(	const std::string &	type_,
		const std::vector< int > &	parameterIndices )

protected

this function installs and satisfies a cache

Parameters

type_ the typename of the dependency

parameterIndices a vector containing the indices if the parameters in _parameters that will be used to assemble the Key of the cache being created For example if I have a cache of type C2, having parameters "A, B, and C", and it depends on a cache of type C1 that depends on the parameters A and C, the parameterIndices should contain "0, 2", since they are the positions in the parameter vector of C2 of the parameters needed to construct C1.

Returns: the newly created cache

◆ key()

◆ parameters()

ParameterVector & g2o::Cache::parameters ( )

Definition at line 69 of file cache.cpp.

References _parameters.

◆ resolveDependencies()

bool g2o::Cache::resolveDependencies ( )

protectedvirtual

Function to be called from a cache that has dependencies. It just invokes a sequence of installDependency(). Although the caches returned are stored in the _parentCache vector, it is better that you redefine your own cache member variables, for better readability

Reimplemented in g2o::CacheCamera, g2o::CacheSE2Offset, g2o::CacheSE3Offset, and g2o::tutorial::CacheSE2Offset.
