copyRelationalValues
public static void copyRelationalValues(Instance inst, Instances destDataset, AttributeLocator strAtts) Copies relational values contained in the instance copied to a new dataset. The Instance must already be assigned to a dataset. This dataset and the destination dataset must have the same structure.- 参数:
inst
- the Instance containing the relational values to copy.destDataset
- the destination set of InstancesstrAtts
- an AttributeLocator containing the indices of any relational attributes in the dataset.

copyRelationalValues
public static void copyRelationalValues(Instance instance, boolean instSrcCompat, Instances srcDataset, AttributeLocator srcLoc, Instances destDataset, AttributeLocator destLoc) Takes relational values referenced by an Instance and copies them from a source dataset to a destination dataset. The instance references are updated to be valid for the destination dataset. The instance may have the structure (i.e. number and attribute position) of either dataset (this affects where references are obtained from). Only works if the number of relational attributes is the same in both indices (implicitly these relational attributes should be semantically same but just with shifted positions).- 参数:
instance
- the instance containing references to relations in the source dataset that will have references updated to be valid for the destination dataset.instSrcCompat
- true if the instance structure is the same as the source, or false if it is the same as the destination (i.e. which of the relational attribute indices contains the correct locations for this instance).srcDataset
- the dataset for which the current instance relationvalue references are valid (after any position mapping if needed)srcLoc
- an AttributeLocator containing the indices of relational attributes in the source datset.destDataset
- the dataset for which the current instance relation references need to be inserted (after any position mapping if needed)destLoc
- an AttributeLocator containing the indices of relational attributes in the destination datset.
