Constructor Detail

AbstractBasisMapping

public AbstractBasisMapping()

Creates a new AbstractBasisMapping.

Method Detail

getDimensionDescription

public K getDimensionDescription(int dimension)

Specified by:

getDimensionDescription in interface edu.ucla.sspace.basis.BasisMapping<T,K>

keySet

public Set<K> keySet()

Specified by:

keySet in interface edu.ucla.sspace.basis.BasisMapping<T,K>

getDimensionInternal

protected int getDimensionInternal(K key)

Returns an integer corresponding to key. If in read only mode, -1 is returned for unseen keys. Otherwise, unseen keys are assigned a new dimension.

getMapping

protected Map<K,Integer> getMapping()

Returns the internal mapping from keys to indices.

numDimensions

public int numDimensions()

Specified by:

numDimensions in interface edu.ucla.sspace.basis.BasisMapping<T,K>

setReadOnly

public void setReadOnly(boolean readOnly)

Specified by:

setReadOnly in interface edu.ucla.sspace.basis.BasisMapping<T,K>

isReadOnly

public boolean isReadOnly()

Specified by:

isReadOnly in interface edu.ucla.sspace.basis.BasisMapping<T,K>
