Constructor Detail

PatternSequence

public PatternSequence(PatternElement[] elems)

creates a PatternSequence from an array of PatternElements

PatternSequence

public PatternSequence(Vector elems)

creates a PatternSequence from a Vector of PatternElements

Method Detail

toString

public String toString()

returns a printable representation of the PatternSequence, consisting of the constituent PatternElements, separated by spaces.

Specified by:

toString in class PatternElement

toGraph

public PatternGraph toGraph(Id id)

converts the PatternSequence to a graph representation. A PatternSequence with n elements is converted into a PatternGraph with n-1 InternalPatternNodes:
a b c d
becomes
--a--> O --b--> O --c--> O --d-->
where 'O' is an internal pattern node.
