                  java.util.Random random)

Method Detail

getLevel

public java.lang.String getLevel()

Representation of the CopertTree level. Correspond to the first sub-table column name.

Returns:

tree level

getCategory

public java.lang.String getCategory()

getPath

select

public CopertTree select()

If there is only one CopertTree child from there, returns this child. If multiple children are present, select a random child. Return null if there is no more available child.

Returns:

a random child available from this node.

selectAll

public java.util.Collection<CopertTree> selectAll()

Parameters:

matcher - regular expression selector

Returns:

A matching child

selectAllRegExp

public java.util.Collection<CopertTree> selectAllRegExp(java.lang.String regExp)

Returns all the children associated to a key that match the given regular expression. Can be used to aggregate parameters on sub-categories(e.g. : Articulated Heavy Trucks).

Parameters:

regExp - regular expression selector

Returns:

matching children

put

public void put(java.lang.String value,
                CopertTree childValue)

getSubTable

public SubTable getSubTable()

getChildren

public java.util.HashMap<java.lang.String,CopertTree> getChildren()

isSingleLine

public boolean isSingleLine()
