Constructor Detail

StandardVariableTable

public StandardVariableTable()

Constructor with delayed initialisation of constants. The constants will be added once the init method is called

Since:

Jep 3.5

StandardVariableTable

public StandardVariableTable(VariableFactory varFac)

Constructor when the VariableFactory is known beforehand. Initialises the constants.

Parameters:

varFac - must not be null

Method Detail

addConstants

protected void addConstants(VariableFactory varFac)

Adds the constants and sets the variable factory

Parameters:

varFac - must not be null

Since:

Jep 3.5

init

public void init(Jep j)

Will add constants if we now have a variable factory.

Specified by:

init in interface JepComponent

Overrides:

init in class VariableTable

Parameters:

j - the current Jep instance
