Constructor Detail

VariableManager

public VariableManager()

Default constructor; sets the pre-defined variables

Method Detail

isVarDefined

public boolean isVarDefined(String id)

getValue

public String getValue(String id)

addNew

public boolean addNew(Variable var)

Add new variable. If the variable is already found, then it will be overridden. This will not happen only if the existing variable has override = true, or external = true. In this case, the variable will be overridden only if itself has override = true. external = true does not have such effect, so only the first external variable will be recognized.

Parameters:

var - the variable

Returns:

returns true if the variable was added

append

public void append(String id,
                   String value)

Append value to an existing variable

keys

public Iterator<String> keys()

Get the names of all variables

nonExternalKeys

public Iterator<String> nonExternalKeys()

Get the names of all variables that are not external (= from command line)

nonNonEmptyKeys

public Iterator<String> nonNonEmptyKeys()

Get the names of all variables whose value is not empty

values

public Iterator<Variable> values()

Get the current value of the variable

expand

public void expand(String varID)

Expand a variable
