Constructor Detail

AbstractArgumentOption

protected AbstractArgumentOption(OptionManager owner,
                                 String commandline,
                                 String property,
                                 Object defValue)

Initializes the option.

Parameters:

owner - the owner of this option

commandline - the commandline string to identify the option (no leading dash)

property - the name of bean property

defValue - the default value, if null then the owner's current state is used

Method Detail

isMultiple

public boolean isMultiple()

Returns true if the option can appear multiple times (for array properties).

Returns:

true if the option can appear multiple times.

hasBaseClass

public boolean hasBaseClass()

Returns whether a base class could be determined.

Returns:

true if a base class is available

getBaseClass

public Class getBaseClass()

Returns the base class of this option. In case of arrays the class of the elements.

Returns:

the class

isVariableAttached

public boolean isVariableAttached()

Whether a variable has been attached to the option.

Returns:

true if a variable placeholder has been set

setVariable

public String setVariable(String value)

Sets the variable placeholder to use, or null to disable.

Parameters:

value - the variable placeholder

Returns:

null if successfully set/unset, otherwise error message

getVariable

public String getVariable()

Returns the variable placeholder, if any.

Returns:

the variable placeholder, or null if none set

getVariableName

public String getVariableName()

Returns the variable name (without the surrounding "@{" and "}"), if any.

Returns:

the variable placeholder, or null if none set

isVariableModified

public boolean isVariableModified()

Returns whether the variable got updated in the meantime and needs propagating.

Returns:

true if the variable got updated

isVariableReferencingObject

public boolean isVariableReferencingObject()

Returns whether the variable points to a global actor or storage.

Gets triggered when a variable changed (added, modified, removed).

Specified by:

variableChanged in interface VariableChangeListener

Parameters:

e - the event

updateVariable

public String updateVariable()

Updates the variable, i.e., retrieves the value for the variable and calls the read-method of this option to set it.

Returns:

null if successfully updated, otherwise error message

updateVariable

public String updateVariable(boolean silent)

Updates the variable, i.e., retrieves the value for the variable and calls the read-method of this option to set it.

Parameters:

silent - whether to suppress error messages in the console

updateVariable

public String updateVariable(boolean silent,
                             Logger log)

Updates the variable, i.e., retrieves the value for the variable and calls the read-method of this option to set it.

Parameters:
