Class ParameterSet

public class ParameterSet extends Object

A ParameterSet is a set of parameters supplied when calling a template. It is a collection of id-value pairs, the ids being numeric aliases for the parameter name, unique within a stylesheet

Field Summary
static ParameterSet	EMPTY_PARAMETER_SET
static int	NOT_SUPPLIED
static int	SUPPLIED
static int	SUPPLIED_AND_CHECKED

Constructor Summary
	ParameterSet() Create an empty parameter set
	ParameterSet(int capacity) Create a parameter set specifying the initial capacity
	ParameterSet(ParameterSet existing, int extra) Create a parameter set as a copy of an existing parameter set

Method Summary
void	clear() Clear all values
int	getIndex(int id) Get the inedx position of a parameter
ValueRepresentation	getValue(int index) Get the value of the parameter at a given index
boolean	isTypeChecked(int index) Determine whether the parameter at a given index has been type-checked
void	materializeValues() If any values are non-memo closures, expand them
void	put(int id, ValueRepresentation value, boolean checked) Add a parameter to the ParameterSet

Constructor Detail

ParameterSet

public ParameterSet()

Create an empty parameter set

ParameterSet

public ParameterSet(int capacity)

Create a parameter set specifying the initial capacity

ParameterSet

public ParameterSet(ParameterSet existing, int extra)

Create a parameter set as a copy of an existing parameter set

Method Detail

clear

public void clear()

Clear all values

getIndex

public int getIndex(int id)

Get the inedx position of a parameter

Parameters: id The numeric parameter id, representing its name.

Returns: The index position of the parameter, or -1 if not defined

getValue

public ValueRepresentation getValue(int index)

Get the value of the parameter at a given index

isTypeChecked

public boolean isTypeChecked(int index)

Determine whether the parameter at a given index has been type-checked

materializeValues

public void materializeValues()

If any values are non-memo closures, expand them

put

public void put(int id, ValueRepresentation value, boolean checked)

Add a parameter to the ParameterSet

Parameters: id The parameter id, representing its name. value The value of the parameter checked True if the caller has done static type checking against the required type
