Constructor Detail

DefaultParameterDescriptorGroup

public DefaultParameterDescriptorGroup(ParameterDescriptorGroup group)

Constructs a group with the same values than the specified one. This copy constructor may be used in order to wraps an arbitrary implementation into a Geotools one.

Since:

2.2

DefaultParameterDescriptorGroup

public DefaultParameterDescriptorGroup(String name,
                                       GeneralParameterDescriptor... parameters)

Constructs a parameter group from a name. This parameter group will be required exactly once.

Parameters:

name - The parameter group name.

parameters - The parameter descriptors for this group.

DefaultParameterDescriptorGroup

public DefaultParameterDescriptorGroup(Citation authority,
                                       String name,
                                       GeneralParameterDescriptor... parameters)

Constructs a parameter group from a name and an authority. This parameter group will be required exactly once.

Parameters:

authority - The authority (e.g. OGC).

name - The parameter group name.

parameters - The parameter descriptors for this group.

Since:

2.2

DefaultParameterDescriptorGroup

public DefaultParameterDescriptorGroup(Map<String,?> properties,
                                       GeneralParameterDescriptor... parameters)

Constructs a parameter group from a set of properties. This parameter group will be required exactly once. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

parameters - The parameter descriptors for this group.

DefaultParameterDescriptorGroup

public DefaultParameterDescriptorGroup(Map<String,?> properties,
                                       int minimumOccurs,
                                       int maximumOccurs,
                                       GeneralParameterDescriptor... parameters)

Constructs a parameter group from a set of properties. The properties map is given unchanged to the super-class constructor.

Parameters:

properties - Set of properties. Should contains at least "name".

minimumOccurs - The minimum number of times that values for this parameter group are required.

maximumOccurs - The maximum number of times that values for this parameter group are required.

parameters - The parameter descriptors for this group.

Method Detail

getMaximumOccurs

public int getMaximumOccurs()

The maximum number of times that values for this parameter group are required.

Specified by:

getMaximumOccurs in interface GeneralParameterDescriptor

Specified by:

getMaximumOccurs in class AbstractParameterDescriptor

Returns:

The maximum occurence.

See Also:

AbstractParameterDescriptor.getMinimumOccurs()

createValue

public ParameterValueGroup createValue()

Creates a new instance of parameter value group initialized with the default values. The parameter value descriptor for the created group will be this object.

Specified by:

createValue in interface GeneralParameterDescriptor

Specified by:

createValue in interface ParameterDescriptorGroup

Specified by:

createValue in class AbstractParameterDescriptor

Returns:

A new parameter initialized to its default value.

descriptors

public List<GeneralParameterDescriptor> descriptors()

Returns the parameters in this group.

Specified by:

descriptors in interface ParameterDescriptorGroup

Returns:

The descriptor of this group.

descriptor

public GeneralParameterDescriptor descriptor(String name)
                                      throws ParameterNotFoundException

Returns the first parameter in this group for the specified identifier code.

Specified by:

descriptor in interface ParameterDescriptorGroup

Parameters:

name - The case insensitive identifier code of the parameter to search for.

Returns:

The parameter for the given identifier code.

Throws:

ParameterNotFoundException - if there is no parameter for the given identifier code.

equals

public boolean equals(AbstractIdentifiedObject object,
                      boolean compareMetadata)

Compares the specified object with this parameter group for equality.

Overrides:

equals in class AbstractParameterDescriptor

Parameters:

object - The object to compare to this.

compareMetadata - true for performing a strict comparaison, or false for comparing only properties relevant to transformations.

Returns:

true if both objects are equal.

hashCode

public int hashCode()

Returns a hash value for this parameter.

Overrides:

hashCode in class AbstractParameterDescriptor

Returns:

The hash code value. This value doesn't need to be the same in past or future versions of this class.
