Constructor Detail

MultiAttributeType

public MultiAttributeType(AttributeType validator)

Constructor with validator.

Parameters:

validator - Name of this attribute.

MultiAttributeType

public MultiAttributeType(AttributeType validator,
                          int maxOccur)

Constructor with validator and maxOccurs

Parameters:

validator - Name of this attribute.

maxOccur - Number of instances of this attribute in the schema.

MultiAttributeType

public MultiAttributeType(AttributeType validator,
                          int maxOccur,
                          int minOccur)

Constructor with validator, minOccurs and maxOccurs

Parameters:

validator - Name of this attribute.

maxOccur - Number of instances of this attribute in the schema.

minOccur - Class type of this attribute.

Method Detail

getMaxOccurs

public int getMaxOccurs()

Gets the maxOccur of this attribute.

Specified by:

getMaxOccurs in interface AttributeType

Overrides:

getMaxOccurs in class DefaultAttributeType

Returns:

MaxOccur.

getMinOccurs

public int getMinOccurs()

Gets the minimum number of elements that pass the validator that must be in the list to validate.

Specified by:

getMinOccurs in interface AttributeType

Overrides:

getMinOccurs in class DefaultAttributeType

Returns:

MaxOccur.

isGeometry

public boolean isGeometry()

Returns whether the attribute is a geometry. Should this be false? Even if the attributes are geometries? Because this itself isn't actually a geometry, so it can't be used as a geometry.

Overrides:

isGeometry in class DefaultAttributeType

Returns:

true if the attribute's type is a geometry.

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Returns a clone of this object.

Returns:

a copy of this attribute type.

Throws:

java.lang.CloneNotSupportedException - if clone is not supported.

validate

public void validate(java.lang.Object attribute)
              throws java.lang.IllegalArgumentException

Whether the tested object is a Feature and its attributes validate against the featureType. An IllegalArgumentException reporting the error in validation is thrown if validation fails..

Specified by:

validate in interface AttributeType

Overrides:

validate in class DefaultAttributeType

Parameters:

attribute - The object to be tested for validity.

Throws:

java.lang.IllegalArgumentException - if the object does not validate.

parse

public java.lang.Object parse(java.lang.Object value)
                       throws java.lang.IllegalArgumentException

If a single object is passed in then it is parsed into a list with just it as the element. If an array is passed in then it is turned into a list.

Specified by:

parse in interface AttributeType

Overrides:

parse in class DefaultAttributeType

Parameters:

value - the object to attempt parsing of.

Returns:

value converted to the preferred storage of this AttributeType. If no parsing was possible then the same object is returned.

Throws:

java.lang.IllegalArgumentException - if parsing is attempted and is unsuccessful.

Task:

REVISIT: implement this method as described in this comment.

toString

public java.lang.String toString()

Gets a representation of this object as a string.

Overrides:

toString in class DefaultAttributeType

Returns:

A representation of this object as a string
