Method Detail

setLimits

public void setLimits(int minOccurs,
             int maxOccurs)

Description copied from interface: ListType

Sets list limits.

Specified by:

setLimits in interface ListType

Description copied from interface: ListType

Sets the default value encoded as a string.

Specified by:

setDefaultValue in interface ListType

getFieldName

public String getFieldName()

Description copied from interface: ListType

The field name if any was specified.

This is used to more for outputting the list as XML and for compatibility with XSD.

Specified by:

getFieldName in interface ListType

Returns:

the field name

getFieldType

public Type getFieldType()

Description copied from interface: ListType

Get the field describing the element type the list accept.

Specified by:

getFieldType in interface ListType

Returns:

the field describing the list element types

getField

public Field getField()

Description copied from interface: ListType

Get the field defining the elements stored by this list.

Specified by:

getField in interface ListType

Returns:

the field

getDefaultValue

public Object getDefaultValue()

Description copied from interface: ListType

Gets the default value of the list elements, if any.

Specified by:

getDefaultValue in interface ListType

Returns:

the default value or null if none

getType

public Type getType()

getMinCount

public int getMinCount()

Description copied from interface: ListType

Gets the required minimum count of elements in this list.

Specified by:

getMinCount in interface ListType

Returns:

the minimum count of required elements

getMaxCount

public int getMaxCount()

Description copied from interface: ListType

Gets the required maximum count of allowed elements in this list.

Specified by:

getMaxCount in interface ListType

Returns:

the maximum count of allowed elements

isListType

public boolean isListType()

Description copied from interface: Type

Tests whether this type is a list type.

Specified by:

isListType in interface Type

Overrides:

isListType in class AbstractType

Returns:

true if is a list type, false otherwise

decode

public Object decode(String string)

Description copied from interface: Type

Decodes the string representation into an object of this type.

Returns null if the string can not be decoded.

Specified by:

decode in interface Type

Overrides:

decode in class AbstractType

Parameters:

string - the string to decode

Returns:

the converted object that can be use as a value for an object of this type or null if the given object cannot be converted

validate

public boolean validate(Object object)
                 throws TypeException

Description copied from interface: Type

Tests whether the given object is of this type.

Specified by:

validate in interface Type

Overrides:

validate in class AbstractType

Parameters:

object - the object to test

Returns:

true if the given object if of this type, false otherwise

Throws:

TypeException - if an error occurs trying to retrieve the supertypes

newInstance

public Object newInstance()

Description copied from interface: Type

Creates a new instance according to this type and filled with default values.

Specified by:

newInstance in interface Type

Overrides:

newInstance in class AbstractType

Returns:

convert

public Object convert(Object object)
               throws TypeException

Description copied from interface: Type

Converts the given value to an object compatible with the associated type.

Specified by:

convert in interface Type

Parameters:

object - the value to convert

Returns:

the converted value

Throws:

TypeException - if the value to convert is not compatible with the associated type

isArray

public boolean isArray()

Description copied from interface: ListType

Whether the instances of this list are arrays.

Specified by:

isArray in interface ListType

isScalarList

public boolean isScalarList()

Description copied from interface: ListType

This method is provided for compatibility. Existing code is mapping scalar lists to arrays but this should be changed in order to map only explicit scalar list (those declared using xs:list) to arrays and not all list that have scalar items.

Specified by:

isScalarList in interface ListType

Returns:

true if the list items are of a scalar type TODO FIXME XXX remove the method and use instead isArray
