Specified by:

setFeatureTypeMapping in interface MultipleValue

getAttributeMapping

public AttributeMapping getAttributeMapping()

setAttributeMapping

public void setAttributeMapping(AttributeMapping attributeMapping)

Description copied from interface: MultipleValue

Sets the attribute type mapping that contains this multi valued mapping.

Specified by:

setAttributeMapping in interface MultipleValue

getProperties

public String[] getProperties()

getValues

public List<Object> getValues(Feature features,
                              AttributeMapping attributeMapping)

Description copied from interface: MultipleValue

Returns the values extracted from the provided feature using this multivalued mapping.

Specified by:

getValues in interface MultipleValue

evaluate

public Object evaluate(Object object)

Description copied from class: AttributeExpressionImpl

Gets the value of this property from the passed object.

Specified by:

evaluate in interface Expression

Overrides:

evaluate in class AttributeExpressionImpl

Parameters:

object - Object from which we need to extract a property value.

Returns:

default implementation returns null

evaluate

public <T> T evaluate(Object object,
                      Class<T> context)

Description copied from class: AttributeExpressionImpl

Gets the value of this attribute from the passed object.

Specified by:

evaluate in interface Expression

Overrides:

evaluate in class AttributeExpressionImpl

Type Parameters:

T - The type of the returned object.

Parameters:

object - Object from which to extract attribute value.

context - Target Class

Returns:

Evaluates the given expression based on the content of the given object an an instance of context.

accept

public Object accept(ExpressionVisitor visitor,
                     Object extraData)

Description copied from class: AttributeExpressionImpl

Used by FilterVisitors to perform some action on this filter instance. Typicaly used by Filter decoders, but may also be used by any thing which needs infomration from filter structure. Implementations should always call: visitor.visit(this); It is importatant that this is not left to a parent class unless the parents API is identical.

Specified by:

accept in interface Expression

Overrides:

accept in class AttributeExpressionImpl

Parameters:

visitor - The visitor which requires access to this filter, the method must call visitor.visit(this);

getId

public String getId()

Description copied from interface: MultipleValue

Returns the ID of the multivalued mapping.

Specified by:

getId in interface MultipleValue

equals

public boolean equals(Object o)

Description copied from class: AttributeExpressionImpl

Compares this filter to the specified object. Returns true if the passed in object is the same as this expression. Checks to make sure the expression types are the same as well as the attribute paths and schemas.

Overrides:

equals in class AttributeExpressionImpl

Parameters:

o - - the object to compare this ExpressionAttribute against.

Returns:

true if specified object is equal to this filter; else false

hashCode

public int hashCode()

Description copied from class: AttributeExpressionImpl

Override of hashCode method.

Overrides:

hashCode in class AttributeExpressionImpl

Returns:

a code to hash this object by.

toString

public String toString()

Description copied from class: AttributeExpressionImpl

Return this expression as a string.

Overrides:

toString in class AttributeExpressionImpl

Returns:

String representation of this attribute expression.
