Constructor Detail

XmlFeatureTypeMapping

public XmlFeatureTypeMapping()

No parameters constructor for use by the digester configuration engine as a JavaBean

XmlFeatureTypeMapping

public XmlFeatureTypeMapping(FeatureSource<? extends FeatureType,? extends Feature> source,
                             AttributeDescriptor target,
                             List<AttributeMapping> mappings,
                             NamespaceSupport namespaces,
                             String itemXpath)

Method Detail

getExpressionsIgnoreIndex

public List<Expression> getExpressionsIgnoreIndex(XPathUtil.StepList targetPath)

getAttributeMappingsByExpression

public List<AttributeMapping> getAttributeMappingsByExpression(Expression sourceExpression)

Finds the attribute mappings for the given source expression.

Overrides:

getAttributeMappingsByExpression in class FeatureTypeMapping

Returns:

list of matching attribute mappings

getAttributeMappingByLabel

public AttributeMapping getAttributeMappingByLabel(String label)

Finds an attribute mapping by label.

Parameters:

label - The attribute mapping label.

Returns:

Attribute mapping that matches the label, or null.

getStringMapping

public AttributeMapping getStringMapping(XPathUtil.StepList exactPath)

Finds the attribute mapping for the target expression exactPath

Parameters:

exactPath - the xpath expression on the target schema to find the mapping for

Returns:

the attribute mapping that match 1:1 with exactPath or null if

populateFeatureData

public void populateFeatureData()
                         throws IOException

Throws:

IOException

getValue

protected Expression getValue(String xpathPrefix,
                              Expression node,
                              AttributeMapping mapping)

findMappingsFor

public List<Expression> findMappingsFor(XPathUtil.StepList propertyName,
                                        boolean includeNestedMappings)

Looks up for attribute mappings matching the xpath expression propertyName.

If any step in propertyName has index greater than 1, any mapping for the same property applies, regardless of the mapping. For example, if there are mappings for gml:name[1], gml:name[2] and gml:name[3], but propertyName is just gml:name, all three mappings apply.

Overrides:

findMappingsFor in class FeatureTypeMapping
