Method Detail

getSourceRole

public java.lang.String getSourceRole(IntegrationObjectItemAttributeModel attributeDefinitionModel)

Description copied from interface: AssociationGenerator

Derives the source role from the given attribute definition model

Specified by:

getSourceRole in interface AssociationGenerator

Parameters:

attributeDefinitionModel - the integration object attribute definition model

Returns:

the source role

getTargetRole

public java.lang.String getTargetRole(IntegrationObjectItemAttributeModel attributeDefinitionModel)

Description copied from interface: AssociationGenerator

Derives the target role from the given attribute definition model

Specified by:

getTargetRole in interface AssociationGenerator

Parameters:

attributeDefinitionModel - the integration object attribute definition model

Returns:

the target role

getAssociationName

public java.lang.String getAssociationName(IntegrationObjectItemAttributeModel attributeDefinitionModel)

Description copied from interface: AssociationGenerator

Derives the association name from the given attribute definition model

Specified by:

getAssociationName in interface AssociationGenerator

Parameters:

attributeDefinitionModel - the integration object attribute definition model

Returns:

the association name

checkIsApplicablePrecondition

protected void checkIsApplicablePrecondition(IntegrationObjectItemAttributeModel attributeDefinitionModel)

Runs safety checks on the specified attribute definition model, to make sure it can be analyzed by the AssociationGenerator.isApplicable(IntegrationObjectItemAttributeModel) method. Specifically it checks the the model is not null and contains an AttributeDescriptorModel.

Parameters:

attributeDefinitionModel - a model to analyze

getAssociationName

protected java.lang.String getAssociationName(TypeAttributeDescriptor descriptor)

Generates association name based on the the provided attribute descriptor.

Parameters:

descriptor - a descriptor to generate the association name for.

Returns:

name of the descriptor in "FK_<item_type>_<attribute_type>" format, where item_type is the type containing the attribute descriptor and attribute_type is the type of the attribute values or, in other words, type referenced by the attribute.

asDescriptor

protected TypeAttributeDescriptor asDescriptor(IntegrationObjectItemAttributeModel attributeDefinitionModel)

Converts attribute model to an attribute descriptor.

Parameters:

attributeDefinitionModel - a model to convert.

Returns:

attribute descriptor for the specified attribute model.

getSourceRole

protected java.lang.String getSourceRole(TypeAttributeDescriptor descriptor)

Generates an association source role.

Parameters:

descriptor - an attribute descriptor to generate the source role for.

Returns:

type code of the TypeDescriptor containing the attribute descriptor.

See Also:

TypeAttributeDescriptor.getTypeDescriptor(), TypeDescriptor.getItemCode()

getTargetRole

protected java.lang.String getTargetRole(TypeAttributeDescriptor descriptor)

Generates an association target role.

Parameters:

descriptor - an attribute descriptor to generate the target role from.

Returns:

type code of the TypeDescriptor referenced by the attribute descriptor (type of the attribute values) or the attribute name if the source type is the same as the target type in the association.

See Also:

TypeAttributeDescriptor.getAttributeType(), TypeDescriptor.getItemCode(), TypeAttributeDescriptor.getAttributeName()

getTargetType

protected java.lang.String getTargetType(TypeAttributeDescriptor descriptor)

Generates an association target type.

Parameters:

descriptor - an attribute descriptor to generate the target type from.

Returns:

type code of the TypeDescriptor referenced by the attribute descriptor (type of the attribute values).

See Also:

TypeAttributeDescriptor.getAttributeType(), TypeDescriptor.getItemCode()

getTargetType

protected java.lang.String getTargetType(IntegrationObjectItemAttributeModel attributeModel)

Generates an association target type.

Parameters:

attributeModel - an attribute descriptor to generate the target type from.

Returns:

type code of the TypeDescriptor referenced by the attribute descriptor (type of the attribute values).

See Also:

TypeAttributeDescriptor.getAttributeType(), TypeDescriptor.getItemCode()

getSourceCardinality

protected org.apache.olingo.odata2.api.edm.EdmMultiplicity getSourceCardinality(TypeAttributeDescriptor descriptor)

Determines cardinality of the source type presented in the specified attribute descriptor. Normally the source type is the item type containing the attribute.

Parameters:

descriptor - descriptor to derive the cardinality from

Returns:

multiplicity

getTargetCardinality

protected org.apache.olingo.odata2.api.edm.EdmMultiplicity getTargetCardinality(TypeAttributeDescriptor descriptor)

Determines cardinality of the target type presented in the specified attribute descriptor. Normally the target type is the item type returned by the attribute.

Parameters:

descriptor - descriptor to derive the cardinality from

Returns:

multiplicity
