Method Detail

isCollection

public boolean isCollection()

Description copied from interface: AccessorDefinition

Since an accessor can return a structured object (or a collection). This function should return true when the accessor represents a collection.

Specified by:

isCollection in interface AccessorDefinition

Returns:

true if the accessor is a collection, false if it is a simple object such as a String or an int.

isScalarCollection

public boolean isScalarCollection()

Description copied from interface: AccessorDefinition

Returns true if the accessor returns a collection of scalars. Scalars are simple types that are not structured and are not collections.

Specified by:

isScalarCollection in interface AccessorDefinition

Returns:

true if the accessor is a collection of scalars, false otherwise.

getStructure

public StructureDefinition getStructure()

Description copied from interface: AccessorDefinition

Retrieves the metadata of the elements that the accessor collection contains.

Specified by:

getStructure in interface AccessorDefinition

Returns:

The metadata describing the structure of the elements in the accessor collection.

getCollectionStructure

public StructureDefinition getCollectionStructure()

Description copied from interface: AccessorDefinition

Retrieves the metadata of the collection itself. It is possible that the collection itself has operations defined, such as if the collection is a class that implements a java.util.Collection interface and contains methods for searching through its elements. Please note that this is different from the getStructure API, which returns the metadata of the collection elements.

Specified by:

getCollectionStructure in interface AccessorDefinition

Returns:

The metadata describing the structure of the collection, or null if there is none available for the collection.

isReadOnly

public boolean isReadOnly()

Description copied from interface: AttributeDefinition

Finds out whether this attribute is read-only or is updateable.

Specified by:

isReadOnly in interface AttributeDefinition

Overrides:

isReadOnly in class AttributeDefinitionImpl

Returns:

True if this attribute is read-only, false otherwise.

isKey

public boolean isKey()

Description copied from interface: AttributeDefinition

Finds out whether this attribute is the primary key of the row.

Specified by:

isKey in interface AttributeDefinition

Overrides:

isKey in class AttributeDefinitionImpl

Returns:

True if this attribute is the primary key, false otherwise.

getDefinitionType

public int getDefinitionType()

Description copied from interface: Definition

Retrieves the type of this definition. It can be one of the TYPE_* constants defined in this class. This is useful to find out the actual type of the Definition without doing an instanceof operations.

Specified by:

getDefinitionType in interface Definition

Overrides:

getDefinitionType in class AttributeDefinitionImpl

Returns:

The type of definition that this Definition implementation class implements.

resolveFullName

protected void resolveFullName()

Overrides:

resolveFullName in class AbstractNamedDefinition

getParentAccessor

public AccessorDefinition getParentAccessor()

Description copied from interface: AccessorDefinition

Retrieves the AccessorDefinition of the parent accessor. A parent accessor is the accessor from which this accessor is obtained from. For example, we have a Dept structure, which contains an accessor called emps that returns a collection of Employee. Each Employee structure in turn contains an accessor called address that returns a structured type Address. The parent accessor of address would be the accessor emps in the Dept structure.

Specified by:

getParentAccessor in interface AccessorDefinition

Overrides:

getParentAccessor in class AbstractNamedDefinition

Returns:

The definition of the parent accessor.
