Constructor Detail

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   java.lang.String type)

Creates a new accessor definition as a java type collection.

Parameters:

id - unique id for the definition.

parent - parent structure definition that this accessor is a part of.

type - the data type defined as a java type available for the system.

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   java.lang.String type,
                   java.lang.String elementType)

Creates a new accessor definition as a collection of a scalar type.

Parameters:

id - unique id for the definition

parent - parent structure definition that this accessor is a part of.

type - the data type defined as a java type available for the system.

elementType - the java type of each element in the collection.

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   java.lang.String type,
                   java.lang.String elementName,
                   java.lang.String elementType)

Creates a new accessor definition as a collection of a scalar type.

Parameters:

id - unique id for the definition

parent - parent structure definition that this accessor is a part of.

type - the data type defined as a java type available for the system.

elementName - the name of element in the collection.

elementType - the java type of each element in the collection.

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   StructureDefinition struct,
                   boolean isCollection)

Creates a new accessor definition as a complex type.

Accessors can be used to define the complex structure for which a java type may not be defined. For accessors that are collection of scalar types, use the constructor with the additional isScalarCollection parameter.

Parameters:

id - unique id for the definition.

parent - parent structure definition that this accessor is a part of.

struct - the complex structer that describes this accessor.

isCollection - indicates if the accessor is a collection.

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   StructureDefinition struct,
                   boolean isCollection,
                   boolean isScalarCollection)

Creates a new accessor definition as a complex type.

Accessors can be used to define the complex structure for which a java type may not be defined.

Parameters:

id - unique id for the definition.

parent - parent structure definition that this accessor is a part of.

struct - the complex structer that describes this accessor.

isCollection - indicates if the accessor is a collection.

isScalarCollection - indicates if the accessor is a collection of scalars.

AccessorDef

public AccessorDef(java.lang.String id,
                   StructureDefinition parent,
                   boolean isCollection)

Creates a new accessor definition as a complex type.

Accessors can be used to define the complex structure for which a java type may not be defined.

Parameters:

id - unique id for the definition.

parent - parent structure definition that this accessor is a part of.

isCollection - indicates if the accessor is a collection.

Method Detail

getFullName

public java.lang.String getFullName()

Returns the bind path for this accessor. Runtime fetches data depending on the bind path defined.

Specified by:

getFullName in interface NamedDefinition

Overrides:

getFullName in class AttributeDef

Returns:

a dot (.) separated String value. If the bind path is set, it returns <bind_path>.<this_name>. Otherwise it returns <parent_path>.<this_name>.

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.

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

Returns:

The definition of the parent accessor.

getDefinitionType

public int getDefinitionType()

Description copied from class: BaseValueObjectDefinition

Retrieves the type of the variable. It can be one of the TYPE_* contants definied in VariableDefinition.

Specified by:

getDefinitionType in interface Definition

Overrides:

getDefinitionType in class AttributeDef

Returns:

Always return TYPE_PRIMITIVE.

setAsCollection

public void setAsCollection()

Sets this accessor as a collection type.

setCollectionStructure

public void setCollectionStructure(StructureDefinition def)

Set the structure definition for the collection if the return is a collection. Collection structures usually contain methods applicable for the collection.

setStructure

public void setStructure(StructureDefinition struct)

setParentAccessor

public void setParentAccessor(AccessorDefinition parentAccessor)

clone

public AccessorDef clone(StructureDef parentStruct,
                         java.lang.String id)

Clones the accessor with a new id and a new parent.

Parameters:

parentStruct - the parent structure definition of the cloned accessor.

id - id of the new accessor.

Returns:

a cloned AccessorDef value.
