Constructor Detail

StructureDefHelper

public StructureDefHelper()

Method Detail

getName

public java.lang.String getName()

Description copied from interface: StructureDef

Returns the structure's name (short form).

Specified by:

getName in interface StructureDef

Returns:

name of the structure.

getFullName

public java.lang.String getFullName()

Description copied from interface: StructureDef

Returns the structure's fully qualified name.

Specified by:

getFullName in interface StructureDef

Returns:

fully qualified name of the structure.

getDefName

public java.lang.String getDefName()

Description copied from interface: StructureDef

Returns the structure's base definition name (short form). Note that, in some cases, a StructureDef may have an instance name and definition name. For example, for a View Object, getName() returns the VO's instance name and getDefName() returns the View definition's name.

Specified by:

getDefName in interface StructureDef

Returns:

name of the structure's base definition.

getDefFullName

public java.lang.String getDefFullName()

Description copied from interface: StructureDef

Returns the fully qualified name of the structure's base definition. Note that, in some cases, a StructureDef may have an instance name and definition name. For example, for a View Object, getFullName() returns the VO's full instance name and getDefFullName() returns the View definition's full name.

Specified by:

getDefFullName in interface StructureDef

Returns:

fully qualified name of the structure's base definition.

setName

public void setName(java.lang.String name)

getAttributeDefs

public AttributeDef[] getAttributeDefs()

Description copied from interface: StructureDef

Gets the defined attributes.

Specified by:

getAttributeDefs in interface StructureDef

Returns:

an array of attribute definitions.

getAttributeCount

public int getAttributeCount()

Description copied from interface: StructureDef

Returns the number of defined attributes.

Specified by:

getAttributeCount in interface StructureDef

Returns:

the number of attributes.

findAttributeDef

public AttributeDef findAttributeDef(java.lang.String attrName)

Description copied from interface: StructureDef

Gets an attribute definition, given its name.

Specified by:

findAttributeDef in interface StructureDef

Parameters:

attrName - the name of an AttributeDef.

Returns:

an attribute definition

lookupAttributeDef

public AttributeDef lookupAttributeDef(java.lang.String name)

Description copied from interface: StructureDef

Gets an attribute definition, given its name.

Specified by:

lookupAttributeDef in interface StructureDef

Parameters:

name - the name of an AttributeDef.

Returns:

an attribute definition if found, null otherwise

getAttributeDef

public AttributeDef getAttributeDef(int index)

Description copied from interface: StructureDef

Gets an attribute definition, given its index.

Specified by:

getAttributeDef in interface StructureDef

Parameters:

index - the index of an AttributeDef, where the leftmost attribute has index zero.

Returns:

an attribute definition.

getAttributeIndexOf

public int getAttributeIndexOf(java.lang.String name)

Description copied from interface: StructureDef

Finds the index (0-based) of the named attribute.

Specified by:

getAttributeIndexOf in interface StructureDef

Parameters:

name - the attribute's name.

Returns:

an integer in the range 0 to getAttributeCount() - 1. If the named attribute is not found, it returns -1.

getNewAttributeDefHelper

protected AttributeDefHelper getNewAttributeDefHelper()

addDynamicAttribute

public AttributeDef addDynamicAttribute(java.lang.String name,
                                        int index)

addViewLinkAccessor
