Method Detail

copyMembersFromInterface

protected void copyMembersFromInterface(org.jpox.metadata.InterfaceMetaData imd)

Convenience method to copy the fields from an existing interface

Overrides:

copyMembersFromInterface in class org.jpox.metadata.AbstractClassMetaData

Parameters:

imd - The class/interface that we copy from

newDefaultedProperty

protected org.jpox.metadata.AbstractMemberMetaData newDefaultedProperty(java.lang.String name)

Utility to add a defaulted FieldMetaData to the class. Override the method in ClassMetaData because we want to add JDOConfigField type. This is called when using populate() and the class has a field that isn't in the MetaData.

Overrides:

newDefaultedProperty in class org.jpox.metadata.ClassMetaData

Parameters:

name - name of field

getClassGen

public org.apache.bcel.generic.ClassGen getClassGen()

Return ClassGen instance of bcel

Returns:

ClassGen instance of bcel

getEnhanceClass

public org.apache.bcel.classfile.JavaClass getEnhanceClass()

Return original JavaClass instance of bcel

Returns:

original JavaClass instance of bcel

findField

public org.jpox.metadata.AbstractMemberMetaData findField(org.apache.bcel.classfile.Field f)

Find the specified field. Caters for the field being in this class, or in its superclass(es).

Parameters:

f - The field

Returns:

The metadata for the field

findProperty

public org.jpox.metadata.AbstractMemberMetaData findProperty(org.apache.bcel.classfile.Field f)

Find the specified property (getter/setter) for a java field Caters for the property being in this class, or in its superclass(es).

Parameters:

f - The field

Returns:

The metadata for the property
