Class FieldMeta

java.lang.Object

io.ebean.enhance.entity.FieldMeta

All Implemented Interfaces:

Opcodes, EnhanceConstants

public class FieldMeta
extends Object
implements Opcodes, EnhanceConstants

Holds meta data for a field.

This can then generate the appropriate byte code for this field.

Constructor Detail

FieldMeta

public FieldMeta(ClassMeta classMeta,
                 String name,
                 String desc,
                 String fieldClass)

Construct based on field name and desc from reading byte code.

Used for reading local fields (not inherited) via visiting the class bytes.

Method Detail

setIndexPosition

public void setIndexPosition(int indexPosition)

toString

public String toString()

Overrides:

toString in class Object

getFieldName

public String getFieldName()

Return the field name.

isPrimitiveType

public boolean isPrimitiveType()

Return true if this is a primitiveType.

getName

public String getName()

Return the field name.

isObjectArray

public boolean isObjectArray()

Return true if this field type is an Array of Objects.

We can not support Object Arrays for field types.

isPersistent

public boolean isPersistent()

Return true is this is a persistent field.

isTransient

public boolean isTransient()

Return true if this is a transient field.

isId

public boolean isId()

Return true if this is an ID field.

ID fields are used in generating equals() logic based on identity.

isMany

public boolean isMany()

Return true if this is a OneToMany or ManyToMany field.

addGetSetMethods

public void addGetSetMethods(ClassVisitor cv,
                             ClassMeta classMeta)

Add get and set methods for field access/interception.
