Class FieldMeta

java.lang.Object

io.ebean.enhance.entity.FieldMeta

All Implemented Interfaces:

Opcodes, EnhanceConstants, Comparable<FieldMeta>

public final class FieldMeta
extends Object
implements Opcodes, EnhanceConstants, Comparable<FieldMeta>

Holds meta data for a field.

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

Constructor Details

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 Details

compareTo

public int compareTo(FieldMeta other)

Specified by:

compareTo in interface Comparable<FieldMeta>

setIndexPosition

public void setIndexPosition(int indexPosition)

toString

public String toString()

Overrides:

toString in class Object

name

public String name()

isPrimitiveType

public boolean isPrimitiveType()

Return true if this is a primitiveType.

setNotNull

public void setNotNull()

isNullable

public boolean isNullable()

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.

isToMany

public boolean isToMany()

Return true if this is a OneToMany or ManyToMany field.

isInitMany

public boolean isInitMany()

Control initialisation of ToMany and DbArray collection properties. This means these properties are lazy initialised on demand.

addGetSetMethods

public void addGetSetMethods(ClassVisitor cv,
 ClassMeta classMeta)

Add get and set methods for field access/interception.
