Obtains an instance of the meta-bean for mutable beans.

The properties will be determined using reflection to find the PropertyDefinition annotation. The field names must be specified as reflection does not return fields in source code order.

Type Parameters:

B - the type of the bean

Parameters:

beanType - the bean type, not null

fieldNames - the field names, not null

builderSupplier - the supplier of bean builders, not null

getters - the getter functions, not null

setters - the setter functions, not null

Returns:

the meta-bean, not null

withAlias

public MinimalMetaBean<T> withAlias(java.lang.String alias,
                                    java.lang.String realName)

Adds an alias to the meta-bean.

When using metaProperty(String), the alias will return the meta-property of the real name.

Parameters:

alias - the alias

realName - the real name

Returns:

the new meta-bean instance

Throws:

java.lang.IllegalArgumentException - if the realName is invalid

isBuildable

public boolean isBuildable()

Description copied from interface: MetaBean

Checks whether this bean is buildable or not.

A buildable bean can be constructed using MetaBean.builder(). If this method returns true then builder() must return a valid builder. If this method returns false then builder() must throw UnsupportedOperationException.

Specified by:

isBuildable in interface MetaBean

Returns:

true if this bean is buildable

builder

public BeanBuilder<T> builder()

Description copied from interface: MetaBean

Creates a bean builder that can be used to create an instance of this bean.

The builder is used in two main ways. The first is to allow immutable beans to be constructed. The second is to enable automated tools like serialization/deserialization.

The builder can be thought of as a Map of MetaProperty to value. Note that the implementation is not necessarily an actual map.

Specified by:

builder in interface MetaBean

Specified by:

builder in interface TypedMetaBean<T extends Bean>

Returns:

the bean builder, not null

beanType

public java.lang.Class<T> beanType()

Description copied from interface: MetaBean

Get the type of the bean, represented as a Class.

A MetaBean can be thought of as the equivalent of Class but for beans. This method allows the actual Class instance of the bean to be obtained.

Specified by:

beanType in interface MetaBean

Specified by:

beanType in interface TypedMetaBean<T extends Bean>

Returns:

the type of the bean, not null

metaProperty

public <R> MetaProperty<R> metaProperty(java.lang.String propertyName)

Description copied from interface: MetaBean

Gets a meta-property by name.

Each meta-bean manages a single bean with a known set of properties. This method returns the property with the specified name.

The base interface throws an exception if the name is not recognised. By contrast, the DynamicMetaBean subinterface creates the property on demand.

Specified by:

metaProperty in interface MetaBean

Type Parameters:

R - the property type, optional, enabling auto-casting

Parameters:

propertyName - the property name to retrieve, not null

Returns:

the meta property, not null

metaPropertyMap

public java.util.Map<java.lang.String,MetaProperty<?>> metaPropertyMap()

Description copied from interface: MetaBean

Gets the map of meta-properties, keyed by property name.

Where possible, use MetaBean.metaPropertyIterable() instead as it typically has better performance.

Specified by:

metaPropertyMap in interface MetaBean

Returns:

the unmodifiable map of meta property objects, not null

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Returns a string that summarises the meta-bean.

Overrides:

toString in class java.lang.Object

Returns:

a summary string, not null
