IBeanTypeMetaInfo

public IBeanTypeMetaInfo(Class<T> beanType,
                         BeanStyle beanStyle,
                         List<IBeanFieldMetaInfo> fieldMetaInfos,
                         Method customEqualsMethod,
                         Method customHashCodeMethod)

Creates a new IBeanTypeMetaInfo with all contained information.

Parameters:

beanType - the IBean type the meta information is related to

beanStyle - the bean style that was used for parsing the bean type

fieldMetaInfos - meta information about all fields contained in the bean type; may not be null but may be an empty list

customEqualsMethod - a Method that contains a bean type individual implementation of Object.equals(); may be null

customHashCodeMethod - a Method that contains a bean type individual implementation of Object.hashCode(); may be null

Method Detail

beanType

public Class<T> beanType()

Gives the related bean type.

Returns:

the bean class this meta information is related to

beanStyle

public BeanStyle beanStyle()

Gives the bean style the bean type complies to.

Returns:

the BeanStyle that was used for parsing the bean type

fieldMetaInfos

public List<IBeanFieldMetaInfo> fieldMetaInfos()

Provides IBeanFieldMetaInfo for all fields of the bean type.

Returns:

the meta information about all contained fields of the bean type

customEqualsMethod

public Optional<Method> customEqualsMethod()

Provides a method containing custom implementation of Object.equals(). The method is named _equals by convention.

Returns:

the optional method

customHashCodeMethod

public Optional<Method> customHashCodeMethod()

Provides a method containing custom implementation of Object.hashCode(). The method is named _hashCode by convention.

Returns:

the optional method

noOfFields

public int noOfFields()

Convenience method returning the number of fields contained in the bean type.

Returns:

same as this.fieldMetaInfos.size()

findFieldMetaWithMethod

public Optional<IBeanFieldMetaInfo> findFieldMetaWithMethod(Method method)

Iterates over all contained IBeanFieldMetaInfo and returns the field meta info that contains the given method either as setter or as getter.

Parameters:

method - the getter or setter to search for

Returns:

the field meta info or an empty Optional if no field info matches

findFieldMetaWithFieldName

public Optional<IBeanFieldMetaInfo> findFieldMetaWithFieldName(String fieldName)

Iterates over all contained IBeanFieldMetaInfo and returns the field meta info that belongs to a field with a given name.

Parameters:

fieldName - the name of a field to search for

Returns:

the field meta info or an empty Optional if no field name matches

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Compares this instance with any other object preferably with another IBeanTypeMetaInfo. Two IBeanTypeMetaInfo are equal if they have the same bean type and the same bean style.

Overrides:

equals in class Object
