Constructor Detail

ConstrainedMethod

public ConstrainedMethod(ConfigurationSource source,
                 MethodConstraintLocation location,
                 Set<MetaConstraint<?>> returnValueConstraints,
                 boolean isCascading)

Creates a new method meta data object for a parameter-less method.

Parameters:

source - The source of meta data.

location - The location of the represented method.

returnValueConstraints - The return value constraints of the represented method, if any.

isCascading - Whether a cascaded validation of the represented method's return value shall be performed or not.

ConstrainedMethod

public ConstrainedMethod(ConfigurationSource source,
                 MethodConstraintLocation location,
                 List<ConstrainedParameter> parameterMetaData,
                 Set<MetaConstraint<?>> returnValueConstraints,
                 boolean isCascading)

Creates a new method meta data object.

Parameters:

source - The source of meta data.

location - The location of the represented method.

parameterMetaData - A list with parameter meta data. The length must correspond with the number of parameters of the represented method. So this list may be empty (in case of a parameterless method), but never null.

returnValueConstraints - The return value constraints of the represented method, if any.

isCascading - Whether a cascaded validation of the represented method's return value shall be performed or not.

Method Detail

getLocation

public MethodConstraintLocation getLocation()

Description copied from interface: ConstrainedElement

Returns the location of this constrained element.

Specified by:

getLocation in interface ConstrainedElement

Overrides:

getLocation in class AbstractConstrainedElement

Returns:

The location of this constrained element.

getAllParameterMetaData

public List<ConstrainedParameter> getAllParameterMetaData()

Returns meta data for all parameters of the represented method.

Returns:

A list with parameter meta data. The length corresponds to the number of parameters of the method represented by this meta data object, so an empty list may be returned (in case of a parameterless method), but never null.

isConstrained

public boolean isConstrained()

Whether the represented method is constrained or not. This is the case if it has at least one constrained parameter, at least one parameter marked for cascaded validation, at least one return value constraint or if the return value is marked for cascaded validation.

Specified by:

isConstrained in interface ConstrainedElement

Overrides:

isConstrained in class AbstractConstrainedElement

Returns:

True, if this method is constrained by any means, false otherwise.

hasParameterConstraints

public boolean hasParameterConstraints()

Whether this method has at least one cascaded parameter or at least one parameter with constraints.

Returns:

True, if this method has at least one cascading or constrained parameter, false otherwise.

isGetterMethod

public boolean isGetterMethod()

Whether the represented method is a JavaBeans getter method or not.

Returns:

True, if this method is a getter method, false otherwise.

toString

public String toString()

Overrides:

toString in class AbstractConstrainedElement
