Method Detail

setMessageSource

public void setMessageSource(org.springframework.context.MessageSource source)

Description copied from interface: Constraint

The message source to evaluate the default messages from

Specified by:

setMessageSource in interface Constraint

Specified by:

setMessageSource in interface org.springframework.context.MessageSourceAware

getPropertyName

public java.lang.String getPropertyName()

Specified by:

getPropertyName in interface Constraint

Returns:

The property name of the constraint

setOwningClass

public void setOwningClass(java.lang.Class constraintOwningClass)

The class the constraint applies to

Specified by:

setOwningClass in interface Constraint

See Also:

Constraint.setOwningClass(java.lang.Class)

setPropertyName

public void setPropertyName(java.lang.String constraintPropertyName)

Description copied from interface: Constraint

The name of the property the constraint applies to

Specified by:

setPropertyName in interface Constraint

Parameters:

constraintPropertyName - The constraintPropertyName to set.

setParameter

public void setParameter(java.lang.Object constraintParameter)

Description copied from interface: Constraint

The parameter which the constraint is validated against.

Specified by:

setParameter in interface Constraint

Parameters:

constraintParameter - The constraintParameter to set.

getParameter

public java.lang.Object getParameter()

Specified by:

getParameter in interface Constraint

checkState

protected void checkState()

validate
