Detailed Description

Base abstract class for all attributes. Use azrtti to get the appropriate version. Of course if NULL there is a data mismatch of attributes.

Member Function Documentation

◆ CanDomInvoke()

virtual bool AZ::Attribute::CanDomInvoke ( const AZ::Dom::Value arguments) const
inlinevirtual

Returns true if this attribute is invokable, given a set of arguments.

Parameters
argumentsA Dom::Value that must contain an Array of arguments for this invokable attribute.

Reimplemented in AZ::AttributeFunction< R(Args...)>, AZ::AttributeInvocable< Invocable >, and AZ::AttributeMemberFunction< R(C::*)(Args...)>.

◆ DomInvoke()

virtual AZ::Dom::Value AZ::Attribute::DomInvoke ( void *  instance,
const AZ::Dom::Value arguments 
)
inlinevirtual

Attempts to execute this attribute given an array of Dom::Values as parameters.

Parameters
argumentsA Dom::Value that must contain an Array of arguments for this invokable attribute.
Returns
A Dom::Value containing the marshalled result of the function call (null if the call returned void)

Reimplemented in AZ::AttributeInvocable< Invocable >, AZ::AttributeFunction< R(Args...)>, and AZ::AttributeMemberFunction< R(C::*)(Args...)>.

◆ GetAsDomValue()

virtual AZ::Dom::Value AZ::Attribute::GetAsDomValue ( void *  instance)
inlinevirtual

Gets a marshalled Dom::Value representation of this attribute bound to a given instance. By default this is just abbreviated to a marshalled version of the data stored in the attribute, but for invokable attributes, override this method to serializes a pointer to the instance and this attribute

Reimplemented in AZ::AttributeData< T >, AZ::AttributeMemberData< T C::* >, AZ::AttributeMemberFunction< R(C::*)(Args...)>, and AZ::AttributeMemberFunction< R(C::*)(Args...) const >.

◆ IsInvokable()

virtual bool AZ::Attribute::IsInvokable ( ) const
inlinevirtual

Returns true if this attribute is an invokable function or method.

Reimplemented in AZ::AttributeFunction< R(Args...)>, AZ::AttributeInvocable< Invocable >, and AZ::AttributeMemberFunction< R(C::*)(Args...)>.
