compile

public final boolean compile(ITypeConverter converter,
                             ICompilationContext ctx,
                             ICompilationResultWriter messages)

Description copied from interface: IExprNode

Allow to compile the given expression with the associated and . All messages will be stored into the at the end of the performed compilation.

Parameters:

converter - Interface for conversion types

ctx - Interface for compilation context

messages - Represent where the messages compilation will be stored

Returns:

isStaticValue

public final boolean isStaticValue()

Description copied from interface: IExpression

Returns true if the expression has a static value (i.e. that does not depend on any evaluation context). In such a case, the invoke(...) method may be called with a null evaluation context.

Returns:

boolean
