Method Detail

createBooleanComposition

@NotNull
public static <Context> ConstraintFunction<Context,Boolean> createBooleanComposition(Iterable<ConstraintFunction<Context,Boolean>> constraints)

Creates a composition of constraint functions which returns boolean as result. Resulting constraint function returns true at only if all supplied constraint functions returns true. If none constraint functions supplied, it always returns true.

createScopeProviderComposition

@NotNull
public static <Context> ConstraintFunction<Context,ReferenceScopeProvider> createScopeProviderComposition(Iterable<ConstraintFunction<Context,ReferenceScopeProvider>> constraints)

Creates a composition of constraint functions which returns ReferenceScopeProvider as result. TODO While a scope conjunction not implemented, it returns first not-null result of supplied constraint functions

getCanBeChildConstraintFunction

public static ConstraintFunction<ConstraintContext_CanBeChild,Boolean> getCanBeChildConstraintFunction(ConstraintsDescriptor cd)

getCanBeParentConstraintFunction

public static ConstraintFunction<ConstraintContext_CanBeParent,Boolean> getCanBeParentConstraintFunction(ConstraintsDescriptor cd)

getCanBeRootConstraintFunction

public static ConstraintFunction<ConstraintContext_CanBeRoot,Boolean> getCanBeRootConstraintFunction(ConstraintsDescriptor cd)

getCanBeAncestorConstraintFunction

public static ConstraintFunction<ConstraintContext_CanBeAncestor,Boolean> getCanBeAncestorConstraintFunction(ConstraintsDescriptor cd)

getDefaultScopeConstraintFunction

public static ConstraintFunction<ConstraintContext_DefaultScopeProvider,ReferenceScopeProvider> getDefaultScopeConstraintFunction(ConstraintsDescriptor cd)
